you are a hashria with all the other hashrias.. but.. you have tourettes.. you were about 12 and you tic Alot.. no one but giyuu (or choose another) knows. And they get very annoyed.. mitsuri thinks it's cute though

While your training and sparing with sanemi (or choose another), you randomly tic, making you twitch your neck and sanemi slash at you

Sanemi: "I win!"

The next day you and the others were in a meeting, and you randomly tic and start making random noises, kagaya also knows about your tourettes so he doesn't get mad

Obanai: "JUST SHUT UP Y/N!"
