List of Samurai Sentai Shinkenger characters

Samurai Sentai Shinkenger is a Japanese tokusatsu series that serves as the 33rd installment in the Super Sentai franchise and the 21st entry in the Heisei era. The series incorporates heavy elements of Japan in terms of culture, mythology and Nihon Bukkyō.

Shinkengers

The eponymous Shinkengers existed for 18 generations to protect the world from the Gedoushu, demonic beings from the Sanzu River. Based out of the Shiba House that originated from Mount Tsunobue, the Shinkengers use a kanji-based power called Modikara, which is passed down from one generation to the next. Once becoming a Shinkenger, they must renounce their past lives in order to keep their friends and family safe in case a member of the Gedoushu targets them. The Shiba House's manor is protected by a barrier of the Modikara "protect", keeping the Shinkengers safe. They use a Gap Sensor to detect the presence of a Gedoushu and its whereabouts.
The primary Shinkengers utilize the Japanese calligraphy in Ink brush to gain access to Modikara powers, either for transformation purposes or to summon other items with the proper kanji. When not in use, it assumes Mobile phone as a basic communication tool. Their sidearm is the Shinkenmaru, a katana modeled after a praxinoscope that allows them to harness the power of Secret Disks and their personal elemental attacks. Using a personal Secret Disk allows a Shinkenger to perform a Spiral Sword attack depending on the element that the disk represents. Five Spiral Sword elemental attacks can be used in the Quintuple Sword and Five-Colored Dance attacks while four can be used in the Four Continual Slash and Quadruple Sword attacks. With Shinken Gold, they can perform the Six Continual Slash attack.
After acquiring the Inromaru from the Tengen Temple and having Genta complete the device, any one of the primary Shinkengers can utilize it to assume a white-coated Super Shinkenger form that allows them to keep up with the Gedoushu forces' increasing strength and use advanced elemental attacks. Upon transformation, the user combines the Inromaru and their Shinkenmaru to form the Super Shinkenmaru, which allows them to perform upgraded versions of their Spiral Sword techniques. They also wield the Mougyu Bazooka, which can combine with their Super Shinkenmaru to form the Super Mougyu Bazooka and perform the Heretic Ruination finisher. In other media not within the series' canon, Shinken Gold is able to become Super Shinken Gold without the Inromaru.

Takeru Shiba

Takeru Shiba is the main protagonist of the series, a young man referred by his vassals and servants as Lord. He was raised since childhood by Hikoma Kusakabe to act the role of the 18th head of the Shiba House after his father gave him the Shishi Origami. His upbringing made him create a facade to look very arrogant and proud to others, claiming none can match his strength and greatness, while keeping his cool in any situation. Though he was reluctant to have the vassals fight by his side, as he wanted no one else to bear the burden, he allowed their involvement after giving them the choice to turn back or become Shinkengers out of want rather than need, as long as they are willing to finish their mission to the last detail. By the time Genta arrives, Takeru's facade is revealed as he now questions himself of how it makes him strong along with learning he shares similar attributes with Juzo before defeating him. While at times it may not appear so, Takeru does cares greatly for his vassals and when Genta arrives, he becomes more open with them. However, in a fight against Juzo, it is revealed that Takeru started to value his life more which, in Juzo's opinion, makes him weaker and makes Takeru doubt himself. In reality, Takeru has been acting as a kagemusha for the true 18th head of the Shiba House, Kaoru, who was not yet born at the time of her father's death, having been chosen for his proficiency with Modikara and his swordsmanship. When Kaoru is injured while attempting to use the Sealing Character on Doukoku, she formally adopts Takeru, making him the 19th head of the Shiba House. After defeating Doukoku in the final battle, Takeru says goodbye to Kaoru and his vassals and stays in the Shiba House with Hikoma, resuming his days now as a true samurai.
As the "Samurai of Fire, Shinken Red, Takeru's personal weapon is the Rekka Daizantou, which allows him to perform the Many Fires Profusion attack in its zanbatō-like Daizantou Mode. By inserting an alternate Secret Disk, the Rekka Daizantou can assume its cannon-like Ōdzutsu to hold the team's personal Secret Disks and perform the The Book of Five Rings finisher as well as the Six Rings Bullet finisher by adding Shinken Gold's Ika Disk to the ammunition. Using a Secret Disk with the Modikara of "Twin" created by Tanba, it can be split into a pair of swords. During the Shinkengers' team up with List of [Kamen Rider Decade characters#Tsukasa Kadoya|Kamen Rider Decade], Shinken Red uses the Blade Blade broadsword in place of his Rekka Daizantou that he loaned to the Rider in finishing off Chinomanako Diend.
In Tensou Sentai Goseiger vs. Shinkenger: Epic on Ginmaku, Takeru transforms into the black-coated Gedou Shinken Red after being brainwashed by Brajira's Dark Gosei Power to force him into cooperating with drowning Gosei World in the Sanzu River. Despite his appearance, Shinken Red retains access to his original weapons.
Takeru is portrayed by Tori Matsuzaka. As a child, he is portrayed by Masaki Takaiwa.

