Riki Nendou (燃堂 力, ねんどう りき lit. Nendō Riki) is a dutiful and dull-witted boy. He likes helping people and prioritizing the weak. Riki is one of the main characters of the series and was starred by Arai Hirofumi in the live action of the series.

Appearance
Riki is evil in appearance and sloppy in behavior, and thus avoided by his classmates. His defining physical attribute is the scar on his left eye, something that can be used to differentiate between him, his father and mother who all have the same faces. His hair is cut in a weird way with his bangs colored yellow while the rest is black. In school, he wears the standard PK Academy uniform but keeps his uniform open showing a t-shirt. Outside the school, he mostly wears collared shirts.

Personality
Riki's dominant traits are his apparent lack of intelligence and the scar on his right eye. Despite his looks, he is actually pretty weak. He is usually idiotic in manner and typically needs things to be explained to him countless times but he still cannot understand it.

However, despite his villainous face and actions, Riki was a kind man which Kusuo himself thinks that only the latter thinks so as Riki would usually be judged by others as a delinquent boy. This kindness was seen when he rescued a girl who rejected him from drowning and accepted her apology for harshly turning him down, at the same time he saved Kaidou Shun and Hairo Kineshi. Due to his past as an owner of a hamster, when he got Kojikara No. 2 from Kusuo, he showed a great deal of patience and care to the hamster and the two got along so well he would sometimes take it with him to school.

History
When Riki was a freshmen, he was introduced as a bully that constantly picks on Kusuo and copies his notes. He later changed and became Kusuo's stalker after thinking that Saiki was the one who saved him when he was framed by Takahashi. Later that day, Riki became a protector of Kusuo, scaring any people passing by Kusuo and constantly pesters Kusuo to eat ramen once school ends. In a time skip, Riki was a sophomore along with Kusuo and Shun and the three are grouped together with Kusuo seen in center, the students thinks Kusuo is the leader of their group.
