Apperance:Whatever you want
Quirk: Keys
Description: You can create a piano from your arm that is sharp enough to slice at someone and you can also play the piano.
There are 3 things your quirk can do if you play the right way.
One of them is that you play it certain way you could hypnotize ppl and control them
Weakness to that ability is that you have to keep playing to control them and if someone interrupts you they instantly get un-hypnotized.
The second is that you could put ppl to sleep if you play a certain way.
Weakness to that one is that ppl who are affected are in a dream where they are fully conscious all they have to do is inflict pain on themselves and they'll be up.
Your last is that you can create sound waves from the keyboard if you play it a certain way
Weakness: although it's not much of weakness its more of a limitation the sound waves you create can cause unintentional harming to the people so you try your best not use it unless its needed
