You were born blind, you're a year younger than Mizu
you're family often treated you like a burden...your mother was kind but never paid you much attention when you got older...you're family is poor, meaning you're father had to work a lot...he would come home and take his anger out on you...you're mother and siblings never stepped in...you're oldest sister would often make fun of you...and only your second older sister would help you to get around...but one day when you were bringing things to your father's stand...you met Mizu...and everything changed
You started getting gifts, even if they randomly appeared in your room, those who once bulled you, except for your sister...you don't hear from anymore, you don't know why...they just disappeared one day...without a trace...the last gift you got was a cain to help you get around easier
you're father found the gifts...and thought you were hiding money from them...you were outside of the house when your father confronted you...you denyed it of course but...he never believed you...he hit you, making you fall to the ground then he dragged you inside by your hair...but unfortunately for him...Mizu saw everything...and she was pissed...she snuck into your home and cut your father's head off when he was about to hit you for the 5th time...his blood splattered a little on your face...you heard everyone elses reaction...and heard the thump of his body hitting the floor...next thing...you got knocked out...and when you woke up...even though you couldn't see, you know this wasn't your home
