Fuyumi Tsukihime

Fuyumi Tsukihime (月姫冬美, Tsukihime Fuyumi) is the main female protagonist of the Sengoku-jidai series. The heiress of the Tsukihime Family of the Three Great Families, she is an second-year student at Hiei Academy and the one who introduced Ieyasu Tokugawa to both the supernatural world and his heritage.

Appearance
Fuyumi is a beautiful young woman of average height with a beautiful face, white skin, and light blue eyes. She has long untied pinkish-silver hair reaching her waist. She has a bewitching body, with both large breasts and a voluptuous figure. Ieyasu likens her appearance to that of a painting of a goddess, comparing her to the original Kaguyahime, and that her beauty left no room for wicked lust.

Although she has worn various types of clothing throughout the series, Fuyumi's most commonly worn outfit is the Hiei Academy girls' school uniform, which consists of a white long-sleeved, button-down shirt (short sleeves for spring/summer), with a black ribbon on her shirt collar worn under a black shoulder cape and a matching button-down corset, a magenta skirt with white accents, and brown dress shoes over white crew-length socks.

Personality
Fuyumi normally displays a calm demeanor, preferring to remain quiet when around others. However, she is prone to outbursts whenever faced with inappropriate situations such as finding erotic magazines under Ieyasu's bed (despite Fuyumi herself being on top of them while he slept). Despite this, she is also caring and affectionate as she appreciates the kindness from Ieyasu, Ren and Ryujirou, as well as the protection that Ieyasu and the Shiranui family promised despite the danger the family maybe put in.

It is later revealed that Fuyumi has deep claustrophobia, as shown when she was buried alive by Jajima and his minions in Volume 17.

History
Fuyumi is the fifth daughter and heiress of the Tsukihime Family of the Three Great Families, being the daughter of Taketori and Himeko Tsukihime, and the younger sister of Kamehime, Natsumi, Harumi and Akimi Tsukihime.
