Kuboyasu Aren/Relationships

Saiki Kusuo
After Aren transferred to PK academy he was alone. He tried to make friends with Kusuo, whom he sees as a loner. However, the latter didn't want to make friends with him, so instead he rebuked Aren, making him angry and causing him to show his true face. Aren admires that Kusuo has many friends, which he learned when he saw him being crowded by Kaidou, Nendou, Teruhashi, Chiyo and Toritsuka. Eventually, Kusuo accepts Aren as part of his "friend group."

Kaidou Shun
Kaidou was the second person to know about Aren's secret of being a former delinquent. He figured it out when he saw Aren with a group of delinquents, so Kaidou decided to never befriend him. He was scared of Aren, but later they become friendly with each other after Aren saved Kusuo and him from delinquents who tried to steal their money. Later on, they occasionally refer to each other by their given names rather than their surnames, indicating closer friendship.

Nendou Riki
Aren originally thought of Nendou as a strong rival or another delinquent after seeing his face, but later realized that Nendou is a moron. Even so, Aren still sees him as a friend, and tried to help Nendou make money to buy a gift for his mom. They bonded over how they both learned to cook because their mother's were always busy.

Hairo Kineshi
At first, Aren was put off by the Hairo's energetic nature and decided it was best to avoid him. However, when other classmates talked badly about Aren, Hairo stood up for him and gave a speech that sounded like Aren's old leader. This caused Aren to respect Hairo who became the first person that he wanted to be friends with.

Aiura Mikoto
Aren was shown to be not good with girls, as when he was hugged by and flirted at by Mikoto, he had hard time and was stuttering. Despite not believing in fortune-tellers, he got scared when Mikoto saw his mullet's aura and inferred tht he was a "strong, aggressive boy."

Saiko Metori
Aren is deeply annoyed by Metori’s smug and egocentric attitude. Metori often provokes him to anger both intentionally and unintentionally. Despite this Aren has shown to care about Metori and his well-being.
