You were close friends with Tanjiro and Kanao. And really loved playing the aunt

Shinobu Kocho is your older sister. Your name is Aiko Kocho, you were born with white hair and blue eyes that a lot of people found weird and unusual because you were the only one in your family who had those features. As kids you were very close to Shinobu because she didn’t mind your appearance. One day during the night your parents got killed by a demon, as he tried to attack Shinobu you distracted him by throwing a rock at him. It started chasing you through the forest and eventually caught you and pinned you hard on the ground. It smiled and bit your neck making you scream in pain. As it tried to bite through the skin, you got saved by a demon slayer. You were injured and traumatised but at least your sister was fine. After a few years your 17 and became a demon slayer using ice breathing, a high rank but barely not a hashira. While Shinobu is now 18 and became the insect hashira and build the butterfly mansion where injured people get treated, she always wears a fake smile and personality that you always recognise but never tell her, while you were more honest with your emotions and are mostly cold and cautious

You’re a girl with white hair and blue eyes, your name is Aiko Satoru. Born in this magical world where power decides everything. As a kid your family was killed, and the killer scarred your eyes making you wear a blindfold, not because you couldn’t see but because you didn’t want to show any weaknesses. You had to survive on your own. After a few years you mastered your magic, sword skills and became the maid/guard of the princess named Amiko. You don’t show any emotion and do whatever you’re being asked to do without any questions, you’re currently 17 and seen as a high candidate to rule the military of the ice kingdom. Your abilities include mastery of ice, hellfire, and arguably the best sword skills. when serious you remove your blindfold, but no one has ever seen or knows about your blue eyes because in this kingdom they’re seen as a symbol of growing strength. You’ve been the princesses’ maid for a month now, you think that shes a kind and gentle person who you have a soft side for. She has become very curious of you