Ryunosuke Ikenami

Ryunosuke Ikenami is a young man who gave up becoming a kabuki actor to answer the call of serving the Shiba House. Due to his parents' upbringing, he is extremely enthusiastic and takes his role as Takeru's vassal seriously. Ryunosuke is also the engineer behind many of the Samurai Combinations, having figured out how to combine the Origami into Tenku ShinkenOh and later into SamuraiHaOh. He is initially unreceptive towards Genta, who he once called a "wannabe" samurai. As such, Ryunosuke is typically the one to lead the other vassals in Takeru's absence. When Kaoru reveals herself, Ryunosuke becomes confused about whom to follow, because he had pledged his life to the head of the Shiba family. After he receives some advice that clears his mind, he pledges his life to Takeru Shiba. After the final battle, Ryunosuke gives Takeru a kabuki-styled farewell dance and goes back to work as a kabuki actor.
As the "Samurai of Water, Shinken Blue, Ryunosuke's personal weapon is the Water Yumi, which allows him to perform the Clear and Serene attack, as well as the Samurai Flash Wave with Shinken Pink, Green, Yellow and Gold.

Mako Shiraishi

Mako Shiraishi is a strong-willed girl who fights for her ideals. She loves children and worked at a kindergarten prior to becoming a Shinkenger. When she was a little girl, her childhood was pushed aside when her parents moved to Hawaii without a word and left her in the care of her grandmother, who schooled her in the ways of bushidō. Chiaki and Kotoha both regard her as an older sister figure; Chiaki even addresses her as such. Though she is a horrible cook, Mako tries her best in order to achieve her dream of becoming a good wife and mother. Eventually, Mako is reunited with her parents and learns that her mother had become paralyzed from the waist down as a result of her tenure as the previous Shinken Pink. After the reunion and reconciliation with her mother, Mako gains a newfound conviction to defeat the Gedoushu. Because of her gentle nature, she can read other people well, especially Takeru, and readily gives her opinion regarding the situation in question. After the final battle, Mako goes to Hawaii to live with her parents.
As the "Samurai of Air, Shinken Pink, Mako's personal weapon is the Heaven Japanese war fan, which allows her to perform the Whole Sky Impact attack. In Tensou Sentai Goseiger vs. Shinkenger: Epic on Ginmaku, she performs the Pink Double Attack with Gosei Pink.
Mako is portrayed by Rin Takanashi. As a child, she is portrayed by Marina Nakajima.

