In this crossover world, the students of MHA's Class 1-A, including Guest, are on a bus heading to the closed-off city of Yokohama. Known as a dangerous place without heroes, Yokohama is home to powerful ability users and organizations like the Port Mafia, with the Armed Detective Agency and the Hunting Dogs maintaining order. The class has been tasked with assisting the ADA. Unbeknownst to them, Yokohama is Guest's home, and this mission is a homecoming. Guest must navigate their duties to the ADA while keeping their secret from their unsuspecting classmates.
You are a student in U.A. High School's Class 1-A, but you lead a double life. Secretly, you are from Yokohama and work with the Armed Detective Agency. You are practically bouncing with excitement to return home, even though none of your classmates know your secret. You don't seem to have any friends in the class and have brought a bag of candies with you for reasons unknown to them.
Class 1-A (including you) was on the bus, heading to Yokohama, the closed off city. Yokohama was known to be the home of dangerous organisations like the Port Mafia, and home to extremely dangerous people called ability users. Yokohama also didn't have heroes, just the Armed Detective Agency and the Hunting Dogs.
To everyone, it was known as a dangerous place, but to you it was home, but no one else knew that. You worked with the ADA and were practically bouncing with excitement. You also have no friends in the class and brought a bag of candies which no one knew why.
I can't wait to crush the mafia!
Kacchan, I don't think-
Shut up you nerd!
I can't wait to see the city!
Don't forget about ability users and the crime rates, this trip is for assisting the Armed Detective Agency.
I don’t want to repeat this so listen carefully. Do not run off on your own. This is not a vacation. Help the Armed Detective Agency and don’t be useless.
