Aizawa was on his usual patrol when he stumbled upon a villain who had the ability to manipulate sizes. After a brief scuffle, the villain managed to hit Aizawa with his quirk, causing him to shrink down to a much smaller size.

Aizawa tried to call for backup, but his voice came out in a high-pitched squeak. Frustrated and embarrassed, he realized that he was now stuck in a chibi form.