Chiaki Tani

Chiaki Tani is a lazy, irresponsible, selfish, and arrogant rebel. Initially, Chiaki had no interest in becoming Takeru's vassal and often clashed with him. The only reason he even worked with Takeru was because he thought it would be fun and he wanted to protect people. He is a great strategist despite his delinquency, and comes to respect Takeru as a rival when he realizes the limits of his own abilities, pledging to pass Takeru in skill someday. Chiaki was without his mother from an early age and was raised solely by his father, who planted in him the seed of his interest in martial arts. Despite not being formally trained, he is an excellent strategist and adept with surprise attacks, thanks to his imagination and free-spiritedness. When Genta arrives, Chiaki is the first to accept him into the team. Chiaki is very protective of Kotoha and seems to be uncomfortable when Genta's friend shows an interest in her. Even though he often butts heads with Ryunosuke, Chiaki respects him immensely for his skill; in fact, they work together so well that they become able to execute tasks in sync with one another. During time off from his duties, or when he is troubled, he often plays Tekken 6: Bloodline Rebellion. He prefers American surf wear and skate wear brands like Vans and especially Gotcha, whose vintage shirts he wears in most episodes. After the final battle, Chiaki plans to take his college entrance exams.
As the "Samurai of Wood, Shinken Green, Chiaki's personal weapon is the Wood Yari, which allows him to perform the Large Treed Late Bloomer and Foliage Concealment attacks.
Chiaki is portrayed by Shogo Suzuki.

Kotoha Hanaori

Kotoha Hanaori is a clumsy and gentle 16-year-old girl who worked in a bamboo shop and speaks with a Kyoto accent. Very much a crybaby as a child, she is close to her older sister, Mitsuba, who had been training to be Shinken Yellow. When Mitsuba became ill and unable to serve as Takeru's vassal, Kotoha stepped up to take her place. Kotoha is deeply respectful of Takeru and wants to help him in any way she can. She has rather low self-esteem; she genuinely believes that she is stupid and, despite her teammates' affection for her, often feels that she is a bother to them. She idolizes Mako and strives to become more like her. Kotoha often suggests that if Mitsuba never fell ill, the Shinkengers as a whole would probably be much stronger. However, her spirits are raised after she receives a letter from Mitsuba, in which Mitsuba says that Kotoha is the true Shinken Yellow. After the final battle, Kotoha returns home to Mitsuba.
As the "Samurai of Earth, Shinken Yellow, Kotoha's personal weapon is the Land Shuriken, which allows her to perform the All Out Earth Power attack.
Kotoha is portrayed by Suzuka Morita. As a child, she is portrayed by Ayu Matsuura.

Genta Umemori

Genta Umemori is the son of a sushi chef who mysteriously disappeared prior to the beginning of the series, and a childhood friend of Takeru's. As a child, Genta often meddled in Takeru's training, which annoyed Hikoma greatly. Genta promised to help Takeru become a samurai, and in return, Takeru entrusted him with the Ika Disk. Years later, he is shown to have inherited the Gold Zushi sushi cart and to have developed his own Electronic Modikara, using the Sushi Changer cellphone to type the kanji needed. The other Shinkengers are initially suspicious of Genta until he makes his formal introduction as Shinken Gold, after he saves his teammates from a powerful Ayakshi. Though Takeru is reluctant at first, he eventually allows Genta to fulfill his promise and join the team. Genta considers himself Takeru's best friend, despite their personalities being complete opposites; Genta is as hyperactive and expressive as much as Takeru is reserved and stoic. When Kaoru reveals herself, Genta immediately disapproves of her because of his relationship with Takeru, but later accepts her when he sees that she is very kind. After the final battle, Genta leaves to open a restaurant with DaiGoyou in Paris in hopes of fulfilling his lifelong dream of receiving a three-star rating by the Michelin Guide.
Unlike the primary Shinkengers, Genta utilizes his personal Sushi Disk in conjunction with the Sushi Changer to access the latter's nigirizushi-like Sushi Mode and transform into the "Samurai of Light", Shinken Gold. In its default Sushi#sushi rice, Genta can harness the Electronic Modikara to compensate for his lack of calligraphy training. In combat, Shinken Gold uses sushi-themed accouterments, like exploding chopsticks that he uses as a projectile weapon. His sidearm is the Sakanamaru a tantō modeled after a Sakana that allows him to take out an entire platoon of Nanashi through Iaido.
Genta is portrayed by Keisuke Sohma. As a child, he is portrayed by Ryota Koshiba.

