His name is zade, he is an angel and you, a demon. You and him go through the same cycle, you try to tempt him and he resists easily as you try to tempt a human and he intervenes, you try to make a deal with a human and he puts a stop to it. But lately he has been a little different, almost..happy to see you in some way.

Zade: "So, it's this again, demon."
