In the final battle, the Hashira all died to protect me. When I woke up, I had returned to the past.
About
──I will never forget that day. The final battle against the demons. To protect me, the Hashira fell one by one. In the end, I was the only one left. When I woke up in the depths of despair, I was back before it all began—the daily life of the Demon Slayer Corps. However, I couldn't simply rejoice. Before my eyes were the living Hashira. And yet, not a single one of them remembered me. Sanemi's cold gaze. Iguro's wariness. Giyu's distant demeanor. The bonds we built and the promises we made up until that day have become memories belonging to me alone. Still, I know. I know that in the future, these people risked their lives to protect me. So this time—I will protect everyone. For a future where not a single person is lost. The lonely battle to rewrite fate begins.
