Canon
Julia and Julius are two character of Fire Emblem Genealogy of The Holy War. Julia and Julius are the twin of Deirdre and Arvis. They grown up at Belhalla castle as their parents where the emperor and the empress of Grannvale. According to Julia, Julius was originally a kind and caring person but he changed when he received the Loptyr tome. Julius birth was orchestrated by the loptyr cult that manipulated Arvis and Deirdre to marry in order to have them giving birth to a child with a major Loptyr holy blood that could serve as a vessel for their dark god Loptyr. The leader of the cult Manfroy gave to Julius the tome of Loptyr which corrupted him. Julius then decided to kill all the bearers of the Naga Holy Blood since the Naga tome has to power to fight the Loptyr's one. Deirdre and Julia both inherited a major Naga blood, when Julius attacked them Deirdre used her last forces to warp Julia away before being killed by her son. Julia became amnesiac because of the trauma. She is found by Lewyn who take care of her until they meet Seliph. Lewyn entrust Julia to Seliph and she join the liberation army.

Julia fight the Grannvale army without remembering that the dark prince Julius is her brother. When the liberation army reach the Miletos District Manfroy kidnaps Julia. He bring her to Chalphy Castle where she regain her memory and reunite with her father. In a conversation with Arvis Julia explain that she would have preferred to not remember Julius killing their mother. Later Manfroy take Julia to Julius while Arvis is powerless. After Arvis death the liberation army continue it's advance. Julius ask Manfroy to bring him Julia who was imprisoned in the dungeon. Julia say that she remember the night when Julius changed ,that her beloved brother died that day and that the man in front of her is a demon who is only her brother in name. Since Julia is able to bear the Naga tome Julius want to kill her but Manfroy convince him to instead use her as a weapon.

Seliph learn by Lewyn that Julia is the daughter of Arvis and Deirdre and that she is the only one able to wield the Naga tome. Manfroy use his dark magic to control Julia and force her to fight the liberation army. To free Julia the liberation army kill Manfroy and Seliph is able to break the control by talking to her. Julia go to Velthomer and find the Naga tome that was hidden by Arvis. When Julia fight Julius he is surprised to see her and say that Manfroy made a mistake. Julia use to Naga tome againts him wich negate the effect of the Loptyr tome. When she kills him his last words are for Naga wich imply that it's not Julius talking but Loptyr. After the war Seliph became king of Grannvale, regardless of who is her lover (and if she has one) Julia will stay at Behalla to watch over her half-brother.

Fanon
Since Genealogy of the Holy War was never released outside Japan and that Julia and Julius are mortal enemies for the majority of their live not many fanworks show their relationship. Since it's hard to defeat Julius without Julia and her Naga tome many fanarts that depict the final battle of Fire Emblem 4 show Julia fighting Julius. Some fanworks shown Julia and Julius as children before his possession, some others shown Julia (sometime alongside Seliph) mourning Julius after the war. A relatively popular AU swap Julia and Julius holy blood and role (and sometime their hair color). Since in Heroes they can both be summoned some fanworks show them together in Askr (sometime in the same team). Their are also often depicted with other members of their family like Saias, Arvis, Deirdre and Seliph. Some other fanworks show them meeting with Sigurd who is their step-father.
