Iida was sitting in the common room of the dorm, doing his homework, he was waiting for his classmates. Today he took time off from lessons in order to visit his brother in the hospital, he was just learning to drive a wheelchair, and he could use Tenya's help.

When the door opened with a characteristic click, Iida expected to see his tired classmates, who would probably condemn him for skipping classes (not all of them, of course, only certain personalities).

But he definitely did not expect to see Aizawa leading a column of nineteen children 4-6 years old. When everyone entered the room and began to look around and study him, Iida was able to speak.

- Aizawa-sensei what... What happened?!

Tenya jumped up from his seat on the sofa. He studied the children carefully. They were all eerily similar to his classmates.

Here is a boy with a shock of curly green hair, and next to him is a girl with big chocolate gases and pink cheeks. Behind them stood a boy with spiky blond hair and a boy with black hair and a scar over his right eye. Next is a very quiet boy with multicolored hair and a burn on his face, and a very excited girl with dark hair gathered in a ponytail. The three most active ran into the common room and immediately sat down on the sofa, they were a girl with pink skin and hair and two fancy horns, a boy with bright yellow hair and a black spot on his bangs and a black-haired boy with modified elbows and a triangular smile.

Iida approached the teacher, continuing to look at the children, the quietest of whom began to scatter in the corners. The boy with the raven's head went to the TV (which was turned on by the restless trio), the boy with the tail carefully walked into the kitchen, followed by a tall boy with plump lips and a prickly hairstyle. A boy with a mask and several extra limbs tried to drive the grape boy away from the blue-haired girl and the frog girl. Iida noticed an invisible girl and a sparkling boy near the elevator, in the door of which there were their reflections.

Only the quietest stone boy remained. Iida found him behind Aizawa's back.

- What happened to them, Aizawa-sensei?

- We are finding out, presumably this is the action of someone quirks. I'll ask you to keep an eye on the kids while we figure out who did it. - Aizawa said.

- I'm counting on you, Iida. - Aizawa went to the door.

- I won't let you down!

Iida shouted, cutting the air with his hand. Shota mumbled something and closed the door behind him.

A few minutes later, Iida realized that he was ALONE with NINETEEN children for an unknown amount of time.

- It won't be difficult, these are my classmates, right?

There was a crash of falling dishes from the kitchen, and something exploded in the common room, after which someone began to cry.

- Right...?
