Diabolik Lovers

Yui Komori lives with the Sakamaki brothers in their secluded mansion, located in a remote area. The six brothers, Shuu, Reiji, Ayato, Kanato, Laito, and Subaru, are vampires, and they're confused about why their father sent Yui to live with them. She's intended to be their "sacrificial bride," and her arrival sparks both sadistic and carnal intentions from the brothers. As Yui interacts with each brother, she questions her father's decision and starts to feel an inexplicable pain in her chest.
