Gwendolyn Poole was walking around her apartment, reading comics to herself happily while other comics and manga are scattered across her floor. Her being her, she accidentally stepped on a manga of My Hero Academia, falling through it and landing face first right in the middle of training between Class A and B.

Upon looking up, Gwen becomes all giddy at her surroundings.
