Seifuku no Vampiress Lord

Irie Yuunagi is an ordinary high school girl whose life takes a drastic and irreversible turn one fateful night. While going about her routine, she is suddenly attacked by a mysterious man who drains her blood, leaving her unconscious. When she finally regains her senses, Yuunagi discovers that the encounter has fundamentally altered her existence—she has been transformed into a vampire. The stranger responsible for her condition introduces himself as Rin, revealing that his bite was not merely an act of feeding but a formal initiation. By turning her, Rin has effectively bound Yuunagi to his own household, adding her as a new member of his vampire family. Thrust into a hidden society operating entirely outside the boundaries of human knowledge, Yuunagi finds herself completely unprepared for her new reality. She must now navigate the complexities of an unfamiliar world while grappling with the sudden loss of her humanity. With no way to return to her former life, Yuunagi relies on Rin to guide her through this daunting transition. He begins to instruct her in the strict laws and customs that govern their kind, forcing her to adapt quickly. As she learns the intricate rules of the vampire world, Yuunagi must reconcile her past as a normal student with her newfound identity under Rin’s watchful guidance.
