The world is never quite the same once we grow up. Villains and robots that once ran rampant in our imaginations are reduced to drawings in Manga, and our lives are distilled until there is little left but the daily grind; so it has been for Kenji. After a childhood of dreams, he now runs his late father's liquor store and is raising his sister's child. The memories and friends from his early years bring him some happiness, but they become tainted as a string of murders find connections to his past. Kenji and his friends must now fight to save the future from their past and unravel the mystery of "Friend."
