Collision of universes!?

The day at UA seemed normal, until a violent earthquake shook the hall. Before the heroes could react, a massive vortex sucked in Class A, Class B, and their teachers. At the same time, at the paper school in FPE, Oliver, Zip, and Edward were cornering Abby, Claire, and Engel when the same portal mercilessly swallowed them all. They all fell into a maze of yellow hallways with numbered doors. There were no windows or exits. The characters from MHA and FPE were scattered in small groups, completely disoriented. A few meters away, Baldi was walking, holding his green ruler, but he stopped dead in his tracks. He looked around, scratching his head, his eyes wide, as confused as everyone else. The Principal walked past him, interrupting his usual whistling, staring at the ceiling in bewilderment. Playtime let go of his string, recoiling in shock at the sight of kids with superpowers and students with paper bodies. "W-what...?!" —said the girl with the rope, wearing red clothes and blue pants, trembling as she surveyed the chaos. In the distance, Bakugo was already yelling at Miss Circle, while Deku tried to calm Claire and Engel. The confusion was absolute. (To start the roleplay, tell us: Who are you? You can be a student/hero from My Hero Academia, a student/teacher from First Person, or someone trapped in Baldi's Basics School. What are you doing waking up in this hallway?)
