Bianca di Angelo

Bianca was the daughter of Hades and Maria di Angelo, and was the older sister of Nico di Angelo.

History
Not much is known about Bianca's past. She and Nico were born before World War II, so Hades never broke the oath he took after the war to never have any half-blood children again.

Bianca and Nico both lived in Washington, DC at some point. When Bianca was twelve and Nico was ten, both were brought to the Lotus Hotel and Casino by the Fury Alecto disguised as a lawyer. Hades had to erase their memories so they wouldn't know who they were.

After a 'month' in the Lotus Hotel and Casino, which was actually about 70 years, they were taken out by the same Fury. Hades wanted them because he wanted one of them to be the child in the prophecy. Her mother, Maria di Angelo, died when Zeus struck their apartment with lightning while trying to kill Nico and Bianca. The Oracle, showing up shortly after the destruction of their apartment, is cursed by Hades to never have her soul rest, and to stay in her body until it rots. He cursed her because she kept telling him that he should have given Bianca and Nico to Zeus as she knew their future.

The Titan's Curse
Bianca is first introduced in The Titan's Curse, as a Half-Blood of unknown parentage. After being rescued from the Manticore by Percy Jackson and Artemis, Bianca makes the decision to become a Hunter. She shows signs during the quest of being a child of Hades when she is able to slay some of the skeletal warriors easily when the others were unable to.

Bianca later joins a Quest, and she dies halfway through the adventure. At the end of the book, Nico discovers that Bianca and himself are the daughter and son of Hades.

Later in the series, Bianca comes back as a spirit, through a sacrifice from Nico. She explains to Nico that her death wasn't Percy's fault and there was nothing he could have done to help. She also tells him he must forgive Percy, as holding grudges is the fatal flaw of a Hades child. This allows her brother to make amends with Percy and ensure he is on the gods' side for the war.

The Battle of the Labyrinth
Percy later finds out that Bianca was causing the dreams he had about Nico and the Ghost King Minos.

The Last Olympian
In The Last Olympian, she appears to her brother when he tries to summon their mother's spirit warning Nico not to summon her; explaining that she is the one ghost he is not allowed to summon and that she has been hidden by Hades due his grief over her death. Instead of summoning her Nico sees a memory from his early childhood where Maria was killed by Zeus in attempt to get at the children.

Personality
Bianca is quiet and shy, and loves her brother, but dislikes caring for him all the time, and was relieved to be able to be her own person when she joined the Hunters. She got along well with Percy, but he was angry with her when she joined the Hunters instead of coming to Camp, as this made him feel as if losing Annabeth had been for no reason at all. He later forgives her.

Bianca is somewhat lacking in common sense, as it was her own fault Talos attacked them, because she didn't listen to the warning of Aphrodite. She is willing to make up for her own mistakes though, and died as a result.

Her father Hades mentioned that Bianca would have made a better child of the prophecy then Nico.

Like her father, both Bianca and Nico have a habit of gesturing with their hands while talking and when they are on edge.

Physical description
Bianca has black silky hair, and dark black eyes that remind Percy of her father Hades. She has olive skin, freckles across her nose, and wears a floppy green hat that hides her face. She gains the silvery aura all Hunters have after she pledges herself to Artemis, and doesn't hide behind her cap anymore, and she pulls her hair back.
