Terumiu

Terumiu is the het ship between Miu Iruma and Teruteru Hanamura from the Danganronpa fandom.

Canon
Miu and Teruteru have never canonically interacted, as they both come from two different entries in the series. However, they do interact with each other quite frequently in Ultimate Talent Development Plan, and appear to be really good friends.

During one event, Miu and Teruteru are hanging out together in the dining hall, when they suddenly come across Hiyoko Saionji. Hiyoko becomes annoyed from the vulgarity of Miu and Teruteru's perversion, and a quarrel quickly breaks out between the two girls. However, because she is a masochist, Miu becomes ecstatic over Hiyoko's insults towards her. While Teruteru also becomes riled up from the fight between the girls. This disgusts Hiyoko even more, who says she wishes she could erase them both from existence. Teruteru responds by asking if she doesn't think that he and Miu are in sync. Miu says that he is way too small to satisfy her, but compliments him by saying he can whip up a decent meal.

During the fall school festival, Miu invites Teruteru to her exhibit. Teruteru comments that he is impressed by her "kinky" inventions, and then lewdly states that just thinking about her face while she made them is making his lions swell. Teruteru is then punched by one of her inventions, and Miu explains that her invention will punch anyone who says something unfunny or perverted. She then proceeds to make a perverted comment herself, and also gets punched.

During another event, Miu tells Teruteru that she has something for him out of sheer gratitude. Teruteru asks about it while mentioning that he was thinking about her. He seems impressed by her inventions and says that only she could create such a vulgar variety of pervy products. Miu responds by saying that even a pig like him can sniff out how amazingly talented she is. Teruteru encourages her to come get him when she invents another great product, and in exchange, he gives prepares Christmas dinner for her.

Fanon
The ship sailed due to both characters having a perverted personality. Being known for making situations awkward with their lewdness, which seemingly has no bounds. Their interactions in Ultimate Talent Development Plan was also likely a contribution. Both are also known for being extremely passionate about their talent, and often wish to show off their skills whenever they have the chance.

The ship isn't popular in the fandom, as both characters have never canonically met. Additionally, Miu has several other ships that are way more popular, while Teruteru ships tend be unpopular in general.
