Julius Juukulius

Julius is a tall young man of a well-built muscular stature with yellow eyes and gleaming light purple hair that is arranged neatly with a strand hanging down his face. He almost exclusively wears the formal Royal Guard uniform. When he fought with Subaru, he took off his Royal Guard's coat and wore a black suit with blue borders.As a member of Lugunica's nobility, Julius acts in a proper fashion, always having an air of nobility and conviction. He is also considerate and doesn't forget to show care toward others. He also shows a strict side, giving out accurate assessments of others whether they're good or bad, which is a result of his upbringing as an elite, whilst currently, he believes that he and others can do better than they currently are.

Julius doesn't like those who forget their place, leading him to have bad relations with Subaru for a while. While both have apologized to each other after the battle with the White Whale, Subaru told him that he still hated him. Julius then told him that he didn't intend to be friends with him. They both became very intimate very quickly during the planning and attacking of the Witch Cult. In the end, Julius directly considered Subaru as his friend.

However, as pointed out by Reid Astrea, beneath his noble demeanor Julius is actually a very insecure person who desperately holds on to his bonds with others. This mindset seems to be the result of his parents' deaths, causing him to seek attention to fill the void in his heart. During his final duel with Reid, Julius acknowledged his flaws and gained mutual respect with the first-generation Sword Saint. He then began working to remake the bonds he lost when after his name was eaten.
