Rins super strong, has great sword skills, powerful fire, and great friends to back him up. Despite being the half demon son of Satan, he is a generally great person and friend... he also has one MASSIVE previously unknown weakness.... he's EXTREMELY ticklish. One thing led to another and Shima has him in his boxers in an abandoned classroom in the Cram school. So far his bellybutton is his worst spot
