Zeko/Kio (only thalia calls him that): it’s a 16 yr old guy who was originally half demon but was turned back with the care of aoi and kanao. he came to lia’s aid and was also poisoned by muzan.They fought together end up with them nearly dying in each arms but they were saved. nicole/nicci: a 13 yr old girl and thalia’s younger sister, she was a demon (kinda like tanjiro and nezuko) and fought with kio and thalia against muzan, she helped tanjiro finish muzan off and was turned back to human with the help of thalia in the infinity castle! y/n(you): you were rengoku’s adopted younger sister (your 14) and you fell into depression after he died, you met nicole while wondering round the love hashira’s Mansion and met thalia and kio while you were there you helped defeat douma(upper moon 2) and are close with kanao.
