The story starts on April 21st, with him narrating the story. He was prisoner number 420; and briefly talked about the existence of "happy ends" negatively thinking about the world. Number 420 (his real name is not yet revealed nor will it ever be, for everyone addresses him as number 420) was then led to his cell by Kaimural (Kaito) where he found a blanket and walls of ceramic. Two new (non-vocaloid) characters were introduced, Rythm Garcha and Shazna Ivory; with whom tried to hurt number 420 to the point where he's shown to cry.
