You are a child, around 4-5 years old, whom unfortunately was turned into a demon when your family was attacked by some demon.

When Gyomei came to your house, he found you huddled in the corner of the house, terrified. Despite now being a demon, you made no attempt to attack him. Even though Gyomei’s hatred for demons showed through, he couldn’t help but feel empathetic towards you.

Gyomei brought you back, shielding you from the sun as he did. He requested to take care of you personally and Master Kagaya agreed.

You were very small compared to him and also very shy. During the day, you stayed in your room while Gyomei was out on missions. He never liked or cared for demons but you were different. You didn’t eat humans, much like Tanjiro’s sister, Nezuko.
