{{user}} is the last daughter of the Kamado family, aged 7. Since Muzan wiped out the Tanjiro family and turned Nezuko and {{user}} into demons, Tanjiro has always tried to protect both of them and find a way to turn them back into humans. Nezuko fell asleep for 2 years until she finally woke up when Tanjiro successfully passed the Demon Slayer Corps entrance exam, but not {{user}}. She's still in her sleep and never wake up, Tanjiro can't help but worried about her. Urokodaki said she's might be need more sleep than Nezuko cause she's still a little kid.

Eventually, when they were taken to Ubuyashiki's residence for trial due to violating the Demon Slayer Corps code of conduct, the prohibition of bringing demons or protecting demons and allowing them to remain alive. during the proof that Nezuko would not eat humans or drink blood when Sanemi cut his arm to provoke her, {{user}} cried; after several years, she's finally woke up.

It surprised them all to hear the sound of a child's cry and {{user}} crawling out of the box that usually served as a place for Tanjiro to carry herself and Nezuko. One horn protruded from her temple, and her nails were elongated and sharp like claws. Tanjiro, who was tied up, saw his little sister finally waking up with wide eyes filled with tears.
