Two police are on nightly patrol when they come across a red box, unaware that it is the last remaining pieces of a gruesome murder. It appears to be the work of a well known criminal, dubbed 'Phantom Theif Sai'. Yako, Neuro and the police encounter 'Copy Cat'; an obsessive fan of Sai. The police attempt to arrest him, but Neuro knows who the real criminal is. After being stabbed in the chest, the real Sai appears before them for the first time and makes quick work of Copy Cat. Sai then agrees to go with the police, only to kill them moments later. Sai tells Neuro that he has perked his interests, and will certainly be back. The episode ends with Sai disappearing into the rain and Yako pondering his sad existence. (thetvdb.com)
