It's Sana versus Hayama in a battle for control of the classroom! But when she finally wins things don't go quite as expected and she finds herself closer to trouble maker Hayama then she ever expected...

High School student Shinichi Kudou was a virtual Sherlock Holmes, who the Tokyo police regularly turned to for help in solving baffling cases. But then he accidentally learned too much for his own good about a murder case, and was caught by the villains. They poisoned him and left him for dead, but the "poison" had an unexpected effect--rather than killing him, it caused Shinichi to revert to the appearance of an elementary school boy! He retains his skills as a brilliant detective, however, and since that incident has managed to become adopted by his former girlfriend and her less-than-exemplary private detective father. With them he carries on his passion, and searches for clues to a possible antidote to the poison he was forced to swallow.
