Sans ducked beneath another spear aimed for his head. Undyne was a good teacher, but she was brutal. He could keep up with her only because he knew her. He could use the lesser science of psychology to predict her attack pattern. When she was tagged out with Aizawa, he started struggling.

He didn't pay attention to his teacher during the USJ attack for obvious reasons so Sans didn't know his attack pattern. The internet helped some, but Eraserhead was still an Underground Hero and there were few videos of him and the ones Sans did find were dark and hard to watch.

Sans was able to duck and weave through the attacking scarf, but when Aizawa realized that, he used his scarf as a distraction and started up close combat. Sans, to his credit, blocked most of the attacks with the pole part of his weapon, but it was like he was receiving shockwave damage through his hands from holding onto the staff.

Tremors in his hands would echo throughout his body giving him full body shakes for a few seconds. Asriel and Kota cheered him on from the sidelines. As it turned out, Asriel and Kota went to the same school and were best friends. Sans jumped on a blaster to evade Aizawa's scarf.

Sans - "Yo, you want to take a break? I'm tired and hungry."

Shota - "Sure. Asriel and I had plans to surprise Hizashi at the school. We'll come back later. Az, ready to go?"

Asriel - "Sure thing! See ya later Kota!"

Asriel ran and followed Aizawa to his car. Leaving Sans and Undyne to their devices.

Undyne - "You're getting better Sans. I'm headed home to check in on Daichi and Alphys. When I get back I'll show you better ways to block with your staff. What you were doing would only rattle your bones and muscle and, if this were a real fight, you'd drop your weapon. I'll talk to Power Loader about shock suppression gloves."

Undyne gave him a rough, well meant noogie before jogging after Aizawa and Asriel. Sans put his gear away and decided to take a walk around the grounds. See how everyone else was taking their training. His bro was keeping his Quirk activated while Ojiro used martial arts with his tail against him.

Sans - "Great job guys. Keep it up Eiji! Give it everything you got Ojiro!"

Sans cheered them both on then moved on to the next group. Sato and Yao-Momo were eating lots of sweets. Sato was eating and weight training and Yao-Momo was eating and making little Russian nesting dolls.

Sans - "You guys are doing great, but be careful to not overeat. You don't want to yak all over the place."

Sans rubbed both their backs with sympathy. Once, at Grillby's when he was younger, he got into the pantry and ate so many raw potatoes that he threw up in his bedroom later in the day.Not fun.

He was walking next to a little cliff side where Sero was screaming and shooting tape over the edge.

Sans - "Try to push through it Sero!"

It hurt Sans to hear a member of the squad in pain, but they were doing it to ultimately improve their Quirks, mostly of their own accord so he couldn't help them the way he wanted to. He paid a visit to the rock face where Mina, Jiro, and Tokoyami's cave was. They were hard at work and too busy to talk so Sans offered a couple words of encouragement before seeking the answer to the fluctuating temperature and eardrum-shattering explosions.

Todoroki was inside an oil drum. Each time he smacked the drum waves of ice and fire shot out. He was out of breath and sweaty, but he was working hard and it was paying off. Close by, his Katsuki was thrusting his hands into an oil drum that had steam radiating from it. He would keep his hands in the boiling water for a few seconds before taking them out and unleashing a massive explosion toward the sky. A second or two after the explosion, the chaotic good blonde would jam his hands back into the water.

Sans - "That's my Katsuki at work! You're doing great G.Z! You too Peppermint Bark!"

Sans waved at them both, spending a few more seconds shamelessly ogling his boyfriend before setting off again. Todoroki looked surprised but had a light blush and soft grin. He and Sans don't typically interact much, especially since Valentine's Day, but the little environment made him feel...good. Good about himself and his quirk.

Katsuki was red faced both for his raging affection for Sans and in general rage about Todoroki's gooey puppy eyes toward Sans's retreating figure. Katuski finished that day's training earlier than expected. He wandered around until he found Sans struggling with weight training with Tiger. She was Sans's spotter and poor, weak Sans could barely lift fifty pounds without struggling and shaking.

Tiger - "Bakugo. Stay here and spot Sans for me. I'm going to retrieve items for dinner."

Katsuki - "Sure thing. Beat it. What's up Richter?"

Sans - "Tiger found me wandering and forced me to start lifting. The M.E repoart is gonna have phys.ed as the cause of my demise. I leave all my earthly possessions to Mayo."

Katsuki - "Drama queen."

Sans - "Damn straight. Soon as you put a ring on it, you'll be my drama king."

Sans was trying to make a joke, but Katsuki's face was bright red and he spaced off, his hands losing their grip on the dumbbell.

Sans - "Uh, G.Z, I'm slipping. Kats? Katsuki!"

Katsuki - "Shit!"

Katsuki quickly and easily lifted the bar away from Sans's neck and placed it on the rack. After a few minutes they both took turns using the dumbbells. It wasn't long until they called it a day and Katsuki carried his koala-esk boyfriend to the area where the class had to make dinner. Katsuki was pissed, Sans was irritated.

They still got to work and moved in harmony preparing a hearty chili and cornbread. Sans wanted western food so he took the lead in preparing everything and dishing out orders. Katsuki was his right hand and assisted in showing people what to do. There were three teams; meat, vegetables, cornbread. Self explanatory really.

The food was done in no time and everyone tucked into the food with renewed vigor. The hotspring was once again the place to go after dinner. After washing his hair and cleaning himself off, the girls whisked him away to the female's side. Sans didn't care what side he went to, but something felt wrong about being on the girl's side of the wall.

He shrugged it off and enjoyed the hot water. He could sense Kota's soul at the top of the wall. Probably keeping an eye out for pervs, though, Sans didn't believe there would be any issues.

Asui - "Sans, I was wondering for a while now. What's your sexuality?"

Uraraka - "Tsuyu!"

Asui - "What? You all were curious and wouldn't stop talking about it."

Sans - "Heh, I guess since Katsuki is my first boyfriend and he's a dude and since I feel no attraction to you girls, gay? Asexual, hundo percent."

Mina - "Called it! Pay up bitches!"

Sans - "Y'all made bets?"

Hagakure - "Yeah, we sort've have a betting pool going on the class."

Yaoyorozu - "It's why we felt comfortable enough to invite you here."

Jiro - "We all understand consent and some if not most of us are lesbians."

Uraraka - "We should get the guys and go to the next Pride Parade!"

Jiro - "That'd be awesome! I could do everyone's makeup!"

Sans kept quiet since he didn't even know what a Pride Parade was, but the girls all looked incredibly excited and happy, so he couldn't ruin their fun. It wasn't long before the girls dragged him to their room for facials and nails. Sans was sporting a cute koala themed headband, a mint green face mask and ice blue nails. 

He may no longer be a pale looking human, but blue and every shade of blue was still his favorite color. And gold. Mina was in the process of painting cute golden flowers on his nails to go with the blue. Sans was happy and sleepy and wave loving the skincare routine Momo was teaching him. He went to sleep with noise canceling headphones and a dopey grin on his face.
