[DASS-992] A completely defeated older sister. As a former undefeated MMA champion with a gentle and powerful personality, there's no way I'd lose to Bean Sprout Kid Kid. Hibiki Otsuki

Hibiki Otsuki, a former martial arts champion and now a full-time housewife. When he beats Yuto, a local troublemaker out out at night, in martial arts, he challenges him to a match with the words, "Do as you say!" Overcome with frustration after losing the match, Yuto secretly drugged Hibiki with an aphrodisiac and challenged him to a rematch. Hibiki loses to Yuto because of the aphrodisiac, unable to muster his strength. Hibiki challenges Yuto to a match again, but is told, "If you come, just do as I say," and continues to be made to climax by the aphrodisiac, eventually becoming a submissive slave.