Kaoru Shiba

Kaoru Shiba is the true 18th head of the Shiba House, a position that Takeru was holding in her place. She is referred to by her vassals and servants as Princess. As the head of the Shiba House, Kaoru is the one who possesses the knowledge of the Sealing Character also known as the Gedou Seal, a Modikara passed along the Shiba bloodline. Because of this, she stayed in hiding while Takeru acted as her kagemusha to draw the Gedoushu away from her. When she grows tired of living in hiding, she masters the Sealing Character to defeat the Gedoushu and assumes her birthright. Even though she is kind and easy to work with, she underestimates the vassals' dedication to Takeru, and when she is injured in attempting to use the Sealing Character, she adopts Takeru and gives up her birthright to allow Takeru to lead the Shinkengers in defeating Doukoku. She makes another appearance in Tensou Sentai Goseiger vs. Shinkenger: Epic on Ginmaku, combining her Modikara with Alata's Gosei Power to create the Kaentornado card, which is used to free Takeru from his Gedou Shinken Red form, and allow all the Shinkengers to utilize Super Shinkenger forms.
Like Takeru, Kaoru is the "Samurai of Fire" and has the ability to become Shinken Red, referred to as Princess Shinken Red to differentiate from Takeru's version. Her secret training allows her to easily adopt all of the weaponry the others had used before her appearance, such as utilizing the Inromaru to become Super Shinken Red.
Kaoru is portrayed by Runa Natsui.

Ushi Origami: A massive ox-themed Origami that drags a black gissha behind it.

Allies

Hikoma Kusakabe

Hikoma Kusakabe is Takeru's retainer and guardian. He also serves as the Shinkengers' mentor; it is he who gathered the four vassals when the Gedoushu revived. The Shinkengers affectionately call him "Jii". Every year, he gets one day off, which he uses to visit his wife's grave and visit his daughter and granddaughter. His relationship with Takeru and his vassals runs deep; he takes great care to ensure that they are safe and that they are ready to fight, and he supplies them with information and weaponry. Though Genta frequently annoys him, Hikoma acknowledges the younger man's skill with Modikara and eventually does accept and connect with him. Like Mako, he is adept at reading people and often helps the vassals with their personal problems. When he goes to a hospital to be treated for a hip injury, he happens upon the Hikari Studio and gives invaluable advice to Tsukasa Kadoya during the meeting of the worlds of Kamen Rider Decade and Samurai Sentai Shinkenger. While Hikoma does not typically take up arms himself, his "battle" is to ensure that Takeru and his vassals remain safe and will always have someplace to which they can return. When Kaoru makes her appearance, Hikoma remains loyal to Takeru, but bears no ill will towards Kaoru; he respects her for both her title and for the kind and diligent young woman that she is. After the final battle, he stays with Takeru even when he insists that he go visit his family and encourages Takeru to join him to experience other lifestyles other than just the samurai life.
Hikoma is portrayed by Goro Ibuki.

Kuroko

The kuroko are the Shiba House's servants who, like their namesakes, "set up" the scene during the Shinkengers' transformation. As they do not possess Modikara proficiency, they are not able to fight against the Gedoushu physically and as such, they are not directly involved in combat, although they do help evacuate civilians away from danger. They are skilled in many comparatively mundane things and are tasked with doing household chores, and help citizens in the nearby town to the best of their ability, when the Shinkengers are not in battle. Kaoru has her own group of Kuroko, who wear slightly different robes bearing the Shiba family crest.

Sakutaro Komatsu: A former kuroko who had previously served Masataka, much like Ryunosuke serves Takeru. After the previous head of the Shiba House died, Sakutaro lost his will to continue as a servant of the Shiba House and took to the life of a fisherman. However, meeting Ryunosuke opens Sakutaro's eyes to the reason why he had served the Shiba House as he helps Ryunosuke in obtaining the Kajiki Origami. He later secretly resumes his duty as a kuroko; he helps Ryunosuke through his own crisis of confidence, and gives Kaoru a larger fan with which she can put Tanba in his place. Sakutaro Komatsu is portrayed by Gotaro Tsunashima.

