"He was the mastermind behind the assault the other day. ……Lucifugus. Yeah, he’s someone related to Grayfia-san. What’s shocking is that he’s her actual brother. ……The higher-ups of the Devil’s side are in a stir due to his appearance. After all, there’s someone else besides Grayfia-san who is a survivor from the House of Lucifugus that directly served the former Lucifer. I heard that Grayfia-san is currently being asked questions. ……It’s regarding about how Euclid is alive. So that must mean that the higher-ups are suspicious of Grayfia-san and thinks that she lied about his death. ……There’s no way that Sirzechs-sama will doubt Grayfia-san, however the higher-ups are different. They must be feeling uneasy so that’s why they are questioning Grayfia-san. Especially, cases regarding “Lucifer” are treated as a totally different story in the Underworld, regardless of the “Old” or the “New” one."
