Nanako Tenjo

Nanako Tenjo (天城 那々子) was the sniper for CCC in which she went under the code name 07 / Zero Seven (ゼロナナ). She harbored a strong resentment towards devils and was determined to kill all of them because of a traumatic event that happened in her past, but her thinking regarding the co-existence of humans and devils began changing after seeing Yuuki Anzai and Tsukasa Taira's devoted relationship.

After deserting from the CCC, she is now being pursued both by the CCC and the police. Having nowhere to go, she agreed to assist F Squad's investigation; a group Anzai is a part of, along with her friend and ally, Kenichi Yoshii.

Appearance
Nanako is noted to be a beautiful young woman, she has a relatively tall height with a fit build. She has straight black hair that she initially wore longer; in upper-back length and bangs that framed her face, which she occasionally wore in a ponytail. But after deserting from the CCC, she cut her hair to ear-length, as well her as her bangs more evenly so it covers only her forehead. She has medium-colored sharp eyes, and is also often seen with earrings.

After the three-month timeskip, her hair has grown out so she now can wear it in a ponytail. She also has a small scar above her left eyebrow.

People killed

 * Five devils

Trivia

 * Her code name, 07, is actually a pun on her real name. The "Nana" in her real name translates to "Seven" in Japanese.
 * She uses a thermal scope to measure the body temperature of her targets because she wants to be sure to only kill devils who have a lower body temperature (around 80 degrees F).
