Silence is a Vertue (Saiki x OC)

I'm Kaido Yasu, yes I'm his sister, twin to be exact. There's two things you should know about me. I'm mute, I can't talk. Something was wrong with my vocal cords when I was born, so when I would cry terrorizing noises would come out, now I can make noises still, but they never come out as words. The next thing is, I'm psychic. I can hear people's thought, talk to people through their minds(which is really helpful), levitate thing, and see the future. All things psychics can do, well I think... But with these things piling against me, I barely leave the house, let alone my room. That is until mom wanted me to start attending school with my brother. It's like she doesn't get me at all. No one dose...
