The Crimson Oni Mask

Josuke Hachimizu, a 20-year-old manga artist, has achieved the kind of success most people only dream of: anonymous fame, a life of comfort, and a brilliant career. Yet behind the glass walls of his sleek apartment, his life feels empty—trapped in the monotony of a world that no longer inspires him. Everything changes one night when a chilling and unexpected encounter with his long-lost sister drags him into a fate he never imagined. Marked by a crimson mask of unknown origin—an ancient, living relic—Josuke awakens in a foreign world, governed by power, magic, and a system that labels him as a mere “Level 0.” Now, forced to survive in a land where many seek to steal the Crimson Mask, Josuke must face not only those who desire its power, but also the weight of his buried family scars, a silenced past, and the burden of a legacy he never asked for. As the gears of fate turn mercilessly, Josuke fights for more than the salvation of a world: he fights to find a place where he can finally be free… and the author of his own story.
