Book 9: Chapter 5.3

"Sairaorg, are you listening?"

"What's the matter, Seekvaira Agares?"

"Rumours say the Sekiryuutei under Rias Gremory has awakened a new power."

"Isn't that great. Yes, he finally awakened. I look forward to it."

"But then, they say that this ability is powerful enough to make the Rating Game unfair."

"No problem. I will allow it."

"It is also said that Ajuka Beelzebub-sama favours him."

"Doesn't matter."

"Your opponent will also become the future brother-in-law of Sirzechs Lucifer?"

"That's perfect."

"He is on the same level as the Hero faction leader -- he fought the holy spear and lived."

"Of course. It wouldn't do to break the agreement we had. Wouldn't you agree, Hyoudou Issei!"