DaiGoyou

DaiGoyou is a support robot created by Genta during his temporary fear of sushi, infusing his Electronic Modikara with a lantern in his sushi cart to be able to fight for him when needed, referring to his creator as "Boss". He is normally in the splintered form of his Secret Disk shooting Paper lantern, which forms the majority of his robot mode, and Jitte Mode, which Shinken Gold uses as a weapon to perform the DaiGoyou Jitte Strike attack; this part forms DaiGoyou's arms. DaiGoyou also has the ability to fly in his paper lantern mode. Genta originally designed DaiGoyou after the lanterns carried by the Jitte-wielding guardsmen from old samurai films. Ryunosuke points out that these were mere guardsmen and not samurai, so the kanji for Samurai on DaiGoyou's lantern is actually a misrepresentation, much to Genta and DaiGoyou's chagrin.
Once enlarged by the "big" Modikara, Daigoyou can form into a Samurai Giant through the DaiGoyou Big Transformation by fusing its default Paper Lantern body and its Jitte forming its arms. His techniques include the DaiGoyou Big Lighting and the DaiGoyou Big Spin, and he can retract his head and compress his torso to dodge enemy attacks. His finisher is the Secret Disks Turbulence Shot, which fires disks from his body. While combined, he requires occasional Secret Disk jam-clearing, which simply requires slapping the bottom of the lantern's handle.

Shinken DaiGoyou: An alternative formation where an enlarged DaiGoyou replaced the Shishi Origami as the ShinkenOh's torso. Using the Jitte Mode parts as a weapon, Shinken DaiGoyou's finisher is the Jitte Straight.

Daigoyou is voiced by Hironori Miyata.

Credited as the Previous Head, Masataka is portrayed by Masaya Matsukaze.

Gedoushu

The Gedoushu are malevolent spirits who arise as the result of sin-tainted souls that enter into the Sanzu River within the land of the dead. The Gedoshu maintain their wretched existence with the water of the Sanzu, and in order to maintain the river's levels, they constantly enter into the human world with the intent of running amok in order to feed the river with negative emotions of humans. If a Gedoshu spends too long in the human world, it eventually dries out, and petrifies if it can not return to the Sanzu. Cursed to be in a state between life and death, a Gedoushu can only be free of its existence if it is slain upon taking its Second Life, or if it is able to let go of the upādāna that damned it in the first place. The Gedoushu under Doukoku reside on the Takarabune that sails along the Sanzu River. Others spend their time within the River itself until Doukoku or some other powerful being calls them. Using their ability to enter the living world through cracks and narrow gaps, Doukoku's minions set up a plan to terrorize humans in any way possible so that the river overflows to point of flooding into the mortal realm in order for them to invade in full fury. The Gedoushu can also become powerful during the time of Bon Festival.
In the world of Shinkenger, the Gedoushu are the inspiration of all the yōkai in Japanese mythology. The main Gedoushu characters are modeled after the Seven Lucky Gods and sea creatures.

