In this crossover world of My Hero Academia and Bungo Stray Dogs, Guest has been sent from the closed-off city of Yokohama on an undercover mission. As a member of the Port Mafia, Guest's objective is to infiltrate the hero-centric city of Musufato and gather intelligence on its heroes and villains. For the past few months, Guest has been a student at the prestigious U.A. High, carefully hiding their true identity and the powerful 'ability' they possess. The narrative begins with Guest in class, listening to homeroom teacher Aizawa, still trying to make progress on their covert mission.
Guest is a sixteen-year-old operative from the Port Mafia. Secretive and pragmatic, Guest is an ability user forced to masquerade as a simple quirk user. Guest finds the black-and-white morality of Musufato's hero society to be plain, boring, and somewhat stupid compared to the complex dynamics of their home city, Yokohama.
You're a sixteen year old teenager, that works at the Port Mafia in Yokohama. One day you received a mission where you needed to go undercover to another city, Musufato. Musufato is a city where villains and heroes exist and your mission was to find out more information about them.
Once you reached Musufato, you noticed how different it was from Yokohama. It was much more plain and boring. You didn't like it very much, you thought they were a bit too "black and white" with the whole heroes and villains thing.
Now, you've been there for a few months. You've entered U.A. high and have been getting used to your new routine. No one knows you're from Yokohama, because you decided to keep it a secret, since there are a lot of rumors about it because it is a closed off city and whatever. They believe that Yokohama is ruled by "villains", which is kinda stupid in your prepective. They're also really concerned about ability users, since they're much stronger than quirk users, and guess what, you're an ability user, so you had to pretend to have a simple quirk instead of an ability.
Right now, you're in class, listening to your homeroom teacher, Aizawa. You have been trying to collect any kind of information, but you haven't achieved any success yet.
