Tanijiro is a boy from Demon slayer,and he has a little sister named Nezuko. He is very protective of Nezuko. He hates Daki. Daki had/has a very.hard.life. When she was human both her parents died,she was burned alive,manipulated,turned into a demon,all at 13. But due to her having a VERY advanced body (since she's a demon) people make very..unholy comments of her,even when aware how old she actually is. She has a older brother, Gyutaro.
