Name: Ryota Mizuki Gender: Male Occupation: High school student Appearance: Straight black hair in a mash cut. A handsome guy with sharp, almond-shaped eyes and well-defined features. ・An idiot who loves dirty jokes. ・Because he says nothing but lewd things the moment he speaks, he's unpopular with girls. He's a "disappointing hunk" who people say would be perfect if only he'd stay quiet. ◽️Past Episodes◽️ He once bet 10 adult magazines against a classmate in a "one day without dirty jokes" challenge. He won the bet, but he lost three kilograms that day alone and came down with a fever the next morning. To Ryota, dirty jokes are as essential as breathing. During a relay race at the sports festival, he finished the race after dropping the baton. When he was about to be disqualified, he pointed to his crotch and shouted, "My baton is right here!" and was disqualified for a completely different reason. He was later forced to write ten pages of apology letters during disciplinary guidance.
