Isekai Shoukan wa Nidome desu

A former hero, once lauded for saving an alternate world, unexpectedly finds himself back in his original world, starting life over as a baby. Now a gloomy high school student, he feels out of place until an unexpected twist of fate resummons him to the world he previously rescued. With memories of his past heroics and the knowledge that this is his second chance, he is ready to face the challenges ahead.

This second summoning opens up a path filled with old threats and new allies, as the world has not remained static in his absence. As he reacquaints himself with this familiar yet changed realm, the protagonist leverages his unique position as both a veteran and a newcomer to navigate the complexities of his role. His journey promises not just personal redemption but also a chance to reestablish his legacy in a world that has both revered and moved beyond his former deeds.
