"Sans, it's time to- oh. You're already up?"

"Yeah. Morning bro."

"Are you okay? Your eye's acting up."

Sans looked up from his book, into the mirror in Eijirou's hand. Sure enough his right eyelight was gone and his right was blown up, blue, and a tiny red light was in the middle. With a groan, Sans willed his magic to calm down, returning his eyelights to normal.

"Just a bad dream bro, it really, rattled my bones."

Seeing the lack of laughter in Eijirou, Sans sighed out a quiet hum.

"Don't worry Eiji. It was just a bad dream. Nothing too serious. Come on, we don't need to be late to school. We can grab some grub there."

Sans latched onto Eijirou's arm and took a shortcut to the UA cafeteria. He and Eijirou had a relaxed breakfast of rice porridge, a fried egg, and bacon. Sans started dozing off immediately after eating. Eijirou sighed as he lugged Sans to the classroom under his arm. Being the first ones there, even before Aizawa, Eijirou let Sans sleep as he left to fill up his water bottle.

As soon as Eijirou left, Bakugo arrived. He saw the sleeping Sans, growing annoyed for no particular reason.

"Oi, Skeleton, wake the hell hell up."

Bakugo shook Sans's shoulder, none too gently. Sans, now startled out of his sleep, threw a sharp left hook. He was roused out of his sleepy state by a sickening crunch. Bakugo had thick blood streaming down his face with a shocked look on his face.

"Hey, Bakugo, you're here earl - oh shit, what happened?!"

Sans looked at his still curled fist with a bit of blood on his knuckles. Wiping it off on his pants, he turned to Eijirou.

"Hey Eiji, hold him still for a moment. I think I accidently broke his nose."

"Accidently?!"

Bakugo was now out of his shocked state as Eijirou held him, preventing him from hurting Sans. Carefully touching both sides of Bakugo's broken nose, a soft green light shone through the pale fingertips. Bakugo's nose was fixed and no longer bleeding.

"There you go. Eiji, that took...more energy than...I thought. Good night."

Sans fell backwards, quickly caught by Bakugo.

"Shitty hair?"

"He can heal very minor injuries, but it takes a crap ton of his energy. Here, a clean shirt that doesn't look like you committed a murder. While you're out, bring back some food for my bro? He needs more energy."

"Tch."

Snatching the clean shirt, Bakugo stormed out, running into the rest of his "Baku-Squad", or as he called it, his squad of dumbasses.

"Kacchan, what happened to you?"

"Fucking Skeleton broke my nose when I woke his ass up."

"It doesn't look broken?"

"That fucker healed it Raccoon Eyes. Home Depot, go to my locker and get my bento."

"Why me?"

"Because I said so."

Sero grumpily made his way down the hall. Sans eventually woke up, but was extremely drained. Healing magic, while somewhat common among Monsters, was still extremely difficult to use and he wasn't good at it at all. So he didn't use it all that often.

"Eiji, I'm sorry. I didn't mean to break his face."

"Bro, it's fine. You healed him right after so there was no long term damage. You okay though? You never get that violent when people wake you up."

"I was having the same nightmare as last night."

"That bad? I'll ask Ma if there's something she can do to help you."

"Thanks Eiji, I'll try not to lash out like that again. I think your friends are here bro. You go, I'm chill right now."

"If you're sure."

Eijirou gave Sans's snowy hair a good shuffle before going to his friends. Sans stayed awake, with his head down, fighting the new, and unpleasant phenomena, a headache. He never got one when he was still all bones, but now his fleshy body got one after every night of no sleep or nightmares or if he overused his magic.

Sans felt something hit the top of his head. It didn't hurt, it felt more like someone trying to get his attention than someone being angry with him. Looking up, Bakugo stood there with a bento of grilled fish, two onigiri, fruit, a lightly salted rolled omelet, and a thermos in his other hand.

