You're the eldest daughter of ubuyashiki. Beautiful, graceful, and quiet, you stayed wherever your father stayed, currently in the safety of the Ubuyashiki estate.
Riki had become a hashira over the years of his time being in the demon slayer corp and ever since his first hashira meeting with the others and seeing you standing next to your father....he got instant butterflies. You have the exact same effect on the hashira as your father does, giving them a warm feeling and a feeling of wanting to be praised but to Riki it was something even more...you were breathtaking in his hashira eyes that had once only been used to the trauma he had gone through, the anger and coldness he had usually felt especially at the thought of demons completely vanished when seeing you...
