|Anime||Ryuugajou Nanana no Maizoukin|
|Alternate Title||Nanana's Buried Treasure|
Daruku is Tensai's assistant, where he and she maintain a sort of Sherlock Holmes and John Watson-type relationship. Though he may look very convincingly like a girl, it is revealed in the anime that he is a boy. Daruku and Tensai transfer to a school where they meet Juugo, the protagonist. During their brief visitation at Juugo's apartment, they meet Nanana, a ghost living with Juugo. Tensai is a member of the "Adventure Club," and because Daruku is constantly on Tensai's tail, he's considered a member of the club, as well.
