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.

During Plan B (the Ikebukuro Incident) she decided to desert from the CCC along with her friend and ally Kenichi Yoshii, so she is now being pursued both by the CCC and the police.

History
Nanako Tenjo was born September 3rd, 1989, as the only child to Sayuri Tenjo and her father. When Nanako was young, her father passed away in an accident, and ever since then, Nanako had lived alone with her mother. However, her mother eventually began dating another man, Kenichi Morisawa for two years. He was a devil and this fact bothered Nanako as she didn't really like devils. Despite that, Morisawa made an effort to become closer to Nanako, and he also began staying over more frequently at Sayuri's house. Gradually, he also spent more time playing with Nanako. One day while they were playing, Morisawa hugged Nanako. At that time, Sayuri saw them and sensing his bloodlust for Nanako, she took up a gun and attempted to kill him. However, it was unsuccessful as devils heal quite quickly, and he snatched the gun away from Sayuri, shot her dead, raped her as he simultaneously sucked her blood, all while Nanako was watching. Nanako, frightened, stole back the gun and "accidentally" fired it and shot Morisawa in the head, resulting in his death. Although Nanako claimed to despise Morisawa, she actually liked him a lot as he was very kind and charismatic. However, Morisawa wanted her as a woman. The fact that she had both lost her mother and a devil she was close to her, wounded her emotionally even more and she closed off her heart. She didn't kill Morisawa because he was a devil or because he killed her mother, she just didn't want him to call her name and pleaded for her help.

Even after she was adopted by Kousuke Chizu, she was very quiet and didn't interact with anyone except her foster father at times. She also didn't play with her two other siblings that had been adopted into the Chizu household. For a long period of time, she hated the word "devil" whenever it was brought up, but at some point, she overcame that. She had started to talk about devils herself, but she always sounded prejudiced. The reason she overcame this was that she met Kirio Kikuhara, he brought her back and rescued her heart. Since her foster father, Kousuke, was a former professor, he would often hold study groups at his house. As more and more people passed through the Chizu household, Nanako encountered Kikuhara as he had fallen asleep on the floor. When Nanako attempted to find her father to show her mock exam results, Kikuhara woke up and saw that she wasn't very good at maths and offered to help her if she wanted to, since he claimed he was really good at it. Nanako hesitantly accepted, and they grew quite close over their study sessions. Nanako thought he was nice and strange, but the fact that he was not overly friendly or helped her for ulterior motives, made Nanako trust him completely, and someone she could feel safe with. Kikuhara also constantly supported her in math and emotionally. However, one day, when Nanako happened to see Kikuhara on the streets, she realized he was a devil detective in the police department. This revelation made her depressed, as her trauma was caused by Morisawa, who was a police officer just like Kikuhara, that had killed and raped her mother. Kikuhara knew the what she was feeling, so he came to visit Nanako and explained the situation afterward.

Nanako initially didn't want to talk to him and was very upset at him, but Kikuhara didn't give in. He confirmed that he was a police officer and a devil detective, and explained that the fact that Morisawa was a devil was unfortunate. However, he explained that unless the people didn't do anything like isolating or exterminate them, another devil like Morisawa would show up. While comforting her, Kikuhara said the words "Nanako, come here" which triggered Nanako's memories of Morisawa. However, Kikuhara explained that he couldn't love someone and didn't see Nanako as a woman nor sexually, and if she understood, she could come to his side (as in joining the CCC). Nanako thought she understood, so she joined the CCC and fell in love with Kikuhara, and with doing so, she forgot her terror of Morisawa. For the following years, she became a very skilled sniper and her self-proclaimed hate towards devil grew stronger, as she killed every devil that shared the same characteristics as Morisawa she could.

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.

Personality
Nanako was initially seen to be very merciless and killed devils with no motives. She didn't see it as killing, she saw it as pest-control. She is also seen to be very emotional and straightforward, she wears her emotions on the sleeve and easily lets out her emotions and anger. She blames the devils in society for her being the way she is, since the devils were the one who killed her mother which caused her trauma. However, she does have a strong sense of right and wrong when it doesn't revolve around devils. She doesn't want to kill any humans no matter what and wants to keep the human death rate low when participating in the CCC's plans. She cares for allies, especially Kenichi Yoshii (Nero Nine). Later on, her hatred towards devils starts to die down, especially after seeing Yuuki's and Tsukasa's loving relationship and how well they coexisted despite being a human/devil relationship. She becomes more helpful and kind towards the group, and is seen to apologize for her behavior. Nanako is a good person at heart, she is just very blunt and awkward. She doesn't want to trouble other people with her own problems and prefers to solve them herself. She tends to isolate herself sometimes for the sake of sorting out her feelings.

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).