Silently, he placed the bento and thermos on his desk and stomped back to his seat. Taking a sip from the thermos, Sans guessed it was coffee. Sans didn't like coffee because it was typically a bitter drink and he hated bitter foods, but the coffee had the perfect amount of bitter and sweet. The food was good too, full of bold flavors with the onigiri hiding a small amount of spicy mayo in the middle. He didn't normally like spicy food, but the flavor was great and the spice helped him wake up a bit.

"Thanks Bakugo. This is really good."

"Don't look too much into it. It just means we're even, Bonehead."

"Oh, is my nickname getting an upgrade?"

"Shut the fuck up!"

Sans laughed as he savored another sip of the divine bean juice.

"Got to hand it to you Boom Boom Boy, I hate coffee, but this is delicious."

"What'd you call me?!"

"Chill out Angry Pomeranian, it's just a joke."

"I'm not a fucking dog!"

"Yeah I know, you're more of a Cat-suki."

Sans busted into peels of laughter with the Baku-Squad as Bakugo yelled in indignation. After he calmed down the rest of the class and Aizawa shuffled in. Aizawa still didn't trust Sans. After the Combat Training with All Might, he trusted the too-thin boy even less. Nezu's USJ Training is today, so he was interested to see Sans's quirk in its entirety.

"Shut up and let's go. We're going to a different location for your Hero training today."

Sans was carried out of Eijirou's back, the red haired boy still worried about Sans.

"I'm fine Eiji."

"I'm not taking any chances. You fell asleep standing and almost cracked your head open on the sidewalk and I don't want that to happen again."

"Okay, that was one time, and I'm not tired anymore. I drank coffee."

"Okay."

Sans now stood next to Eijirou, walking next to him to the buses outside. Eijirou ended up sitting with Kaminari, and Sans with Todoroki.

"Hey Peppermint Boy."

"I'm not a peppermint."

"Are you sure? I could hold up a piece of peppermint candy right now and wouldn't be able to tell the difference."

Sans chuckled (ahem giggled) at his own joke, with lightly dusted blue cheeks. Sans spent the majority of the bus ride blissfully unconscious, much to Eijirou's exasperation. Bakugo took it upon himself to hoist the unconscious Sans on his own back, with the excuse of weight training.

The real reason was to judge Sans's weight. He could tell immediately that he had no muscle mass, anywhere on his body; the complete opposite of Eijirou's body type/weight. Bakugo pulled Kirishima off to the side when they got off the bus.

"Shitty hair, is he eating properly?"

"What?"

"He has no muscle mass or any kind of fat on his body."

"That's because of his quirk. He can't gain weight like we can. He can down three jumbo hotpots by himself and not gain more than two pounds. My moms were worried at first, but resolved to making him more fatty foods."

"Kirishima. A word. Bakugo, go join the others with Sans."

Aizawa appeared from nowhere with a narrowed look in his eyes. Bakugo clicked his tongue and did as told.

"When did you meet Sans?"

"Um...my mother told me not to answer questions about Sans without him present. That it's an invasion of his privacy."

"I'm just asking when you met. I won't pressure you to tell me about his past."

"Okay, I guess that's fine. We met three years ago. I don't think I can answer any more questions."

"His quirk. Explain it to me."

"That's easy! It's so cool, it's called Shortcut! He can teleport anywhere he's been before if he has the destination pictured clearly in his mind. Really useful when we're almost late to school."

"Alright, thank you. Go join your classmates."

"Okay sir!"

Eijirou ran off to get Sans. Aizawa lifted his phone to his ear.

"Did you get all that Tsukauchi?"

"Yeah. The only information we have on Gaster W. Sans is his middle school records from two years ago to today. Kirishima was definitely hiding something, so keep an eye on him. I don't think he's a villain, but I would like to hear this young man, Gaster speak. Next time you're alone with him, get me on call and ask him questions. I might be able to get a read on him. I have to get back to work. Good luck Shota."

"Thanks. Bye."

Aizawa hung up and stalked back to his class.

"What are you hiding, Gaster W. Sans."
