Isekai Shoukan wa Nidome desu

Once a hero summoned to another world, Touya defeated the demon lord and brought peace to the land, only to be unceremoniously sent back to his original world with his memories wiped clean. Now, years later, he’s living a perfectly ordinary high school life when, in a cruel twist of fate, he's yanked back to the very same fantastical realm he once saved. The catch? He's still got his immense power, but this time, he's a completely different person. This second summoning throws Touya into a world that has significantly changed since his last visit. With old alliances fractured and new threats emerging, he must navigate political intrigue and burgeoning conflicts, all while grappling with the lingering echoes of a past he can't quite recall. Prepare for an action-packed adventure filled with aerial combat, unlikely allies, and a healthy dose of collateral damage as Touya attempts to unravel the mysteries of his dual existence and, perhaps, save this world all over again.
