Kizuguchi to Houtai

Kiritani, second-in-command of the Kurotorikai yakuza organization, is handed the job of looking after Riyo Washizu, daughter of the Washizugumi's grand chairman. Riyo seems compliant enough that he expects an easy assignment, until he learns of her particular taste, called Yowaraa: she is aroused by the sight of strong, formidable people reduced to helplessness. The series plays their arrangement as a romantic comedy between the yakuza heiress and the man assigned to mind her.
