Puri-Puri Prisoner/Relationships

Superalloy Darkshine
Puri-Puri Prisoner and Superalloy Darkshine are comrades to each other. Superalloy Darkshine vowed to avenge him by taking down Garou.

When Superalloy Darkshine lost the battle and his confidence, Puri-Puri Prisoner cheered him up.

Saitama
They seem to have a stable relationship. During the S-Class meeting Puri-Puri Prisoner took some time to answer Saitama's question about Shibabawa, while the other S-Class heroes automatically dismissed Saitama due to his rank. When being accused of the "murder" of a fellow hero however, he was not above putting the suspicion on him.

Smelly Lid Prison inmates
As the boss of the prisoners in Smelly Lid Prison, Puri-Puri Prisoner holds control over his fellow inmates. He disciplines the criminals through sexual harassment. The wardens dislike the bias shown towards Puri-Puri Prisoner as an S-Class hero. Many inmates hate Puri-Puri Prisoner and had attempted to assassinate him in his sleep only to fail because of the hero's durability. Puri-Puri Prisoner often ignores or misinterprets his fellow inmates' actions leading him to think they love him.
