Tsukiyo Kujyō (九条 月夜 Kujō Tukiyo) is a lover of the moon and the 8th holder of a Runaway spirit. In addition, she is the holder of the third revealed goddess, Vulcan.
Generally, Tsukiyo shows no interest in people whom she considers "not perfect" in her world and would ignore them. Her trusted doll and only friend is Luna which she's dreaming to go to the moon with one day. She is also shown to sleep with Luna. After her conquest, Tsukiyo was thought to be the same but she has shown signs of change. When she found out about the rumors of Kanon and Keima, she briefly returned back to her old habits.
Tsukiyo has demonstrated adequate skills in handling a telescope, as she have been using it for a long time. It remains unknown if she has good grades in school as she has never been seen in class in the manga.
Tsukiyo has long, orange-blond hair that flows down with two princess curls of hair draping the sides of her face.
Tsukiyo is usually depicted wearing her school uniform however, her uniform's inner shirt is a darker color, her skirt has a dark frill, and like Kanon in the anime, she wears a gem around her neck. It is very much unknown what she wears in her daily life although she is shown wearing doll clothes made by Elsie when she shrunk. She also owns a raincoat for rainy days.
