Michiko finishes the script, and Yuuko selects her to be the director of the play. As a result, she assigns the actors' roles, and Mari is uncomfortable in her part, especially after Hagino acts her part seemingly perfectly. Afterward, everyone in the dorm helps in preparing the props for the play, and Hagino, inspired by Michiko's statement to have the courage to be open, invites Mari onto Blue. After the two enjoy a ride, the ship begins to suffer system failure, and Azanael takes Mari away. However, Azanael reveals that Hagino was responsible for the deaths of everyone in the incident five years ago, including Mari's parents. As Azanael escapes, Mari stares blankly at a tearful Hagino.
