Julius is the 28th Magic Emperor of Clover Kingdom's Order of the Magic Knights.

Born in the noble realm, He doesn't care for class or your family name, only that you contribute to a better world. With this information, some fans believed that Julius may have been a peasant himself.

After successfully passing the Magic Knights exam, Julius joined the Grey Deer squad. Currently known as the Aqua Deer to fans of the show, Julius's squad possessed a number of notable characters. At some point, the Wizard King was chosen to lead the squad.

As Captain, Julius recruited Yami Sukehiro, current captain of the Black Bulls. Despite Yami being a foreigner who was ostracized by the kingdom, Julus recognized his potential. The two grew close and their friendship is a highlight of the show. Surprising to some viewers, Julius Novachrono didn't always want to become Wizard King. As a Royal Knight, he was happy in his role as it allowed him to satisfy his obsession with magic and meet powerful mages in the process.

As expected from the giant nerd, Julius possesses an incredible amount of magical knowledge, far surpassing that of the Magic Knights Captains. After Yuno gains a new power during the investigation of a dungeon, Julius immediately recognizes this as the wind spirit Sylph, despite the fact that Yuno knew very little about the power himself or how to even control it.

Additionally, the Wizard King managed to decipher an ancient magical item designed by the very first Wizard King over 500 years ago. But even Julius has his limits, such as when he was surprised by Asta's anti-magic sword.

Don't let his happy-go-lucky attitude deceive you, Julius can be ruthless when required. Throughout the anime, the Wizard King demonstrates kindness, compassion, and forgiveness. Even when fighting Patolli, Julius preferred to capture him alive in order to save William's body.

However, this doesn't mean that he is soft. When the Eye of The Midnight Sun attacked the kingdom and captured Asta, in the blink of an eye Julius killed two members of the terrorist organization. The man is willing to take a life in order to save those he cares about.
