Kuina Ubuyashiki

Kuina displays her strong sense of loyalty and devotion to her brother as the new head of the Ubuyashiki Family and leader of the Demon Slayer Corps by being the one to forcefully remind him of his duties as their leader. She even resorts to physical force to remind him of this by slapping him, in order to ensure he did not break down under the stress of his responsibilities.

Kuina is a girl with light, pale skin with a set of large, purple eyes. She wears a white blunt bob hair with fringe covering her forehead. She also adorns an elongated wisteria headpiece on the left side of her head. Kuina is usually seen wearing a purple, flower-patterned Edo komon kimono with a white juban under it. She also wears a black obi with a white obiage under it and a pink obijime it.

Extraordinary Memory: During the infiltration of the Infinity Castle by the Demon Slayer Corps, Kuina displays exceptional memory and skill in map making, having successfully mapped out and memorized the entire structure, despite the castle constantly changing. She also provides real-time logistical information to the Hashira alongside her sister, aiding her brother in planning the route to Muzan Kibutsuji's location.
