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 dedicated 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 on September 3rd, 1989, as the only child of her father and her mother, Sayuri Tenjo. 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 Nanako was against it as she thought devils were creepy. Despite that, Morisawa began staying over more frequently at Sayuri's house and began spending more time playing with Nanako as an effort to become closer to her. 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 don't die if they aren't shot in the head, so he snatched the gun from Sayuri, shot her dead and raped her as he simultaneously sucked her blood. 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. 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 moan her name since she knew who he actually wanted.

Left orphaned, Nanako was adopted into the Chizu household by Kousuke Chizu. Even after being placed in a new, safe environment, 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. The time she first met Kikuhara was in high school, at one of the study groups put on by her foster father, but she didn't talk to him at the get-together because she was busy studying for her high school exams. Another time when she went to turn in a mock test to her foster father, she ran into Kikuhara who had fallen asleep in the study room. When Nanako attempted to find her father, 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 close during their study sessions. Nanako thought he was nice and strange, but the fact that he was not overly friendly and didn't help 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.

The day Nanako's results came back, she rushed to a cafe and ended up getting there before Kikuhara. As she waited, she saw an incident with a devil taking place outside, to which she realized that Kikuhara was a devil officer in action and that he was in the police department. This revelation made her devastated, as she fell for another police officer. Kikuhara knew the what she was feeling, so he came to visit Nanako who had holed herself up in her room. Nanako initially didn't want to talk to him and was very upset at him, but Kikuhara didn't give in. He came clean about his job, and explained that the fact that Morisawa was a devil was unfortunate, but unless 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). This brought her great comfort, as even though she liked Morisawa, he wanted her as a woman which Nanako didn't want. When Nanako thought she understood, she joined the CCC and fell in love with Kikuhara in the process with no reciprocated feelings. With doing so, she also 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 black-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 as she brutally killed several devils out of pure hatred. She was also very devoted to exterminating every single devil in society. She didn't feel any remorse or guilt, as she didn't see it as killing, she saw it as pest-control. Although she is a calm, quiet and a level-headed, physically capable fighter in most situations, she is also seen to be very emotional and straightforward. She wears her emotions on the sleeve and easily lets out her emotions, be it anger, fright, relief, or sadness. 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 is caring and considerate of others, especially her allies such as Kenichi (Zero 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 co-exist despite being a human/devil relationship. She becomes more helpful and kind towards the group, and is seen to apologize for her past behavior and actions. 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).
