Bianca di Angelo was an Italian-born Greek @Demigod, a daughter of @Hades and @Maria di Angelo, and the older sister of @Nico di Angelo. She became a Hunter of Artemis after being saved by them. She later died (killed by one of Hephaestus' defective automatons, Talos) at the age of twelve and chose to be reborn after reaching @Elysium.

History

Early Life

Not much is known about Bianca's past. She was born in Venice, @Italy to Maria di Angelo and Hades in or around 1930 (Her brother, Nico was born 2 years later), before World War II, so Hades never broke the oath he took with his brothers to never have any more demigod children. She was raised in a Catholic household. At the age of 8, she visited @Diocletian's Palace with her mother and brother.

Maria di Angelo's Death

Bianca and Nico both moved to Washington, D.C. at some point. At the beginning of World War II, when Bianca and her brother were children, their mother, Maria, died when @Zeus struck the hotel they were staying in with lightning in an attempt to kill the siblings, to circumvent the Great Prophecy. However, they were protected by Hades as he erected an impenetrable wall of black energy to shield them from the @Master Bolt; however, Hades was not able to protect their mother in time. Afterward, a devastated Hades ordered the Fury @Alecto to take Nico and Bianca to the @Underworld and bathe them in the River Lethe, in order to wipe their memories.

Temporary Home

After her memory was erased, they went back to Washington D.C. and stayed in a Hotel/Casino for a couple of months, with a lawyer (Alecto in disguise) checking in on them every once in a while. Time in the @Lotus Hotel and Casino moves slower than time outside, so when Bianca and Nico thought they had spent a couple of months in the casino, the truth was that they actually spent about 70 years there. After all this time Alecto, disguised as another lawyer, came and drove the Di Angelos all the way to Maine, where they attended the military boarding school, @Westover Hall.

Modern Life

The siblings' school tuition at Westover was paid for by Hades using what Nico and Bianca thought to be a trust fund left to them by their parents. Bianca mentioned that the summer before she left Westover Hall (during the events of @Percy Jackson's first quest), she and Nico visited Washington D.C. once again, and were very surprised to see several subway stations that had not been there before; she later mentions that during their visit, several monsters (disguised as mortals) attempted to attack them in an alley. Nico also mentions seeing a bus driver with ram's horns (most likely a satyr in disguise), though Bianca had not believed him at the time.

Nico mentions that Bianca was the only one who always accepted him. This most likely implies that Bianca knew about her brother being homosexual before she died and chose rebirth.

The Quest

During a dance at Westover Hall, she and Nico stand in the corner and were kidnapped by Dr. Thorn. She is surprised to learn that the vice principal is a manticore and fears for herself and her brother. However, the siblings are saved by Percy Jackson, @Annabeth Chase, @Thalia Grace and @Grover Underwood - along with the intervention of @Artemis and the @Hunters of Artemis. After the fighting dies down, Dr. Thorn and escapes with Annabeth. Panicking, Bianca becomes to know what is going on and she and Nico are told that the gods and monsters from Greek mythology are real and that they siblings are the children of a god. Nico talks the news better than her. After calming down, Zoë Nightshade - the lieutenant of Artemis has her describe what she saw to the goddess and she is invited to join the hunt. Due to her lack of understanding, Percy is brought in to give a more detailed account. Artemis reveals the Great stirring has begun and again asks Bianca to join the hunt, she accepts and swears the oath.

The next day Artemis orders her twin brother Apollo to bring Percy, Nico, Grover, Thalia, and The Hunters to camp. @Apollo agrees and takes them to camp in his @Sun Chariot. Before boarding, she tells her brother about her joining the hunt. When the Hunters arrive at camp, with the daughter of Zeus driving and crashing into a canoe lake, they immediately head to @Artemis's Cabin (Cabin 8), ignoring Grover's help and not wanting to interact with any campers. After dinner, Chiron then announces that there will be a game of Capture the Flag, since this is a tradition for whenever the Hunters come to camp. The Hunters defeated the campers. Shortly after, the Oracle comes to give Zoë Nightshade a prophecy about a quest to save Artemis. There is then a meeting to determine who will go on the quest. Zoë does not want any male to accompany her on the quest, with an exception of the satyr Grover Underwood. The quest members are Zoë, Bianca, Phoebe, Thalia, and Grover. On the day to leave for the quest, Phoebe is covered in hives from a shirt the Stoll brothers tricked her into wearing, which was secretly covered in centaur blood. This was supposed to be revenge for what she did to the Stoll brothers during Capture the Flag. Without any time to waste, Bianca departs for the quest with just four people.

