An elementary school boy on inline skates dubbed Lil' Slugger (Shōnen Bat in Japanese, meaning "Bat Boy") is said to be responsible for a series of mysterious street assaults in Tokyo. None of the victims can recall the boy's face and only three distinct details are left in their memories: golden inline skates, a baseball cap, and the weapon: a bent golden baseball bat.
Two police detectives, Keiichi Ikari and Mitsuhiro Maniwa, are assigned to the case to track down the perpetrator and put an end to his crimes. Starting with the first victim, Tsukiko Sagi, a shy character designer who created the immensely popular pink dog Maromi, the detectives follow what little clues they have and try to apprehend the mysterious boy. Just when they think they have solved the case, new evidence about the attacker leads them towards a frightening revelation.
Lil' slugger was eventually found out to be an excuse made by Tsukiko after her dog died. She blamed the fact that she accidentally killed her pet dog Maromi on a fictional boy wearing gold skates and a baseball cap. Lil' Slugger is actually a paranormal figment of Tsukiko's guilt and fear.
