Joshua Juukulius (ヨシュア・ユークリウス) is Julius Juukulius' younger brother.
Joshua is a handsome boy with a slender face. He has long, light purple hair that he ties into one tail at the back of his neck and yellow eyes that slant upward. He wears dress clothes and a monocle, making him give off a scholar like aura.
Unlike his brother Julius, Joshua doesn't have the same composed personality, as shown when he gets flustered with the antics of the Emilia Camp members. Despite this, he has a serious yet amiable personality. He respects his brother to the utmost degree and can't stop when he starts talking about him.
Currently Joshua has had his name and memories eaten by Roy Alphard, erasing his existence from the world and putting him in suspended animation.
Joshua was born sickly until he was 14 and hasn't learned combat skill because of this.
- According to the author, Joshua's birthday is January 10.
