Tsukiko Aido

Tsukiko Aido is the daughter of Lord Aido. Her brother is Hanabusa Aido, which makes her Akatsuki Kain's cousin as well. Little is known about her. She is a Level B Aristocrat Vampire, but it is unknown if she is a student of the Cross Academy. She first appeared when her father wanted to introduce her to Kaname Kuran.

Appearance
Tsukiko has blond hair which is just a bit longer than her shoulders. Her eyes are light blue, just like Hanabusa's and her father's.

Personality
She is almost unknown, but in the few seconds she had in the manga and anime, she seemed a bit shy.

 * "Tsukiko" means "child of the moon" since it is a combination of "tsuki" (which means "moon" or "fullmoon") and "ko" (which is a suffix and means "child (of)").
