Sayo Hitsugi

Sayo Hitsugi is the head nurse at Mochizuki General Hospital as well as one of the members on team Ampule Zero who is the close combat expert of Black Label, handling miniguns and general-purpose machine guns with ease. She's also incredibly strong and has a good memory. While normally nice and laid back, on a mission, she wears a devil mask and armored gauntlets and turns berserk, showing her more brutal and sadistic side. Sayo is a slightly tall, lean built woman, who has lightly colored skin, with long blue hair and eyes that are violet. Her bangs are shorter and go off to the side of her face. Behind her bangs is a grouping of hair that is longer than her bangs,but not as long as her actual hair. Along with other female members of Ampule Zero, Sayo has an above average bust size (94 cm). Sayo tends to wear a nurse's outfit, but is seen wearing other clothes as well. She is usually seen wearing headphones when she is dressed more casually. Her style of clothing mostly consists of punk fashion such as fishnet stockings and or raggedy tank tops. Sayo always wears a mask when completing a Black Label mission. The mask gives Sayo a demonic appearance, especially when she is carrying heavy weaponry. Sayo is a harsh nurse that also shows no mercy on missions. Without any hesitation she pointed a minigun at point blank range and fired at a guy, killing him instantly. Sayo obeys her orders flawlessly earning respect in the eyes of her comrades. However, she can get a little hotheaded when she is at risk of injury. Despite the fact that Sayo has her merciless and aggressive side, she also has a kind and thoughtful side, which is shown when she invites Arashi Mikami to the bath with the other Ampule One members after their mission was complete. In Episode 8 of the Anime adaption, She passionately kissed Arashi for saving her, hinting she harbors romantic feelings for him, without realizing the difference between their ages. In Episode 10 of the anime adaptation, she openly admits that she loves Arashi in front of the rest of the girls of Black Label.
