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). 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.

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).
