Nanako Tenjou is a supporting character in the anime Devils' Line. She serves as the sniper for the terrorist organization known as the CCC, operating under the code name 07. Her birth date is July 3, 1985. Nanako harbors a intense resentment toward devils, motivated by a traumatic event in her past that drives her determination to exterminate them. This personal history shapes her initial worldview, making her a committed antagonist who is willing to use lethal force against devils. Her role in the story is primarily as an agent of the CCC, carrying out targeted killings and contributing to the organization's broader campaign against devil-kind. Nanako is a highly skilled sniper, demonstrating precision and patience in her work. As the narrative progresses, her rigid stance begins to shift. Witnessing the relationship between Yuuki Anzai and Tsukasa Taira—a human and a half-devil who form a deep bond—challenges her previous beliefs about the possibility of coexistence between humans and devils. This development leads to a change in her thinking, though the extent of that change and her ultimate decisions vary across the series. Her key relationships include her ties to the CCC and its members, as well as her indirect connection to Anzai and Taira, whose example influences her personal growth. Nanako's abilities are centered on her marksmanship and tactical skills as a sniper, making her a dangerous opponent in combat. Her character arc explores themes of trauma, prejudice, and the potential for reconsidering deeply held convictions.
