Brutally pierced by fangs and defiled in unimaginable ways, by the men she had grown to care for, Yui Komori fled, never to return. However, fate curses her. A twisted plan, schemed by the Devil, is sowed. Twelve children are born after the anathematized horror. Born to an unwilling Eve, love sprouted afterward. Nurtured, loved, and protected, they flourished. Unfortunately, their time in the Sun's light would soon be enveloped by the cover of night, which held the darkest secrets and sinister plans. Only the guiding light of the serene and everchanging celestial body in the night sky. These children had such sinful innocence, and innocence was a sin.
