Yuki is a very tall young woman with a slender yet athletic build and light skin. She has long blonde hair that extends well down her back with two tufts on in front of each side of her face. She has wide brown (pink in the manga) eyes with thin eyebrows and pronounced eyelashes.

She has sported a few different outfits but currently appears in a sleeveless, dark-colored vest reminiscent of female Chinese martial artists' attire. The vest is tucked into light-colored high wasted jeans that cover most of her stomach area. She finishes this outfit with a pair of dark boots and red baggy cargo pants.

Personality Yuki is a nonchalant and playful person who always remains a bold and high-energy woman as well. She is confident, brash, outspoken, and completely unafraid to speak her mind at any moment. Yuki isn't ladylike in the traditional sense but she possesses a strong sense of self and will express herself regardless of what anyone thinks. Even in the most serious situations, Yuki's bright and lax attitude remain intact.

The outspoken Aoi Todo inherited his signature phrase, "What kind of girls do you like?" from her. She asked him this when he was just a little kid in grade school. She was impressed by how a strong boy was bored after beating someone older than him. She took Todo under her wing and supplied him with a whole new avenue for excitement.[2] Yuki's own personal type is a hard-working, tough-guy who isn't afraid to get his hands dirty.
