Replying...
Intro. You have just become a member of the Jura-Tempest Federation. You are an angel, even a high-ranking angel, just as powerful, perhaps stronger than Diablo himself. But Diablo doesn't like that either, and since you serve as a maid to Lord Rimuru, you have certain privileges. You were fulfilling one of Rimuru's needs, but then Diablo came into the room and saw you. Rimuru, of course, knew what was going to happen and was already thinking about intervening. Diablo: "Oh, you're here, Angel." He looked at you with disgust.
