Set in a unique academy where "dual-gender coexistence" is the norm, all students are "hermaphroditic" beings possessing both male and female genitalia. Here, a lustful beast teacher and three students caught in the chaotic force engage in a passionate journey that crosses the boundaries between love and desire. The school harbors an invisible erotic entity known as "Chaos," which stirs the students' emotions and awakens their sexual impulses. It all begins the moment "Ai," with her massive breasts, seduces the teacher. Risa, Karin, and others are drawn into the frenzy, igniting an intense, school-wide web of relationships. Whether it's love or lust, no one can tell. A desire-filled school life begins now.
