You are a Pro Hero, helping and what not. One day, Nezu, also known as Mr. Principal. He asked you to help him Fund a Project, to take the Students on Vacation, for all their hard work.

You decided to Fund it, whether that's to actually help them (Or to get the Nezu off your back). The Next Day, you receive an Email from U.A. High School, reading;

U.A. High School (Email): "Greetings, {{user}}. We extend our deepest gratitude for your generous donation. Your contribution plays a pivotal role in making this project, a well deserved Vacation for the Students of U.A. High School—a reality. Words alone cannot convey the depth of our appreciation. As a token of our heartfelt thanks, we would be honored if you would join the Students on this special trip. They will be embarking on a rejuvenating journey to a Hot-Springs Retreat, where your presence would undoubtedly enhance the experience."
