Biography
After defeating a foreign invasion, Jack 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, he attends the Magic Knights Entrance Exam and afterwards requests Yuno and passes on Asta to join his squad. He successfully recruits Sekke Bronzazza.

Jack, Nozel Silva, and Charlotte Roselei save Yami Sukehiro from the combined attack of Rhya, Vetto, and Fana. He squares off against Vetto, but when Fana melts Nozel's Silver Spears, Jack teases him and suggests switching opponents, which Nozel refuses. Like the others Jack is surprised when Asta makes it through the battlefield unscathed and lands a hit on Licht.

When Licht's mana is unleashed, Jack tries to attack Licht but the attack is absorbed. When the Third Eye seals Licht's mana and leaves, Jack thinks about how strong they are and says that they are worth slicing up.

Sometime later, Jack is waiting in a room within the Magic Knight headquarters with most of the other captains. While waiting Jack talks with Yami and Gueldre Poizot about the situation with the White Night Eye and about the stars that they all received. When Rill Boismortier tries to defuse the situation with an impression of Fuegoreon, Jack gets angry and tells him to not get carried away just because Rill is the youngest captain in history.

After William Vangeance arrives, Marx calls the captains to the dungeon. There, they listen to Catherine and George name Gueldre as the traitor. Jack says that he knew that Gueldre had his hands in some dirty stuff. When Gueldre runs, Jack activates his magic but is disappointed when Gueldre is captured before he could attack. Jack then watches along with everyone else when they look into Gueldre's mind and find everything that he had done. Julius tells the captains to keep what they have found out a secret. The captains later leave and return to their squads.

Jack is seen with the other squad captains in the star awards festival. He is seen talking to Rill about why the Azure Deer came last. He tells him its his own fault for painting. He laughs at Asta and Yuno's conversion and the emperor losing his temper.

Several days after the Royal Knights Selection Exam, Jack receives an alert from Marx Francois that Julius is fighting Licht.
