Nomura Nobuo works part-time at a food store beside the pool. Every time someone agitates him, he draws stickers for them and puts their face up on his calendar chart. The person who reaches the top of the model in the calendar first will be sent to hell. There are two main candidates initially, the lady who lives near him and steals his bike-parking lot, and a random guy who impolitely takes the drinks from their counter without paying first. When he finds out his crush, Sasayama Kokoro, has a boyfriend, the boyfriend becomes another target to be sent to hell. In the meantime, his manga debuts in a monthly manga book, so although each of his victims in the calendar chart has reached "the point", he decides not to send them to hell since he is in a good mood. It is only when he sees Sasayama Kokoro trying to commit suicide because her boyfriend Ryuu, cheated on her, he decides to send him to hell. However, Nobuo is sent to hell by Kokoro, who believes that he will spread rumours about what she told him.