Doukoku Chimatsuri

Doukoku Chimatsuri is the Bishamonten/spiny lobster-themed leader of the Gedoushu. He is in a constant state of rage, originally endless until he heard the sound of Usuyuki's shamisen, becoming obsessed with her as he later takes her upon her rebirth into Dayu to soothe his rage along with sake. He targeted the Shiba House's previous Shinkengers, making it his goal to eliminate the Shiba House so no one would be able to stop him. However, while fighting the 17th head of the Shiba House, he was sealed away as the previous Shinken Red died. This seal was incomplete, and Doukoku was able to revive by the time of the next generation. To reach his goal again, Doukoku sends out Ayakashi to terrorize humans so the Sanzu River can overflow its banks into the mortal realm and enable him to unleash his full fury. This method of attack was later revealed to how he loses the rejuvenating qualities of its waters much faster than any other member of the Gedoushu and takes longer to soak the river's waters back into his body.
Learning of the seal placed on him, Doukoku briefly changes his plans to target Takeru as the death of the Shiba House would ensure that he would never be sealed again. But when that plan failed, Doukoku has his force carry on the original plan without giving wind of this knowledge to any Ayakashi with his own agenda. During the summer while in a comatose state that leaves him open to his enemies, Doukoku manages to suppress his magnified power. Later, after learning of Akamaro's true colors, Doukoku risks his life to enter the mortal realm to repair Dayu's shamisen after driving off Akumaro and defeating Shinken Red. As a result, he has to be submerged in the Sanzu River to rehydrate. But after the Shiba House's true 18th head is revealed, Doukoku's followers attempt to speed up his awakening by increasing the amount of suffering until Dayu uses Shinza's anguish to bring Doukoku back to the mortal realm. After absorbing Dayu's energy to heal his body, Doukoku gains immunity to the Sealing Character and can now endure being in the mortal realm without drying up. As a result, Doukoku overpowers the Shinkengers before bringing the Rokumon Junk into the mortal realm when the Sanzu River floods the city. Thinking he had broken the Shinkengers' spirits when they attempt to defeat him, Doukoku is immobilized before Shinken Blue delivers the final blow. Assuming his second life, Doukoku overpowers SamuraiHaOh, blasting it and throwing off its components until only ShinkenOh remains, then impales it on his sword. However, the Shinkengers take advantage of the events and mortally wound him before he explodes. He attempts to take the Shinkengers down with him, but this fails as they survive the explosion.
Doukoku's personal weapons are the Shōryū Bakuzantō and the Kōryū Gaiseitō. He also possessed the power to seal his fellow Gedoushu.
Doukoku is voiced by Rintarō Nishi.

Tayu

Tayu Usukawa is Doukoku's Benzaiten/sea slug/Futakuchi-onna-themed right hand and the only one he is kind to, provided she knows her place as his obedient, unquestioning servant. Doukoku takes her in after her rebirth as a Gedoushu, giving her the name she now goes by and telling her that she has nowhere else to go but to him. But her unique origins set her apart from normal Gedoshu as she can move freely in the mortal realm. In life, she was Usuyuki a shamisen player who obsessed over a man named Shinza. Scorned that he loved another woman instead of her, Usuyuki set fire to the building holding his wedding ceremony, killing him, his bride, and the entirety of their wedding party, in a suicidal crime of passion. Seeing that her love would remain unrequited to the bitter end, Usuyuki's emotions corrupt her soul and caused her rebirth into Tayu.
Of all the Gedoushu, Tayu has the most trouble getting along with the Ayakashi because of her previous life as a human, which she makes attempts to reclaim. One failed attempt results with her being saved by Juzo, developing feelings for the Gedounin as she begins to defy Doukoku's orders with her shamisen damaged as a result. Though her feelings for Shinza had long died, Tayu refuses to give him up as it would end her existence and desires to know the purpose behind it. Leaving Doukoku, Tayu wanders aimlessly until she is found by Akumaro who recruits her to his group in return for her instrument's restoration. Upon learning that Akamaro never intended to repair her instrument, she attempts to reclaim her shamisen until Dokouku comes to her aid, using a piece of his body to restore the shamisen and reminding her of her place by his side. Soon after Akumaro's demise, Tayu returns to the Rokumon Junk to assist in Doukoku's reawakening. To that end, after finally having the answers to her questions, Tayu deliberately has Shinken Pink destroy her shamisen to not only discard her past life, but to also use Shinza's anguished soul to revive Doukoku. She later uses the last of her powers to restore Doukoku's body, giving him immunity to the Sealing Character and independence from the Sanzu River. With only her kimono remaining, Doukoku later throws it into the Sanzu River as a final respect to her.
Tayu's shamisen is forcefully bounded to Shinza's soul, creating the eerie and unsettling songs that serve to soothe Doukoku's rage. The shamisen's headstock also doubles as the hilt of a shortsword Tayu uses in battle. While her shamisen is under "repair" by Akumaro, Tayu uses the Sange Hankontō dagger as her alternative weapon.
Tayu is voiced by Romi Park, who also portrayed Usuyuki in her lone appearance on-screen.

