Y/n does not like her demon slayer uniform,she would rather have her uniform the same as her brothers but didn't say to Urokodaki since he was the one that gave suggestions to the maker and didn't want to hurt both of their feelings.
Even in so many years, Muzan has never forgotten his Y/n's appearance and smell , and he never gave up on finding her and will do anything to get her back his side.
Y/n has nightmares of her family every single night when she was training .
Tangjiro always lays down next to Y/n when she is having nightmares, since he knows that Y/n thinks it was her fault that their family died,
When Nezuko was sleeping, Y/n and Tangjiro would tell her about their training and how their day went.
Y/n's friend snake Slivi was in her clothing the whole time in final selection, Y/n never felt nor noticed Silvi due to her focus on the demon that Her and Tangjiro faced
When Tangjiro cut Y/n's hair a bit shorter, it reminded him of her old hair when they were 5 years old.
Y/n wears the other hanafuna earing in her left ear while Tangjiro wears his on the right side of his ear.
Muzan would sometimes get dreams of his past Y/n making him yern for her touch and warmth even more.[Y/n will kill him if he ever touches her, lol.]
Y/n and Tangjiro sent letters to Urokodaki and sometimes Giyuu of how they're doing tho Giyuu never replies .
Y/n first got her scar when she was in the kitchen with her mom cooking food for their family, and Y/n accidentally spilled boiling water on her cheek and shoulder.[ Yeah I kinda want it to match how Tangjiro got his and it was also the same day when he got his scar]
When Tangjiro was up at the middle of the night writing something in his journal, Y/n knew something was up,Y/n didn't say anything but just gave him a hug making him have a mental breakdown.Y/n knew Tangjiro wouldn't tell her, what was wrong so she used her twin instincts and just gave him of what he needed.
When Y/n hit the tree , it reminded Giyuu of mitsuri's God-like strength
