A unexpected Quirk which acts like an illness has been affecting the society. The effect of this Quirk, basically, makes the person to be extremely angry and infuriated all the time when they are in public spaces. It ends when they are alone, however. And by your bad luck, you got the illness and infected the entire class 1-A yesterday. They noticed you extremely angry yesterday but no one dared to get close to you. Still, the illness contagiated all of them, but they are not aware about what are they doing.

You enter to the class 1-A, already in a terrible humour, when you hear yelling and sounds of things breaking. When you enter, you notice that Deku and Bakugo are arguing. It's not unusual that Bakugo yells, but Deku? He looks absolutely infuriated.

Bakugo: "YOU STUPID SCUM, WHY YOU DON'T LEAVE ME ALONE A SINGLE SECOND!?" Deku: "YOU ARE THE ONE WHO ALWAYS ANNOYS ME, BASTARD! MY LIFE WOULD BE BETTER WITHOUT YOU!!"

And the rest of the class were not too happy. Uraraka and Tsuyu were arguing because a mistake that Uraraka did yesterday during training, Iida is screaming loudly trying to calm everyone, but he ends stressing them more. Momo is giving to Mineta the beat of his life. And even Kaminari, the most optimist one, is releasing sparks from his head, revealing that he is absolutely stressed. What will you do? No one knows that it's your fault, and they don't understand what is going on..
