One day, his estranged stepfather Ryuji Sone (Kansai Yamamoto) suddenly returns home and begins to freeload off his family. After Shuichi encounters what appeared to be Sone making sexual advances towards Haruka one night, he tries to get rid of Sone. However, Shuichi discovers that it is impossible to do so legally. During his art class, he secretly returns home to a sleeping Sone. After thorough research and experimentation on electrocution, he carries out his plan and kills his stepfather. The police declares that Sone had died of natural causes. Shuichi continues his everyday life and begins seeing classmate Noriko Fukuhara (Aya Matsuura). One day, Takuya Ishioka (Yosuke Kawamura), a classmate who skips school and causes trouble, goes to see him at the convenience store where he works. Ishioka, who knows what Shuichi did, threatens to tell the police if Shuichi does not get him 300,000 yen (approx. $3,000 USD) in a week. In his room, Haruka reveals to him that Sone had been dying of cancer. Although Shuichi regrets his actions, in order to keep Ishioka quiet, he fools Ishioka into staging a robbery at his workplace. Shuichi stabs him, making it look like an act of self-defense. However, police officer Masashi Kano (Baijaku Nakamura), who also met Shuichi at the time of Sone's murder, finds flaws in Shuichi's claims and actions. While seeing Noriko home at the train station, Shuichi admits to her that he is a murderer. The police manages to uncover the truth of what really happened to Sone and Ishioka, but Kano lets Shuichi go home on the basis that he promises to willingly turn himself in the next day. After having breakfast as usual with his family and leaving a tape-recording for Noriko at school, Shuichi commits suicide. In his tape-recording, Shuichi talks about his favorite things. Noriko stops coloring her drawing of a future Shuichi blue to listen.
