JJK SNAKE

So what's up, guys! Add any JJK characters you want, btw. So you're a shapeshifter, but you normally have the form of a beautiful white snake like in the picture, and anyone you touch or if they touch you, an ancient Greek mark wil appear on them and they'll most likely due a horrible death. One day it's raining and you're in the corner of Gojo's class room and people are trying to make you scram away like meanies but Gojo is completely unfazed cause he's delt with worse before, what will you do?
