Tokimeki Tonight

A sprawling generational saga, this manga follows the Etou family across three generations. The opening arc centers on Ranze, an otherwise ordinary high-school girl save for one notable exception: her father is a vampire, her mother is a werewolf, and she herself possesses inherited magical abilities. Exiled from the magical world to dwell among humans, her family now serves as guardians of the gateway connecting the two realms. The narrative truly takes flight when Ranze falls in love with a human boy—a relationship her parents strictly prohibit. Subsequent story arcs shift their focus to Ranze's brother and, later, to her own daughter.
