Previous to coming to Hope's Peak, it was common knowledge to everyone that Daiya, Mukuro, and Junko were in a relationship. It was also common knowledge that Mukuro was agender, and while most people were respectful about that kind of thing, some still thought it wise to challenge Mukuro by saying something stupid to zem. Sometimes, the perpetrator decided to say something stupid when Daiya was around, which was an even stupider move to make, as if there was one thing Daiya hated more than cold puppies, it was disrespect when it came to pronouns.
Which, of course, leads us to our current predicament.
"So, if you're a girl," said an obnoxious first-year who went to Mukuro's high school, "then how come you use those dumb pronouns."
"I'm sorry," ze laughed as ze flicked out zir handy dandy hunting knife and began to file zir nails with it, "I can't hear you over the sound of my knife."
"And my boyfriend running you over."
Of course, that statement was then accompanied by the roar of a motorcycle, and Daiya slamming on the breaks just before running the kid over on his shiny black devil. Which caused the kid to pass out, but nobody noticed that.
"Sorry I'm late," Daiya crowed over the sound of his engine, "I didn't kill him, did I?"
"No, he's alive, unfortunately. And you were just in time, love. Now where's that sub I asked for?"
And all was normal in Daiya-and-Mukuroland.
