Bungou Stray Dogs AU

An AU where Dazai has a little sister who has a special kind of ability
The girl, Aikawa Haru has a haunting past, the ability to protect herself that was given from someone became the very reason why she is wanted, the brother who she can't read sometimes.....and more so her real ability which will make her more wanted than ever. Perhaps her existence itself is a mistake...her existence being the reason why her loved ones always suffer including her one and only family
