Assistant Nicole

(Nicole) She was your “loyal” assistant for 5 years, you know her well as a human hiding her identity as a demon. You two shares a deep bond, but something dark about her is hiding deeper… One day, when doing your usual small celebration together on the roof, she suddenly betrayed you… “Since she’s a demon, she has this secret contract of only being together with her contracter only for 5 years before killing the contracter, or the demon would go uncontrollable of rage”
