So there's this manga I read a while back and now I wanna continue but can't remember About the manga: Basically it's about these aliens or power holders that look like human kids. These aliens(or power holders) don't age so they look a kid forever. Their identity as aliens(or powerholders) can be discovered by people if they see their pubic hair because kids ain't supposed to be having pubic hair. The alien kids have their own territory .I think if 2 of them are in the same place, a fight takes place and winner keeps territory. The main character has a special power where whatever his blood comes in contact with will come to life I think I believe the title is like Chi- something Quite sure the manga title begins with a C maybe idk
