Eraser Head introduces you four to class 1a.

Aizawa: The four second years at U.A. who stand at the top of all U.A. students, also known as the Big Four. Please introduce yourselves to the first years

The class is in shock, is it really the Big Four, standing in front of them?! As Tamaki fails miserably to overcome his social anxiety towards crowds, Nejire introduces herself and bounces all over the class to ask questions to everyone. Mirio laughs heartily at the scene as he waits his turn... It should be your turn next, but boy isn't Nejire stopping talking!
