Sairin Yuusha no Fukushuutan

Iori Amatsuki was an ordinary high school student when he was suddenly summoned to a parallel world and chosen to become a Hero. In this new realm of magic and monsters, he dedicated himself to protecting the kingdom and its people from the encroaching darkness. However, after experiencing the harsh realities of war and the complexities of human nature, Iori finds himself at a crossroads. When he is unexpectedly given a second chance in this world—summoned once again to a future timeline—he must confront not only the ongoing threat of the demon king but also the shadows of his past. In this new era, Iori encounters unexpected allies, including a mysterious girl with her own hidden agenda. Together, they navigate a world where the lines between hero and villain have blurred, and where the true nature of justice and revenge becomes increasingly unclear. This is a tale of a young man's journey through betrayal and redemption, as he struggles to find his true purpose in a world that has changed dramatically since his first arrival.
