A peculiar Adveture - UnderTale x BNHA Crossover

Chapter 3 - Red

Sans' POV

I was sitting in the back of the class, not paying attention to whatever Mic was teaching. It had been a couple of days since I met everyone. They all introduced themselves to me and we all hung out to get to know each other. Aizawa had also shown me where my room was in the dorms, but I've been to lazy to decorate it.

I opened my eyes only to be met with groans and whinning.

"But Present Miiiiiiicc-" Denki whined

"No buts, Kaminari," Iida told him, "This will be good for our GPA,"

"I don't want to give you guys a surprise test either, but it was All Might's idea," Mic stated, passing out papers.

"Are we not All Might's favorite class anymore?!" Mina yelled.

"He said it would be good, since everyone has been so laid back lately. He said it was like a surprise villain attack," Mic walked  back to his desk.

"But this is English, not hero training," Sero and Kirishima whined. I rolled my eyes and laid my head back down.

"You have to take it too, Sans," my head shot up immediately.

Deku's POV

"What- but why??" Sans cried.

"Because we need to know what level of knowledge you have," Mic informed.

"But I already finished school," Sans whined, putting his head in his arms.

"Wait, really? Wait, actually, how old are you? I just realized we never asked," I asked.

"I'm 23," Sans looked up with a deadpan look (google said he was 20-30 so I chose how old I wanted to make him). Mic shrieked.

"WHAAT!? I YOU DIDN'T SAY ANYTHING?!?" he yelled.

"I didn't think it was important, plus, you never asked," all of a sudden, the classroom door opened to reveal a timid looking All Might (in his buff form) holding a skeleton by the hood, his arm extended. The skeleton looked up at the buff man angrily, throwing punches and scratching wildly, which couldn't reach All Might.

"Sorry to interrupt your guy's tests.. but I found this," All Might walked to the front of the classroom. "Sans, do you happen to know who this is? He's a skeleton like you, so I thought maybe he was your sibling or something," he looked unsure.

"Um, first of all, just because he looks like me, doesn't mean I know him," Sans stood up, walking over to All Might. "and second, yeah, I know him. But he's not my sibling," the angry skeleton stopped moving, and looked at Sans.

"Classy? What are you doing here with these idiotic looking people?" the mean looking skeleton asked as he hung from All Might's arm.

"I don't know, I guess I got tired and thought I needed a vacation away from home, so I came here," Sans stated with a straight face.

"Wait, actually?" The mean one asked.

"Of course not you bonehead. If I ever needed a vacation, I would visit you," Sans lightly hit the other one's skull.

"All right, so that's settled," All Might dropped the skeleton and the skeleton landed on his stomach. He hastily got up and wiped himself off before glaring at poor All Might. "Okay kids, have fun on your surprise test," and with that, he ran out. There were groans throughout the classroom.

Sans' POV

"So, where'd you wake up at? I woke up in a dumpster behind the school," I asked Red.

"Oh, I woke up to falling on top of the giant man. Their were other adults in the room, I think it was a staff room," Red scratched his head. "What are we doing here anyway?"

"I'm not sure, I'm told that someone's quirk malfunction and brought us, but that might not be the case," I thought for a moment, "How's everyone doing at home?" I saw Red smile.

"Oh you know, just trying to kill each other, the bad Sans' actually almost succeeded in destroying an AU. That was before they were almost beat to death," I chuckled as Red shivered, "Remind me to never mess with the Star Sans' spa day,"

"Damn, all that happened all in the past couple days I've been gone?" I asked, "I would've loved to see their asses getting beat," Red laughed.

"Are you guys done yet? We have a test," Mic asked.

"Yeah, Sorry. Also, do I still need to take it?" I asked hoping I didn't have to.

"I suppose not, but you still have to hang out here. You can talk to your buddy in the back,"

"Alright, cool," I grabbed Red's arm and walked to the back.
