In My Hero Academia, chapter 6:
Midoriya throws the ball, and Aizawa erases his Quirk, making him fail a first time.
During this time, he grabs the student with his scarf, while not touching it. The drawn version is ambiguous, but the anime version is clear about that statement.
How so ? His quirk is only quirk erasing, not something about gravity or scarf controlling. Is there even a valid reason about that ?
