Y/N got adopted into the family of devils but he doesn't know it and neither do they know that he is aware of supernatural and has not 1 but 3 sacred gears. Harem story + other characters.

Emily and Tracer have been together for a while now to where they were living together in an apartment near King's Row. One day though Tracer was out on a mission leaving Emily alone for a week. During this week she makes friends with a peculiar man who used to live in New York, but moved here for university. When Tracer comes home she meets this man to become close with him as well. Tracer won't need to always wear the thing on her chest, only when she is fighting. Tracer in 23 years old, Emily is 24 years old, and (Y/N) is 22 years old.

I saw that she had no fanfics about her and quite frankly i didn't like that so I'll be trying my best to make this.
