Ishimondo

Ishimondo is a slash ship between Mondo Oowada and Kiyotaka Ishimaru in the Danganronpa series.

Canon
Mondo and Kiyotaka did not get along at first, which was not surprising, as Kiyotaka was the “Ultimate Moral Compass”, while Mondo was the “Ultimate Biker Gang Leader”. They formed a rivalry, which quickly escalated to the two spending a prolonged period of time in a high-temperature sauna. This was to show a test of manliness and strength, and whoever were to give up would be the lesser man.

However, as soon as this event was over, the next morning Mondo and Kiyotaka acted as if they had been seemingly inseparable. They would laugh together and have their arms around each other's shoulders in a “friendly” manner.

When Mondo was found guilty in the second trial, the only person who did not vote him as the culprit was Kiyotaka, who voted for himself instead. With this, it seemed like Kiyotaka was willing to have himself and everyone else die before he would let Mondo himself. He broke down, bawling and screaming, yelling and asking why he did it, clearly devastated that he was losing such a close friend.

During the third Chapter, when Kiyotaka was speaking with Alter Ego, the program changed its appearance and attitude to match that of Mondo's. Through Mondo's inspiring words, Kiyotaka then went through a self-proclaimed “transformation”, in which his and Mondo's “spirits” became one. He started addressing himself as Kiyondo, which is a culmination of both his and Mondo's names.
