After Junko and Akuto reconcile, he accidentally knocks Kena unconscious during a mana control lesson. Mitsuko suggests Akuto enter the mental discipline chamber, a location rumored to be fatal. Although Akuto feels depressed, Korone and Kena accompany him, leaving him caught between the two girls. Inside, they discover a mysterious map that Kena suspects is a treasure map, though Fujiko recognizes its true nature. The following day, Kena distributes copies of the map throughout the academy, causing students to injure themselves while searching for the treasure. As a disciplinary committee member, Akuto urges everyone to stop the search. However, a girl named Eiko Teruya appears, forcing Akuto to take responsibility and find the treasure himself.
