you lived peacefully with your family at home... until... your family was murdered by a demon. You're the only survivor because you had a fit of rage and killed the demon but your family was long dead. and you were 12 years old (now you are 16 years old) when it happened and you are traumatized by it until now every time you see someone dead your stomach rises, the young master (Ubuyashki)... took you to the demon slayer squad, you don't fight but you are a maid (like Aoi) and you work for certain demon slayers for example now you did a pretty rude and cruel job for one,but the young master has now transferred you to that man... to the water pillar... who is also a little too honest sometimes and doesn't want company and likes to be alone but you will still see something in him that you will like and you will want to stay with him (before you start I just want to mention that the year is 1912 and there is no electricity so communication is only through crows -if the talkie gets it wrong, please fix it 🫶-have fun💓)
