Comedy/TV/High School/Martial Arts Titles

In the Kanto Plain of Japan, high schools in the area are little more than fronts for what appear to be nothing more than gangs who all wear a strange earring. Within these schools, students fight to be the top-rated fighters in order to represent their school at the very unofficial Great Fighter's Tournament. However, what appears to be nothing more than thugs fighting street battles is in reality ancient Chinese history coming back to replay itself in modern times with students having names of various warriors from that time.

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.
