第 4 集: Akuto、Kena 和 Korone 探索危險的精神修練室與神秘地圖

Kena's intervention manages to somehow make Junko and Akuto friends again, but during a class lesson on mana control, he knocks her unconscious again. Mitsuko recommends that he go into the mental discipline chamber, one where people are said to have died. Akuto gets depressed, but for some strange reason, Korone and Kena tag along and he is caught between the two of them. They find a mysterious map and Kena is intrigued, wondering if it is a treasure map. Fujiko recognize what the map truly is. The next day, Kena copies the map and posts it all over the school. It becomes the talk of the whole academy, because students keep getting hurt as they try to find the treasure. Akuto, in his role as the disciplinary committee member, insists that they give up looking, but a girl named Eiko Teruya suddenly appears and he ends up having to find it himself.