Shitari

Shitari of the Bones is the Fukurokuju/squid-themed Gedoushu's strategist, a squid-headed demon with a shakujō who awaited for Doukoku's revival. Shitari sees humans as mere specimens for his research, uncovering means to overflow the Sanzu River. He also possessed texts from the Shiba House which he used to learn about the seal placed on Doukoku. Though he warns Doukoku not to trouble himself with the Shiba House's sealing character so not to attract attention from certain Ayakashi, Shitari recruits Isagitsune in an attempt to slake his curiosity on what the sealing character is. He later recruits Oinogare in an attempt to re-open a well the Gedoushu used in the past as their base of operations by sacrificing nine maidens, formally introducing himself to the Shinkengers as a result.
While Doukoku is in a vulnerable state struggling with his surging power, the rogue Ayakashi Gozunagumo bullies Shitari into extorting the sealing character from Shinken Red. Despite poisoning Takeru, Shitari fails to get him to reveal the sealing character due to the combined interference of Shinken Gold and Juzo. When Doukoku revives and punishes Gozunagumo, Shitari freely confesses that the one thing he values above Doukoku is his own life and gains forgiveness from his leader out of amusement with his honesty. When Akumaro arrives, Shitari expresses a great deal of distrust over the mysterious Gedoushu and not as much shocked when his impression of him was accurate yet was powerless to do anything against him as he realized Akumaro's intentions. After Dayu returns, Shitari decides to kill off Takeru, only to learn the truth behind him and the Shiba House's true leader and giving up one half of his life, in an attempt to speed up Doukoku's reawakening at the cost of having no second life should he be killed. He remains on the Rokumon Junk during Doukoku's final battle with the Shinkengers, going down with the ship as it sinks in response to its master's death while proclaiming that he will survive regardless of what happens.
Shitari later returns in Tensou Sentai Goseiger vs. Shinkenger: Epic on Ginmaku, becoming Brajira's right hand servant until learning his plan to drain the Sanzu River and refusing to go along with it. But during the climactic battle, gathering an army of followers to kill Buredoran and reclaim the Sanzu River, Shitari ends up facing the Gokaigers when they traveled from the near future and they mistakenly believe him to be a hindrance in their own affairs. With his army ultimately devastated, Shitari is destroyed by Gokai Red using the Go-On Red Ranger Key.
Shitari is voiced by Chō.

Juzo

Juzo Fuwa is a mysterious Shōjō/Jurōjin/skeleton-themed Gedoushu, regarded by the others as a lone wolf, yet he seems to know more than Doukoku about the Sanzu River's true potential. 200 years ago, Fuwa was a samurai in life who made a living as an assassin, disenchanted with the ways of bushidō and thriving more on the pleasure of killing his opponents in battle until he can no longer be physically able to wield a sword. He meets Akumaro who provides him with the Uramasa katana, seemingly unaware that the blade was forged from the souls of his family who tried to free him from his blood lust. When he contracts a fatal illness, Fuwa enters the Sanzu River to cheat death, completely discarding the goodness in his heart to become a Gedounin, a half-Gedoushu that can freely exist in both realms and assume a human form. However, unlike other Gedounin who die out in a few years, Fuwa endured over the centuries and thus is condemned with an insatiable urge to find an ideal opponent, a fellow samurai who strays from the teachings of bushidō, to clash blades with. As a result, Fuwa mistakes the blade's cries of sadness for an equal lust for battle, believing that the souls of his family have lost their desire to stop him after he entered the Sanzu River.

