Shortly after they transition to the artist in his studio as two actual detectives, who look like Laurel and Hardy in Dick Tracy era suits and trench coats, knock on the door and appropriate Kevin's room for the purpose of conducting surveillance on a room in an adjacent building. One of the detectives, the skinny “Laurel”, sees Kevin's work and it turns out he's a Billy Bat fan. The other chubby "Hardy" detective picks up a page and says that the characters look familiar and accuses Kevin of translating an old "Jap" comic.
As Hardy remembers the comic he thinks Kevin is ripping off, the story jumps off to 1949 Tokyo.
Kenji and his old friends are slowly being drawn into a mysterious conspiracy that could threaten the world. Who is the mysterious "friend", and how does he tie into Kenji's youth? Why are there disappearances and deaths tied into Ochanomizu University? The friend's memories hold the keys to the puzzle, but years between cloud the clues.
The strange occurances and the reach of the "friend" conspiracy grow by the day. It will all culminate on New Year's Eve 2000. Will Kenji and the rest of the group be able to put together the puzzle and save the world?
