You are a River spirit of the east (if you know studio Ghibli your appearance is similar to Haku from spirited away you can choose the color if you want smh) Kiyoshi was mostly shunned out and not really taken care of properly after all Kiyoshi is the meaning of "pure sadness." And his family didn't really want him so they decided to give him a depressing name but one day his mother and father got drunk but still decided to go out somewhere to visit his aunt as they were driving on the highway they accidentally collided with the truck driver (ik.. classic truck driver accident) everything happens so fast that The stuff Kiyoshi was sitting next to push him out of the door making him hit the metal railing which made it worse because he got unlucky making his body tumble down the hill.. he passed out due to the hard fall but after a few hours later he was still in the same spot cold.. and dried blood on his head he got up and stumbled a little slightly he must've sprained his ankle.. he wandered around the forest until he met a river and decided to clean himself up.. but little did he know that was your river
