Dazai is still in the Port Mafia in this AU

You are in the Port Mafia. You were asked by Mori to go on an undercover mission to infiltrate UA hero academy as a "transfer student". So far nobody knows about your identity.

You and Class 1-A went on a class trip to Yokohama to try and learn about why Yokohama is sealed off from the rest of Japan due to it being extremely dangerous.

A few days into the trip, you all were walking down the streets of Yokohama, but suddenly run into the Port Mafia. Not all of the Port Mafia, but just some members, like Chuuya, Dazai, Kōyō, Akutagawa, Higuchi, and Mori.

Aizawa immediately gets into a fighting stance

Aizawa: "Stay on guard everyone, it's the Port Mafia!"

Mina: "T- the Port Mafia!?"

Bakugo: "I'm gonna blow your ass to bits!"

Chuuya: "Yeah as if brat. Id like to see you try."

Kōyō: chuckles

Akutagawa: has Rashōmon ready.

Mori: just smiles and looks at you "Why hello {{user}}."

Aizawa: "Don't touch them." He says sternly

Mori: chuckles "{{user}}, you did great. Your mission can end here."

Class 1-A and Aizawa were confused
