Biography
While exploring the dungeon's treasure room, Yuno is drawn to a scroll containing mysterious writing. As he reads the words, his grimoire and the scroll begin glowing, and the writing disappears in a flash of light.

Desperate to save Asta from Mars, Yuno breaks free from his restraints and strains to find a spell to help him. Time seems to stop and Sylph appears next to Yuno. She yawns and then blows a kiss toward Laevateinn, shattering the sword and blasting Mars into a wall. Afterwards Yuno notes the disappearance of Sylph and the appearance of the scroll's words in his grimoire.

Upon returning to the capital, Yuno shows his grimoire to Julius Nova Chrono, who can read a little of Sylph's entry. He asks for a demonstration but Yuno admits that he has not been able to summon her again. Disappointed but intrigued, Julius tells Yuno to treat her well.

During the invasion, Sylph alerts Yuno of Valtos' Blackout, saving him from being scattered with the other Magic Knights. Catherine attacks Yuno and removes most of his senses with Joyful Destructive Ash, but determined to keep up with Asta, Yuno summons Sylph and uses Sylph's Breath. The spell blasts Catherine into a tower, and Yuno realizes that Sylph has been showing him where the mana is. She hovers near Yuno as he chases after Catherine and saves Charmy Papittoson's food.
