Plot

On the "Special Student Zone" artificial island – Nanaejima, the story centers on a beautiful, optimistic, but NEET (not in education, employment or training) girl Nanana Ryūgajō, who was mysteriously killed in her own apartment.

Ten years later, a boy named Juugo Yama was forced to transfer to a high school on the island. With only a certain amount of money to live on, Juugo chooses a low-rent apartment that happens to be haunted by the ghostly Nanana, who is bound to her former home and unable to move on. Juugo and members of the school's adventure club join a "treasure hunt royale" on the island for the Nanana Collection, a treasure that possesses a mysterious power.

Jūgo Yama (八真 重護, Yama Jūgo)

Voiced by: Yūki Ono

The male protagonist. Juugo is energetic with a strong stamina, and has a favor to girls (especially maids). He is devoted to helping Nanana move on, in spite of her constant commotion in his room, as he tries to find interest in her. Juugo joins the school's adventure club on a hunt for the island's Nanana Collection. It is revealed he's secretly the heir of Matsuri, an ancient "noble" thief organization that claims to only steal from the wicked, but was banished to Nanae Island when he refused to take the position due to a difference in ideals. Juugo does not believe in doing things for others, and does not believe he'd give everything to help anyone. Despite refusing to take the position, Jūgo is actually quite good at stealing treasures, and managed to outmatch Tensai, Isshin, and even other Matsuri members a few times, although Tensai usually deduces it in the end. Jūgo's Nanana Collection is a large jewel that allows its user to see others lying when looking through it, which originally belongs to Ikkaku, but Jūgo intercepted it when Matsuri members attempted to steal it, and gave them a fake one later.
