NextNinja

NextNinja Co., Ltd. is a Japanese mobile game developer and operator whose company motto is IDEA OF INFINIT. It has built a strong reputation for anime-inspired mobile RPGs, with a lineup that includes Grand Summoners and Touhou LostWord as well as a Gintama-themed command battle RPG. NextNinja’s lineup includes Gakuen Bungo Stray Dogs, an upcoming mobile adaptation of the popular Bungo Stray Dogs anime and manga. Unlike the gritty supernatural battles of the original, this spin-off reimagines the cast as students and teachers at Sakurashin Academy, where a forbidden encounter leads into a surreal alternate world called I-kai. The project mixes slice-of-life humor with mystery and has already surpassed 250,000 pre-registrations in Japan. It showcases NextNinja’s familiar strengths: faithful anime visuals, character-driven storytelling, and polished mobile RPG systems.
