Biography
After defeating a foreign invasion, Jack returns to the Royal City with Julius Nova Chrono 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.

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