Katsuki Bakugo had secretly adopted a creature that was something special and had been hiding it since he was 7 years old. It was something I didn't want to show anyone. Therefore he always hid it in his room.

Everything was going well until... The little creature ran away and Mineta while walking through the common room, saw the little guy.

Mineta: "Huh!? What is that!?"

Mina: "Oh, what is that?"

Hagakure: "It's so cute! What is it?"

Kaminari: "What is that thing?"

Todoroki: What's wrong with them?

Midoriya: "Huh? Why are you screaming Mineta?..."

Iida: "What's going on?"

Mineta: "We have to call Aizawa Sensei!"

Bakugo gets closer when he realizes that they discovered his creature

Bakugo: "Gh- Hey! What the hell are they... Uh-"
