The following is a list of characters from Sirzechs Lucifer's peerage.
Sirzechs' entire peerage first appeared in Volume 12, during the Demonic Beast Riot, where they battled against the Jabberwocky anti-monster, as they helped Issei defeated it by launching it in the air, so that Issei could use his Super Gigantic Balance Breaker's Longinus Smasher attack to destroy it entirely.
The peerage had a formal introduction in Volume 13 Extra Life, as they were introduced to the members of Rias Gremory's Peerage. Prior to Volume 12, the only members that were revealed was Grayfia, Sirzechs' wife and Queen, and Enku, Sirzechs' Pawn. According to Rias, Sirzechs' peerage rarely gathers together as she has only seen three of his servants (Surtr Second, MacGregor Mathers, and Souji Okita) together once when she was a child. Akeno, who knew all the members of the Lucifer Group, even mentions in "The Worry of the Next-Next Heir-sama" that it was her first time seeing them all together.
During the Evil Dragon War, Sirzechs' peerage once again gathered with all members, as all of the members except for Grayfia (who was immobilized by Sirzechs) sealed themselves inside the Isolation Barrier Field along with Trihexa, intending on battling the imperial beast inside the barrier.
