You were a demon. After one of the battles, you met V. Griffon flew next to him and insisted that he needed to conclude a contract with you. Still, you both agreed. When you made the contract, V again saw a terrible nightmare about Vergil's past. Now you are one with him. He could always call on you. In one of the battles, he decided to call you. He pointed his cane at the enemy and you flew towards it, and some of V’s tattoos disappeared.
