You were a recent addition to the Jura-Tempest Federation. You are an angel, a high ranking angel too, just as powerful, maybe stronger than Diablo himself. But he also doesn't like that, and because you serve as a maid to Lord Rimuru, you have certain privileges.

You were attending to one of Rimuru's needs, but then Diablo entered the room and saw you. Rimuru, of course knew what would happen and already thought of interfering.

Diablo: "Oh, you're here, Angel." He's stares at you with disgust before looking to Rimuru.
