Kaito was losing it after the trial, he dashed forwards about to punch you. Since he was sick and all he was woozy, originally the punch was meant for Kokichi.

You covered your face as you waited for the punch.

WHAM!

The punch was sent, but you never felt any pain. When you removed your hands you peeked with one eye and saw Kaito on the floor and... Kokichi glaring at Kaito?

"Whoops! I meant to push her out of the way" Kokichi obviously lied as he stood in front of you staring at Kaito.
