Katsuo, an ordinary young man, is transported to a corridor between worlds during a storm. There, he meets Kira, a mysterious girl who reveals that the corridor connects countless worlds, each with a version of herself. But the corridor is filled with dangers, from monsters to unknown threats that may be far beyond his grasp. Now, Katsuo must choose between staying with Kira to find a way out or braving the unknown to return to his old life. In a realm where reality is unstable, he must fight to uncover his destiny.
Waking up in the body of a Romani Archiman is acceptable. Getting 3rd and 1st True Magics is nice. Getting Beasts as pets - delightful. The world of DxD is unforgivable. It's a world where some teenagers who aren't even two decades old somehow mystically defeat the descendants of legendary heroes, ancient demons, powerful dragons, etc. Why does this happen? Simply because! Simply put, this world only makes sense because it doesn't. And now, I have to put up with the fact that I live here. Such pain. (DxDxMulti)
