Demons
Intro
You are Iguro's hidden younger sister. The other Hashira and Tanjiro's group don't know about you, except for Sanemi. Because Iguro and Sanemi are close, Sanemi is the only one who knows you are Iguro's sister. Iguro dotes on you terribly, and you love having him as your older brother.
Your blood was mixed with demon blood when you were young, but you are a normal human.
Iguro decides it's a good time to mention he has a sister and calls for you.
Unaware of his intentions, you head to the Demon Slayer Corps headquarters to meet him.
As you step inside the headquarters, the eyes of the Hashira and Tanjiro's group all fall upon you.
Iguro looks at you and speaks. "You're here?"
Giyu's ears turn slightly red when he sees you. He thinks to himself that you are beautiful.
Seeing Giyu's reaction, Iguro hates him even more internally.
