Not a Hero, Not a Villain (Undertale x My Hero Academia)

Chapter 1

Birds chirped as pupils peaked out from under a turrent of white hair. They stared deathly at the wooden desk, lightly groaning as Sans dragged himself up from his nap.

He was in the teachers facility room, in his assigned desk besides Aizawa's. Or, as he called him on a few occasions, Eraser top. The reason behind Sans' awakening wasn't natural, no, as a ruler had been lightly smacked against the back of his head.

"The students will be coming in ten minutes," Aizawa said, laying a brown paper bag next to Sans' head. "And my wife made you lunch."

"Heh," Sans muttered, sitting up in his chair and lightly rubbing his eyes. "Thanks."

It's been eight months since he ended up in this world, and quite a lot had happened. Not much significant, if he were to judge. Sans didn't really fight any villains or get involved in much so far. Aizawa took Sans back to his house to meet his wife (lovely woman, loves to cook, so safe to say Sans was totally willing to stay for the food) while he was registered as a new person. Sans font, with the quirk known as the Skeleton quirk, which gave him the abilities of a skeleton. Aizawa said it'd be best for Sans to pretend his other magic didn't exist in public, to keep it hidden from villains, which Sans was totally down for.

After Sans was set up, he just learned about this world. About the schools, quirks, expectations, things like that. He wasn't great at it, but Sans had his own little house, a decent understanding of the world, and was officially Aizawa's assistant teacher, so that was pretty cool.

Well, that last part wasn't fully true. He was assistant teacher to the class of 1-A in the school. Class 1-B, the only other class in the hero's program, wouldn't have an assistant teacher. Bad for them, Sans' puns were awesome.

Sans was frankly really glad he was being put in with teenagers instead of children. Sure, Sans was good with kids, but he was a more upfront and real kinda guy. And he was better with dealing with angsty teenagers and their drama. No one knew this, but Paps went through one hell of a rebellion phase. Even drew black lines around his eye sockets and wore leather coats. He always made sure to bring that up to make Papyrus' face go blushing real fast. Good times.

The annoying part about his new life was certainly the stupid fights that broke out on streets. All. The. Time. He was patient, but teleporting in public always caused a panic, forcing him to backtrack and find a less populated spot to shortcut away in. Aizawa once got startled so hard he screamed like a little girl. Sans was never going to let him live that down.

The worst was the separation of good and evil. Sans' karma abilities didn't exactly like that. He was always a middle guy, never picking sides, always staying in the background until he had to step in. Being a hero sounded awful. That's why he was glad just to be some assistant teacher to make sure the kids wouldn't get themselves killed. That meant he could nap all day and enjoy constant fights, like a movie. Sounded pretty nice. No need to say who was good or evil, but just to sit in the background like he always did.

"She also wanted to ask if you were coming to dinner tonight," Aizawa said, bored eyes sweeping across Sans' desk.

Sans and Aizawa had an interesting relationship. Since they were kinda stuck together for three months before Sans got a place to stay, they ended up becoming friends. Aizawa wasn't as lazy as Sans, but he could come close, so they bonded other that, along with their deep care for family. Then there was Aizawa's wife, who ruled. She was awesome! Both she and Aizawa liked Sans' puns, so they would certainly continue to be friends.

"Course. Gotta add some meat to these bones, don't rib me on!" Sans yawned.

"That wasn't even an attempt at a good pun. How tired are you?"
