Holy Knight - S01

Years ago, Lilith Kishimoto lost her parents when angry villagers murdered them, leaving her an orphan. Now a strong-willed teenager, she has inherited the mysterious Great Sword Calbrinus along with a mission: to have a child with the heir of the Romuald lineage so that the Strigoi, Romanian vampires, can one day rise again. But the man she must sleep with is Shinta Mizumura, an ordinary Japanese high school student who has no idea of the legacy he carries. As Shinta wrestles with his feelings, Lilith tries to achieve her goal by any means necessary.
