Shota Aizawa was tired.

Honestly, he was always tired. Between teaching work and an active career as an Underground Hero, he barely had the time to nap between classes let alone actually get a full night's sleep. Tonight was supposed to have been one of his increasingly rare nights off, especially with him being put in charge of Midoriya and Nedzu's new Underground Hero classes. He understood the reason for having the classes, and even saw the logic behind having him as the primary teacher and trainer, but he was still human, he needed sleep. So when it was interrupted by Class 1-A causing chaos in their new dorms, he was understandably irate.

"What is going on here-!" he began shouting as he threw the door open, cutting off as he stared out at the disaster area that was the dorm's common room. Glitter. Glitter everywhere as several of his students were huddled between the large tables that had been turned on their sides as a makeshift fort.

"Sensei!" Hagakure shouted, popping up and waving at him, the man surprised by how much detail he could make out of her face due to the mass of glitter that was stuck to her skin, "Make them stop!"

"Who?" he asked slowly, looking around the otherwise empty room, "How did this happen?"

"Midoriya and Aoyama!" Hagakure wailed, "I'm never gonna be invisible again!"

"Aoyama suggested Yaomomo try making those little containers of glitter," Sato called as he tried to comfort the crying girl, thick lines drawn in the glitter on her cheeks marking where her tears were falling, "To practice making a lot of little things at once. She made a lot of them."

"And?" Aizawa growled, stepping carefully over the larger piles of glitter on the carpet, "Why is it everywhere?"

"Aoyama got a hold of them," Sato said, looking up as his teacher reached the edge of their makeshift fort, "He's been chasing Midoriya ever since."

"But why?"

"MAIS YOU MUST SPARKLE, MON AMI!" the butchered French of the familiar blond student echoed from down the hall, a loud hissing being heard a moment later.

"Keep that shit the hell away from me!" Izuku shrieked as he shot into the room, clambering along the ceiling like a spider, Aizawa sighing as he watched the blood claws dig easily into the plaster, and probably the concrete underneath.

Izuku froze as he saw his teacher, visibly swallowing as Aoyama came tearing out of the hallway behind him, hurling a handful of glitter into the air. Izuku let out an otherworldly wail as his body flickered, Aizawa flinching as he watched the long claw marks drag across the ceiling as Midoriya shot over his head.

"AOYAMA! MIDORIYA!" he barked, making both students freeze, "WHAT HE HELL ARE YOU DOING!"

"He must sparkle, Sensei," Aoyama said matter-of-factly, "It is the true form of a Vampire!"

"You're worse than the otakus!" Midoriya hissed from behind Aizawa's head, "At least they didn't try to douse me in that stuff!"

"ENOUGH!" Aizawa barked, making both teens tense, "The two of you are going to be spending the rest of the night cleaning every single spec of glitter out of the dorm! If there is even one piece by sun rise tomorrow, you'll be on bathroom AND kitchen duty for the next month!"

"But why me?" Midoriya whined, "He was the one throwing the stuff!"

"And how are you not covered in it?" Aizawa growled, glaring at the suspiciously clean teen.

"Oh, Ash Form," he replied, "I can just transform part of myself to make the glitter…fall…off…Oh."

"Yes, Midoriya," Aizawa sighed, " "Oh". Now get cleaning. Remember, not a single piece. And that includes on your classmates!"
