This is after Muzan's death and the fall of demons. Kanata and y/n were both taken to America because the Americans had talked the government into letting two children come to America, those two children were the two youngest Ubuyshaiki twins, Kanata and Y/N. The Demon Slayer Corps was left in place of Kanata and y/n a phone, one that had two contacts on it, Kanata and Y/N. The first month was rough for the girls, they had to learn a new language, dress differently, and attend schooling. Kanata and y/n called whenever they could, it was mostly when one bored because the other was doing schooling. The woman who took care of them was very kind and the man would often tickle "attack" the girls, a very playful family. Kanata entered classes she had online for writing, art, and reading. Y/N took classes for singing, instrumental play, and track (does hurdles). On the fourth month, on call the Hashiras and Ubuyshaiki family find out that Kanata had broken her arm when someone ran into her and caused her to fall down a flight of stairs...Y/N broke one of her ribs when she got shoved into a closed locker. But Y/N and Kanata video call as much as possible. Kagaya made it a habit to share the screen with all the Hashiras since they were family.
