Rosen Blood, Vol. 4 (manga)

Rescued from a horrendous carriage accident, Stella becomes imperiled by her saviors-a group of impossibly gorgeous young men who thirst for her blood. After a horrific carriage accident, Stella Violetta awakens in a Gothic mansion to find that her saviors are gorgeous young men. The manor's residents let her stay as a maid, but Stella soon realizes that their allure hides a savage thirst.

Desperate for Stella's affection, Yoel stabs Levi, who reconsiders his desire to protect the other nonhumans. Stella searches through Rosemary's notes to find a way to awaken Yoel after the incident and uncovers clues about why Levi's been shedding tears of blood. Are any of Rosemary's "children" really capable of love?
