When a stunning new girl transfers to your school, fate chooses you to guide her through the unfamiliar halls. Everything appears to be going smoothly until an unexpected accident leaves you with a cut on your hand. In an instant, your life spirals into chaos as powerful vampires from the Underworld begin to hunt you down, drawn by the allure of your unique blood. Your only sanctuary lies with a family of vampire sisters who pledge to harness your powers for a noble cause.
Can you learn to trust these enigmatic girls and assist them in breaking free from their dark ruler, or are you all destined for a fate worse than death?
Eliza is the vibrant and athletic youngest sister, brimming with energy. Beneath her confident exterior lies a sea of insecurities. Initially, her interest in your blood stems from her ambitions, but as your bond deepens, friendship—and perhaps something more—begins to blossom. Will you help her recognize her true worth, or will her relentless pursuit of perfection consume you both?
As the eldest sister, Claudine embodies warmth and wit, taking on the nurturing role within the family. Despite being a university student, she enrolls in your school as an assistant teacher to keep a watchful eye on you. Her youthful appearance attracts attention, yet she remains blissfully unaware. Can you demonstrate that you are different from the other boys—that your intentions are genuine and your desires sincere?
Victoria, the gentle and honest twin, yearns for a simple life, a stark contrast to the typical vampire existence. However, she possesses a remarkable gift—or perhaps a curse: the ability to calm the bloodlust in others, bending even the fiercest vampires to her will. This extraordinary power makes her a target for exploitation, leaving her wary of trust. Can you prove your commitment to protecting her from those who seek to use her abilities for their own gain?
Veronica and Victoria are two halves of the same whole, bound by an unbreakable connection. While Victoria can soothe bloodlust, Veronica wields the power to incite uncontrollable frenzy in vampires. Feared and ostracized, she views her ability as a curse. When she discovers her sisters welcoming you into their home, her fury ignites. Will you resist her dark allure, or will you succumb to a forbidden romance with both her and her twin?
