In the Kemono series' eighth installment, Kazuki, the Toudou Group's youthful heir, is on a journey to leadership. His father is mentoring him to take over the company, but his twelve-year instructor Chiharu snaps and takes matters into their own hands, following Kazuki's father's orders. Chiharu and Kazuki end up romantically involved, but as Chiharu's mental state deteriorates, it begs the question of how far they'll go, and if Kazuki can handle Chiharu's increasingly wild nature.
