Crossover Anime World: Reborn as Abe no Seimei

Synopsis After transmigrating into a supernatural crossover world of anime and manga, Gin finds himself in a modern age where order is collapsing and the boundary between day and night has been rewritten—humans rule the day, while yokai dominate the night. In this dangerous new reality, he awakens a role-playing system and begins with the identity of the legendary founder of Onmyodo, Abe no Seimei. As his power grows, the entire supernatural world is thrown into chaos. Shuten-doji trembles in fear. “How can Abe no Seimei still be alive?!” The Onmyoji world is shaken to its core. “The founder of Onmyodo... has returned in the modern era?!” Hagoromo Gitsune gazes at him with motherly affection. “Seimei... my child, so you really have reincarnated...” Tamamo-no-Mae grits her teeth in hatred. “Abe no Seimei... my mortal enemy!” And as figures like Tsuchimiya Kagura, Eriri, and Shinomiya Kaguya are drawn into his orbit, Gin Tsumugi must rise in a world where monsters, curses, and ancient legends are returning one after another. In an age where darkness devours the night, can he truly become the modern Abe no Seimei—and stand above both humans and yokai? — Description from novelcodex.org
