Biography
After becoming a Magic Knight, Gueldre uses his Permeation Magic to make deals and to gather information and power, working his way up to captain of the Violet Orca squad.

After defeating a foreign invasion, Gueldre returns to the Royal Capital with Julius Novachrono and other captains of the Magic Knights. They are welcomed with joy and cheers from the Noble Region's citizens.

Several months later, Gueldre attends the Magic Knights Entrance Exam and afterwards requests Yuno and passes on Asta to join his squad.

Before the White Night Eye invades the Royal Capital, Gueldre kidnaps the mages in charge of the barrier.

At a meeting of the squad captains, Gueldre criticizes Yami Sukehiro, Nozel Silva, Jack the Ripper, and Charlotte Roselei for failing to capture any of the White Night Eyes. When William Vangeance shows up late, Gueldre questions how the Golden Dawn develop so quickly, and William responds with a question about Gueldre's trading secret. Yami then criticizes Gueldre's laugh and appearance.

Marx Francois contacts the captains and tells them to assemble in the dungeon. There they listen as Catherine and Georg reveal the traitor to be Gueldre. However, he denies that he would ever betray the Clover Kingdom. The other captains doubt his claim, so Gueldre questions the reliability of Marx's Memory Communication Magic. Yami tells Gueldre to calm down and let Marx read his mind, which worries Gueldre.

Turning himself invisible, Gueldre tries to escape and creates Invisible Soldiers to keep the other captains busy, but Asta is able to sense his location with Ki and hits him with Demon-Slayer Sword, dispelling his invisibility. Angered at being bested by a commoner, Gueldre threatens Asta, and Rill Boismortier quickly restrains the Violet Orca in a painting.

Julius then has Marx display Gueldre's memories and, after dismissing the other Magic Knights, has him continue questioning Gueldre.
