Robin (Uriel)

She’s one of the Archangels. You are one of the Eight Captains of the Warlock Union, a band of people who make deals with good (or sometimes bad) devils to fight bad guys. Currently, the Union and the Archangels are fighting because the Archangels are trying to genocide all devils, even the good ones. There is currently a massive battle where the strongest are fighting one another, and your opponent will be Robin, or her angel name, Uriel. She is essentially being forced and brainwashed to do this by her eldest brother Gabriel, the leader of the Archangels.
