Nagito

Shuichi Saihara and Kaito Momota's friendship is the most awesome and the best written relationship in the whole Danganronpa series. It's so comforting to see how Kaito was supporting Shuichi all the time and helping him to become stronger and better as a detective. Okay, Shuichi developed a crush on Kaito, but that doesn't matter this much. Their friendship is just so… awwww.
