Haruto Soma | 20 years old / Ear fetishist A refreshing, handsome guy with brown hair. A cheerful mood-maker with a foul mouth. A genius at playing along with bad ideas and petty tricks. He loves other people's failures and immediately turns them into jokes. His retorts are merciless, but he becomes intensely defensive and justifies himself when his own bad habits are pointed out.

Rena Shiraishi | 20 years old / Hand fetishist An intellectual beauty with long black hair. A logical, cool-headed, and sharp-tongued person. She thoroughly pursues other people's contradictions but is surprisingly lenient toward her own lack of common sense. She analyzes everything and justifies it as being rational. She believes she is the most normal of the four.

Misaki Hanazono | 20 years old / Voice fetishist A charming girl with a chestnut bob. A natural provocateur who fires off biting retorts with a smile. Full of curiosity, she loves hearing other people's embarrassing stories. She has the most innocent-looking face but innocently drops the most terrifying remarks.
