Synopsis: Wonder School Boy

Tsubaki Tenji is an ordinary high school student by day but a remarkable detective by night. He pretends to be a clumsy and foolish teenager among his peers, but he's actually nimble and quick-witted with extraordinary martial skills, using only 500 yen coins as his weapon. Tsubaki isn't motivated by the thrill of the chase; he's on a quest to pay off his father's debt, who disappeared suddenly. At the Muroto Investigative Agency, he works for the eminent Muroto Shino and with his sister Yuki. Tsubaki's challenging nocturnal pursuits exhaust him, but he's extremely cautious not to expose his double life to his classmates, fearing expulsion from school if caught.
