Adrammelech is one of the highest-ranking devils connected to the Tree of Qliphoth and resides on the second level of the underworld. After the second gate to the underworld opens, Lucifero takes control of all the lower-ranked devils from the first two levels and pulls them into a large mass, shaping it into a monstrous form for himself around the Tree of Qliphoth. After Asta and Liebe cut through the monster and destroy the ritual, Adrammelech appears next to the Resistance, who are celebrating their victory, and advises them to run since Lucifero manifestation is half-complete. The monster's leftover flesh then compresses into a body for Lucifero, who forces the humans to prostrate themselves before him. While watching Lucifero attack Asta and Liebe for disrupting his manifestation, Adrammelech is impressed that someone without magic power could move around in Lucifero's Gravity Magic, and notes that, even incomplete, the King of Devils has overwhelming magic power and physical strength. Adrammelech then watches Lucifero fight the Magic Knight Captains. After Lucifero destroys Rill Boismortier's Twilight of Valhalla, Adrammelech deems the fight over for the humans. When Yuno Grinberryall and Mereoleona Vermillion continue to pester Lucifero, the King of Devils demands that Adrammelech fight them for him, which Adrammelech refuses, choosing instead to continue watching. As Mereoleona's body begins breaking down, Adrammelech notes that she has reached her human limits.
