Why Does Nobody Remember Me in This World?

A high-octane shounen series blending action-fantasy survival with harem romantic comedy. Adapted from the light novel by Hosamine Kei, the TV anime is produced by project No.9, directed by Tatsuma Minamikawa, with series composition by Satoru Sugisawa. Featuring Kai Vento alongside Rinne and Jeanne Anise, the series delivers a dynamic mix of pulse-pounding fantasy battles and lighthearted romantic moments, appealing to fans of both adrenaline-fueled adventure and charming ensemble casts.

Why Does Nobody Remember Me in This World? is set in a world where humanity once emerged victorious from a devastating war, with the protagonist Kai Vento serving as a guardian of sealed crypts that contain the remnants of their defeated enemies. Everything changes when a mysterious phenomenon known as "World Rebirth" rewrites the very fabric of history, pulling Kai Vento into an alternate reality where the outcome of that great war was completely reversed — humanity never won, and Kai Vento himself has been entirely erased from the memories of everyone he once knew. Stripped of his identity and cast into an unfamiliar world that should not exist, this forgotten hero must find a way to navigate a reality where he is a stranger to all. With the world's balance hanging in the unknown, Kai Vento's journey to reclaim his place in history begins.
