Mitsuba Sangū

Mitsuba Sangū 「三宮 三葉, Sangū Mitsuba」 is a member of the Japanese Imperial Demon Army's Moon Demon Squad. Later in the series, she is promoted to second lieutenant.

Appearance
She has bright golden blonde hair tied up in pigtails and big blue eyes. She's seen always wearing her uniform, which she wears with her sleeves rolled and with fingerless black fingerless gloves rather than the standard white, and also a black cape with a green underside. She has large breasts.

Personality
Sangū is shown to be a serious and by-the-book soldier who dislikes those who break the formation and commit to individual action. The source of this is revealed to have been from guilt stemming from an incident that happened in the past where she once broke the formation of her team in order to save a teammate, which caused their leader to die while saving her life. Also, because of this, she didn't want Yūichirō to save her when she was caught by the vampires, thinking that he would die if he tried.

While she shows a complete dislike towards Yū, Shinoa hinted that she is actually falling for him. However, this is yet to be confirmed.

History
Sangū joined the annihilation force when she was thirteen. When her comrade Shirō was in danger, she broke formation to save him from a horseman of the Apocalypse. When she slashed its arm to save Shirō, the monster used its other arm to strike her, but her squad leader saved her by using himself as a human shield, which caused his death.
