Itsuki and Mahiru performed their first Love Ritual. A "Star Child" that will be able to cleanse the Impurity was born, as they bonded through physical contact. Later, they were transferred to "Hoshigami Academy," where the "maidens of the 12 constellations," who will perform the Love Rituals with Itsuki, were gathered.
