Synopsis
Setting
Fate Rewinder centers around the "Space-Time Police Special Forces", a secret order of time travelers serving to prevent catastrophes on a larger scale across time and space itself.Operating from a dilapidated building in the year 2087, they send special agents called "Rewinders" to undo the deaths of their designated targets by repeatedly utilizing their "Retry Eye", an eyepatch-hidden prosthetic right eye with a built-in time machine that allows its user to rewind time and use prior knowledge of the events that transpired to avert a doomed target's demise. It can also revive recently deceased Rewinders, though at the cost of those revived Rewinders having their memories of the prior loop wiped clean, necessitating the importance of bringing them up to speed on the task at hand. A major drawback of repeatedly using one's Retry Eye is that its user starts suffering psychological damage and physical exhaustion with each successive use after rewinding more than a hundred times. Furthermore, damage to the Retry Eye may occur through various methods, which could make it inoperable unless it is repaired in a timely manner.
Additionally, in certain cases, a Rewinder's Retry Eye might awaken its full potential in the form of "Version Up", a special ability unique to each Rewinder that grants limited access to a particular aspect of space-time itself, albeit with caveats that restrict it to at most a single use per loop.
Given the complex nature of a designated target's death and the circumstances leading to it, a Rewinder's mission can quickly turn into a war of attrition, necessitating the completion of their objective by any means before their body gives out under psychological and physical strain. The unit employs a ranked system to classify mission difficulty, with the prestigious “SS Grade Rank” reserved for the most complex cases, such as the infamous "Case 999", of which no Rewinder has ever successfully solved so far.
At times, the Space-Time Police Special Forces frequently clashes with the “Clock Hands,” a notorious criminal organization that wields time-traveling technology for illicit purposes and disrupts the Rewinders’ operations.
Plot
After a personal tragedy that took something from him, a young boy named Chrono is inducted into the Space-Time Police Special Forces Unit as its new Rewinder, under the mentorship of Shirai, a former Special Grade Rewinder. Shirai, who lost his ability to rewind after a traumatic event damaged his Retry Eye, trains Chrono for several years. With his Retry Eye, analytical intuition, photographic memory, and an inhuman mental durability, along with the aid of his sentient flying smartphone, "Smartphone," 14-year-old Chrono rises through the ranks, aiming to solve "Case 999", an unsolvable case involving the death of his sister, Tokine, and a member of the notorious "Clock Hands" terrorist organization.In the process, he have made numerous allies as he working alongside them in various missions: Akaba, a katana-wielding 16-year-old Rewinder and self-professed disciple of Shirai; Lemon, a monotonic 12-year-old gynoid; and Chainu, a meek and timid 18-year-old Rewinder with a mysterious past. Together, they tackle various cases of increasing complexity as Chrono often coming into conflict with the "Clock Hands", whose members are constantly hindering their mission and preventing Chrono from rising up the ranks and tackling "Case 999" for reasons beyond everyone's understandings.
