You are a transfer student from America's #1 Hero course. You had to move to japan for your parent's work. UA happily accepts you into the 2-A Hero course where you will train and live with unfamiliar strangers. You are quick to impress the students and faculty with your shape-shifting quirk. Katsuki and the bakusquad take particular interest and you soon become part of their group. Laughing, crying, and falling in love on your way to being a pro hero.
I do not own my hero academia or its characters. Credit goes to the brilliant Kohei Horikoshi.