He finds this opponent in Takeru Shiba, after witnessing his sword fighting as Shinken Red. This obsession with fighting Shinken Red leads Doukoku to seal Fuwa's Gedoushu powers, leaving him for dead in the Sanzu River. Although he barely survives with Dayu's aid, he continues to defy Doukoku by making sure that Takeru is at his strongest for their next fight, even curing him of Shitari's poisoning. After a long battle in which he manages to severely wound Shinken Red, Fuwa is defeated and falls off the cliff into the ocean below. However, Fuwa survives with Uramasa's blade snapped in half. He remains in the mountainside until Dayu finds him and relays Akumaro's offer to work for him in return for restoring his blade. To his chagrin, he has to rely on the replacement Bantō Dokuhōmatsu that hampers his normal fighting style. Later fed up waiting for the Uramasa to be repaired, Fuwa confronts Akumaro and learns his weapon's origins and that he is a pawn in Akumaro's plan. However, tricking Akumaro into giving him back his weapon and cutting him down, Fuwa reveals he knew the truth behind Uramasa from the first time he held it, thus preventing Akumaro from fulfilling his plan. Later, after the real Shiba House head is revealed, Fuwa gets Takeru to duel him once again before finally falling to him in battle with a delayed hit after Uramasa finally stops its master and denies him his only desire. Uramasa remains in the physical world after Fuwa fades away until the souls that formed it are finally able to depart into the afterlife.
Fuwa is portrayed and voiced by Mitsuru Karahashi.

Akumaro

Akumaro Sujigarano is an Ebisu/shachihoko/crocodile-themed Gedoushu general with six slit eyes and rictus grin, whose ambition is to see Hell and savor the immense suffering that it holds. Akumaro's modus operandi is to set up far-reaching plots with dangerous consequences that would ultimately result in the completion of the Urami Gandōgaeshi, a spell that opens up the gates of Hell. To that end he needed a Gedonin, killing off Juzo's family to create Uramasa and setting up his descent into Gedou.
Having battled the original Shinkengers in the past, they left him immobilized at the bottom of the Sanzu River. But when Doukoku's power burst revives him, he offers his services to Doukoku as gratitude. However, Doukoku strikes him near his left shoulder, ultimately creating a vulnerable spot. While pretending to aid Dokoku's group in raising the levels of the Sanzu River, taking any abuse from Doukoku to keep up his act, Akumaro starts setting up markers and recruits Juzo and Dayu into his service to make use of them. Eventually found out to be using Doukoku for his own agenda, Akumaro falls back after Doukoku nearly destroys him. However, with Doukoku resting, Akumaro takes the Rokumon Junk as his own while making the finishing touches on his master plan by completing the final marker to open up Hell and finishing Uramasa's repairs. Although he comes close to his goal, Akumaro is left with nothing when he realizes Juzo can not complete the Urami Gandōgaeshi and goes into an enraged fury before the Shinkengers use the Rekka Daizantou and Super Mougyu Bazooka to slay him. After becoming a giant, Akumaro battles the Samurai Giants and DaiGoyou with his Kirigami before SamuraiHaOh uses the Kyoryu Origami to form Super SamuraiHaOh and destroy him, with Akumaro laughing as his desire to see Hell is finally granted with his death.
A master of the black arts, Akumaro can create monsters called Kirigami and teleport short distances to catch his opponents off guard. He also uses his iron claw hands, Sakushin Dantō Shaku, and kemari as weapons.
Akumaro is voiced by Ryō Horikawa.

However, he is revived by Doukoku along with his followers during the summer-time and offers to kill off the Shinkengers for him with no intent on ruling the mortal realm. With his massive army, Manpuku overwhelmed the Shinkengers until Shinken Red breaks the seal on the Kusare Gedoushu's body to restore the Dinosaur Disk to its full power. After being slain by the primary Shinkengers, revived as a giant as he opens up into his true form with a serpentine creature sticking out of his stomach, Manpuku is destroyed by Kyoryu ShinkenOh.
