She bears a great resemblance to her mother, but there are a handful of differences. Her hair is pure black, as opposed to her mother's dark brown hair. She has blue eyes like her father, while retaining her father's red eyes when she gets excited. She also has a larger bust and is taller.
Despite the similar appearance, she is very different from her mother. When she first appears she's shown to be rather ditzy, mainly for walking into a door because she thought it would be automated, and making various comments about the younger versions of people she knows. Besides this she is mostly friendly and not overly serious. She also appears to be attracted to women and when she gets excited by them she, like her father, has nosebleeds.
Vampiric Abilities: As a vampire, she possesses superhuman strength, speed, reflexes, and durability. Her regeneration was demonstrated when a dragon stabbed through her stomach with its tail and she had recovered within a few minutes.
Magic: She has demonstrated using magic like her mother.
- Hasta Aurum / The Golden Spear: It is an intelligent-type weapon capable of producing and manipulating lightning. It's appearance is almost identical to her mother's Schneewalzer though her's is gold while Yukina's is silver. So far, she has demonstrated the ability to turn the head of the lance into lightning and have it wrap around her target while still being able to cut things.
I, Sword Shaman of the High God and priestess of the Lion, beseech thee. Dawn light of exorcism, spirit wolf of snowy mist, grant me the divine might of thy steel, that I may smite a hundred evil spirits!
