As Sylph explores the dungeon's treasure room, Yuno is drawn to a scroll containing mysterious writings. As he reads the words, his grimoire and the scroll begin to glow, and the writing disappears in a flash of light.
Desperate to save Asta from Mars, Yuno breaks free of his restraints and struggles to find a spell to help him. Time seems to stop and Sylph appears next to Yuno. She yawns and then blows a kiss towards Laevatein, breaking the sword and throwing Mars into the wall. Yuno then notices Sylph's disappearance and the appearance of the scroll's words in her grimoire.
Returning to the capital, Yuno shows her grimoire to Julius Novachrono, who is able to read a bit of Sylph's entry. He asks for a demonstration, but Yuno admits that he hasn't been able to summon her again. Disappointed but intrigued, Julius tells Yuno to treat her well.
