The first time they interacted, Mondo lunged at Byakuya for making Chihiro cry. Mondo seems to hold a protective side, especially when it comes to (since he thought Chihiro was a girl) girls, and stood up for him.

The next day, Mondo accidentally shouted and caused Chihiro to cry. Mondo immediately apologizes and promises not to shout again. In hopes of gaining strength, Chihiro would later ask Mondo to train with him, revealing that he was male and wanting to change from being weak to strong.

Mondo, feeling jealous of Chihiro's inner strength in comparison to his own, killed him in a blind rage, with the use of a dumbbell. Mondo soon regretted his actions and attempted to make it up to Chihiro by keeping his secret for as long as possible by switching the crime scene to the girl's changing room and by breaking Chihiro's e-Handbook in the sauna so his gender wouldn't be revealed. Mondo is later executed willingly by Monokuma after being discovered as the culprit.

Sometime after Mondo and Chihiro's deaths, the remaining survivors found a high school picture of the two laughing with Leon, possibly meaning that the two were friends prior to the Tragedy. In Danganronpa 3, Mondo is shown working with Chihiro to help seal up the school.
