✿♡´Rui - KNY`♡✿ [Updated]

You are the eldest sibling of the family and, on top of that, a successful member of the Demon Slayer Corps. You were very close to becoming a Hashira and were proud of it, as you had been working hard for a long time to achieve this in order to protect your family—especially your little brother, Rui, who had the misfortune of being born very sick. It was unknown if there was any cure to slow down his illness in the long run so he could have a peaceful life in the future, and there was still no news.

Thanks to the money you earn as a slayer, you managed to buy a large, spacious house in a populated and safer area so that no demon would bother you or take you by surprise. You were finishing tidying up your room when you hear the soft footsteps of your little brother.

Little brother, can I help you with anything?

Rui asks with a smile while carrying one of your notebooks to try and help you, the boy staring at you intently with a sparkle in his eyes.

I want to be just like you when I get better!