Without anybody knowing, Percy follows them on their quest, riding on his pegasus @Blackjack. Percy then spies on the enemies using the @Yankee Cap of Invisibility, which turns the wearer invisible. Percy then runs into Thalia, Grover, Zoë, and Bianca in the @Smithsonian, where they receive all the information. Shortly after, the Nemean Lion attacks. Bianca helps by climbing to higher ground and shooting arrows at the Lion.

Bianca's Timely Demise

While traveling through the desert, they cross through the @Junkyard of the Gods, which @Aphrodite had warned them not to take anything from. Bianca shows lots of fascination in everything in the Junkyard, Especially a Hunter's bow that turns into a crescent shaped hair clip. When the five are about to leave, one of @Hephaestus' automatons, Talos, attacks. Percy and Bianca hide from Talos together, where Percy accuses Bianca of taking the Hunters Bow. Bianca then informs Percy that she had not taken the Hunters Bow, but a Mythomagic figurine for her younger brother, Nico, because he had collected many and that figurine was the only one missing in his collection. Percy and Bianca then came up with a very dangerous and deadly plan to defeat Talos. Percy says that he'll do it, but Bianca doesn't allow him, because she believes that she should face Talos since she was the one who took the figurine. Before going, Bianca gives Percy the figurine and tells him to give it to Nico if anything happens. Bianca starts out with the plan working well, but then Talos crushes Bianca as Talos falls. Zoë, Percy, Thalia, and Grover start desperately looking for Bianca with no luck. Grover offers to stay a night to try to find her tomorrow, but the others say it is no use, because it was prophesied that a quest member would be lost in 'The land without rain', which is the desert. Percy felt responsible for Bianca's death, as he thought that it should have been him.

After returning to Camp, Percy was forced to inform Nico of his sister's death. A distraught Nico blamed Percy for the loss of Bianca whom Nico could sense was currently standing in the @Fields of Asphodel being judged. Four Skeleton warriors appear out of nowhere. Nico screams 'Go Away', opening a fissure in the ground which the Skeleton warriors fell through. After this, Percy found the figurine and realized that Nico was a son of Hades. Based on Bianca's story, Percy also figures out that Hades did not break the Pact of the Big Three but instead Nico and Bianca had been kept in the Lotus Casino for decades.

Legacy

As Nico's Spirit Guide

Percy later finds out that Bianca is sending him Iris-messages so he could see what Nico and the ghost Minos were up to after the son of Hades had fled Camp Half-Blood.

Later, the daughter of Hades comes back as a ghost, through a ritual performed by Nico who was persuaded by King @Minos. She explains to Nico that her death wasn't Percy's fault and there was nothing he could have done to help, as she made the fatal decision herself. She also tells him he must forgive Percy, as holding grudges is the fatal flaw for children of Hades. This allows her brother to make amends with the son of @Poseidon, and ensure he is on the gods' side for the war.

A year later, Bianca appears to Nico when he tries to summon their mother's spirit. She warns Nico not to summon their mother; explaining that she is the one ghost he is not allowed to summon and that she has been hidden by @Hades due to his grief over her death. Instead of summoning her, Nico sees a memory from his early childhood, where Maria was killed by Zeus in an attempt to kill the children.

Moving On

Nico mentioned to his half-sister @Hazel Levesque that Bianca chose to be reborn, presumably trying for three rebirths and three selections for Elysium, so that she could earn entry into the @Isles of the Blest. Nico was devastated by this, as he was planning to sneak her out of the @Underworld, since no one would have noticed due to Death having been captured. So, instead of sneaking Bianca out, he brought Hazel with him, for a second chance at life.

During the Quest to Rescue Iapetus, Maria and Bianca appear to Nico in a dream, explaining that although they have both moved on, they were granted one last visit with him by Hades who proves that he is real. Hades reveals that he's the one who sent Nico after Iapetus, causing Maria to frown when Nico mentions that Hades had once told him that he was annoyed that Nico wasn't as good of a demigod as Bianca. On Maria's prompting, Hades explains that @Percy Jackson had changed a lot of things for the gods, making them rethink their priorities, standards and behaviors, causing Hades to have second thoughts after he sent Nico the prophecy and realized that it put Will Solace in danger too. However, Nico had made Hades incredibly proud so he decided to break the rules and show him how proud he is by allowing his son to see Maria and Bianca. Nico's family express their pride in him and tell Nico to go and be happy with Will for himself. Nico is finally able to let his mother and sister go, noting that they seem completely at peace as they vanish.
