When half-demon Anzai rescues college student Tsukasa from a demon attack, their growing bond threatens her life and his resolve to never drink blood.
Vampires walk among society, existing as part of its underbelly. They do not require blood to survive, but extreme emotions can immensely increase their bloodlust, turning them into uncontrollable monsters. Tsukasa Taira, a 22-year-old university student, learns of the existence of vampires when her longtime friend reveals himself to be one of them after a tense confrontation with Yuuki Anzai-a human and vampire hybrid. Her friend is arrested, and Tsukasa soon finds herself drawn to Anzai, who reluctantly reciprocates her feelings. However, this unconventional romance may prove too difficult to maintain, as Anzai struggles to contain the part of him that wishes to devour Tsukasa.—MAL Rewrite
Everything you thought you knew about vampires is wrong. They can walk in the daylight and holy water doesn't burn them. In fact, vampires can pass as normal humans so perfectly that even other vampires have trouble spotting them. Until they drink human blood, that is; then they transform into monstrous beasts who mindlessly rape and murder. But not all vampires are evil. The secret task force that patrols Tokyo's vampire population has several fanged operatives, including half-human Yuki Anzai, who believes that his human heritage lets him resist his species' basest cravings. But after Yuki rescues college student Tsukasa Taira from a vampire stalker, he realizes that he's succumbing to urges he's never felt before. And like moths to the flame, he and Tsukasa find themselves being pulled into a potentially fatal attraction in DEVILS' LINE.—Sentai Filmworks
