I said people who's abilities fall under darkness, but what I should have said is "people who's spirit lies on the dark side". That's dark, not evil.

The current list of people it would effect are:

Seriel and Samiel as Fallen Angels
Evelyn and Rebbecca
Christoph
Kurayami
Lilith
Deathedge
Duatos
Grimm
Ryuu if he's still like he was in Athalia

The current list of people it would effect to a limited extent are:
Rei
Hamlin
Constance

This is just the list of people who would be targeted by the ability. Whether they actually give in to the emotions is up to you.
