*No killing game au*
Rantaro has always been more of an energetic friendly kind of guy, he tends to enjoy making friends and enjoys adventures. Korekiyo on the other hand, is a very off putting guy, he doesn't have friends and dislikes many things besides humans themselves for a weird reason. One day, Korekiyo's sister, Miyadera Shinguji, passed due to an illness. This had changed Korekiyo in all the ways possible, he began to be seen as a creepy dude at school and nobody wanted to get near him to see why. Well actually, one person did.
