High School DxD: True Longin

Once opening his eyes, the young guy discovered that he had been reborn in the body of a small, recently born child, and on top of everything else, he also got a sister. And the world in which he is now forced to grow up again turned out to be a place where, in addition to people, there are also a myriad of different creatures and species.

Gods, angels, fallen angels, demons, vampires, youkai, and even noncomat cat girls.

Being an ordinary weak person, he saw only one way how not to become an accidental victim of the showdown of supernatural creatures – to gain his own strength. This is the beginning of the path of a person who refuses to accept his weakness and will do everything possible to climb to the top of the food chain of this new world for him.
