Nitroplus


Nitroplus Co., Ltd., currently stylized as NITRO PLUS, formerly stylized as nitro+, and formerly known as "OKStyle", is a Japanese visual novel video game developer that has developed a number of visual novels, including eroge. They have also collaborated with developer Type-Moon to create the light novel series Fate/Zero. Their works usually have dark themes such as reanimation of the dead, rape, and murder. They also have a branch of the company called Nitro+chiral, which focuses on boys' love visual novels. Writers aligned with the company, such as Gen Urobuchi, have also contributed to various manga, anime, novels, and television works.
Super Sonico is the mascot of Nitroplus's annual music festival event "Nitro Super Sonic" since 2006. Nitroplus has held their music festival every year since 2000. Ouka Satsurikuin was Nitroplus's original mascot before Super Sonico.
In June 2024, Nitroplus announced that CyberAgent acquired 72.5% of the company for 16.7 billion yen, making it a subsidiary.
CyberAgent published a public relations interview about Nitroplus' decision to become a consolidated subsidiary, stating that Nitroplus approached CyberAgent for the merger after the company acquired Nelke Planning a year prior, which Takaki Kosaka, the representative director of Nitroplus, had a stake in as an independent director. The primary goal of the acquisition is for CyberAgent to take over the administrative and distribution aspects of the business so that Nitroplus can focus on content production, including reviving projects that were abandoned due to time constraints or lack of resource management. There are also plans for this partnership to help Nitroplus expand its influence overseas and strengthen the Touken Ranbu brand. In a follow up statement released on their company website, Nitroplus went on to clarify that the type of content produced by the company will not change, only the quality and quantity of the content.
