Eiyuu to Majo no Tensei LoveCome

Choose the world, or choose her. Shiraishi Godo is just an ordinary high school student… or so it seems. In truth, he carries the memories of a previous life—one where he was a "hero" who once saved another world from destruction. But that life is behind him now. Determined to live peacefully in this world, Godo settles into a normal student life—until a mysterious transfer student, Mai Shiina, appears and disrupts everything. With her arrival, the boundary between past and present begins to blur, forcing Godo to confront an impossible choice: protect the world once more, or protect the girl who’s come to mean everything to him.
