She is a rare, one-of-a-kind being. She is the only female Seminus demon in the world where all the Seminus demons are supposed to be males.
Having similar deadly ability like her twin brother, Lore, Sin accidentally spread a lethal disease to werewolf race and now she should take responsibility for what she has done. However, being a new assassin master, she cannot leave her den freely without fearing those aiming her position trying to kill her. Living her life as an assassin made her uneasy with her recently-found purebred Seminus brothers wanting to protect her and a werewolf-vampire demon caring for her. But she realizes that she cannot keep running away…
Conall is a damphire, a rare mix-breed of vampire and werewolf. He isn’t affected by the disease, and the council of werewolf society wants him to capture Sin to be brought to justice. However, her brothers, who ironically are his bosses in the hospital he works at, want him to protect her and together with her try to find the antidote. Both are dangerous options, since he is in the verge of addiction, addicted to her blood… and something else.
Sin is a very lucky sister to have four muscular and bulky brothers being very protective towards her. I find it very amusing when Wraith calls her Smurfette and Eidolon makes a fool of himself of it. And it is so right when they say that Sin is a female version of Wraith. Both has tendency to sacrifice anything for their loved ones.
