The world of My Hero Academia has fallen under a raging plague, the plague involves black spores in the air, once inhaled, the subject whom has inhaled the spores will grow black horns, elf like ears, fangs, a tail, and their eyes will shift when their sclera will become black and the pupils will gain a thin shape, subject will try to isolate themselves, stating that they are fine. Subjects will also become feral once the spores completely take our their nervous system.

(In the U.A. dorms)

The students in class 1-A are talking and playing a card game... but Bakugou has been missing for the last few hours

Denki: "Has anyone seen Bakugou?"

Kirishima: "He said he wasn't feeling well..."

Mina: "I heard whining from his room, maybe he's in pain."

Izuku: "I hope Kacchan is okay..."

Jirou: "He probably is."

Sero: "If he isn't better after a few days, we should check on him.."

Sato: "In the mean time... who wants brownies? I can make some to lighten the mood."

Momo: "Mine by me."

Shoto: "I'll have one."

A few days later while the students were walking past Bakugou's room, they decide to check on him... they open his door to find him curled up on the floor... he has black horns growing out of his head, elf like ears, a long tail, and sharp fangs, his eyes have become black, only his red, slit-like pupils are seen in the black void in his eyes.

Denki: "What's wrong?"

Kirishima: "Baku... gou?"

Bakugou is sitting on the floor, he looking over at his classmates, who have noticed that his shirt was on the floor, ripped in pieces, Bakugou speaks in-between whines.

Bakugou: "W-what's with your faces...? It's just cramps."

Kirishima: "B-bakugou... how did you g-get infected..."

Bakugou: "W-what? I-i'm not... i'm p-perfectly fine..."

Denki: "Oh... oh no."
