Nanana's Buried Treasure

After being disowned by his father, Juugo travels to the artificial island of Nanaejima, also known as the Special Student Zone.

Juugo obtains a jewel while on his way home from the convenience store that turns out to be from Nanana's collection.

Juugo, Tensai, and Daruku become members of the Adventure Club and search for treasure in a shopping complex called Rising Building.

After distracting Tensai with the fake kidnapping, Juugo teams up with Yukihime to steal the Wizard Cane back from Yuiga.

Isshin proposes that they plan a trip to a hot springs town on the west side of the island, where he thinks they'll find the next ruins.

The Adventure Club arrives at the hot springs town; in the hallway of their inn, Juugo sees Yukihime with a friend of hers, but she ignores him.
