Kingo Yonekura

Kingo Yonekura (米蔵金吾, Yonekura Kingo) is a student at Binan High School who recently transferred into Ichiro Dougo and Taishi Manza's class due to his father's work, which involves looking for buried treasure. Part of the kanji for his name can be read as "Maizou Kin," a term for buried treasure. Being named after the thing that keeps his father so busy and away from home causes Kingo great suffering, and a darkness forms in his heart. This darkness allows Edelstein to turn him into the Buried Treasure monster. As a monster, he has the design of a wooden treasure chest decorated with oval coins and talks about buried treasure, muttering the onomatopoeia for coins clinking together. He also wears a loin cloth with the kanji for "gold" (金) on it.

Appearance
Kingo has short, neatly styled brown hair with his bangs parted to the side. His eyes are brown, and he wears a pair of half-rimmed glasses. Kingo wears the standard Binan High School uniform.

Personality
Due to the trauma of his mother abandoning him as a child over his father's work, Kingo absolutely hates the relationship between his given name and the idea of treasure. Although he dislikes the fact his father spends so much time looking for treasure, he still loves his father and defends him. Even so, he carries resentment in his heart over his father's absence, which allows Edelstein to take advantage of him and turn him into a monster. After Happy Kiss returns him to a happier state, Kingo realizes that his father may love his job, but that he has also been working hard to provide for him.

Quotes
"Once, he used the money he made on a treasure-digging job to buy me a toy."
