"Where are you staring with such a foolish expression? Are you...a pervert?" 
Raquel Alucard (ラケル＝アルカード) is a vampire, the 'daughter' of Clavis Alucard and the master of Naoto Kurogane. She is a straightforward young woman who seeks the Azure. Although she seldom shows it, Raquel is rebellious and has a kind heart, although she will often get confused at anything informal.
Raquel is one of the two main protagonists of BlazBlue: Bloodedge Experience - Part 1 and BlazBlue: Bloodedge Experience - Part 2 alongside Naoto. She appears as a non-playable character in BlazBlue: Central Fiction.
Pale, blonde, slim, and tall. Raquel has eyes that flicker between red and amber, and delicate features that reminds others of dolls. She is nearly always seen naked, or at the very least wearing her signature black mantle with numerous red crosses along it. In the rare instances that she does wear clothes, Raquel is seen wearing clothes given to her by Yuki Hayami, which consists of a plain white shirt, a red tie, and a black skirt with a black belt wrapped around it. In her uniform, Raquel also wears white socks with red stripes and ribbons that hold her hair in a ponytail. The way the ribbons are wrapped can lead some to describe her like a rabbit; even with her hair tied up, it still easily reaches the floor.
Shameless. Raquel is often seen parading around naked, feeling no need to wear clothes. She does not care much about what human society would think about her, and so often does as she pleases without thinking of the immediate consequences. This has gradually softened over time. Raquel is also rebellious, going directly against Clavis' wishes many times and has sought her freedom to become her own individual.
Initially, Raquel did not think much of humans thanks to Clavis' upbringing. She thought of them as being cowardly and would sacrifice anyone to save their own skin. Naoto has gradually helped her see humans in a different light. Raquel seems to have no problems using Slave Red to enforce her will on others.
Whenever she is around a female, Raquel has strong panic attacks; the more feminine the woman, the worse the panic attack. As she has spent more time with women, mainly Haruka Hayami, she has gradually managed to deal with the attacks. She does, however, still struggle with new people and very feminine women like Kiiro Hikagami.
Because of her education and little interaction with the real world, Raquel often has trouble understanding colloquiums and can get confused with anything remotely sexual, although she despises comments on her chest. She is pure in the sense that she does not quite understand romance or anything relate to it, but she longs for real familial bonds. In her spare time, she can be found reading books for more knowledge, although some of them contain questionable information (such as Definitive Edition! This Is the True Blood-Type Fortune-Telling Part 7).
Her relationship with Naoto is unique. Although she does not like to show it, she cares greatly about him, but their relationship is still that of master and servant. She does not care about seeing him naked, saying that he is no different than a dog. However, the two are still extremely close, even though she consistently embarrasses him.
Powers and Abilities
As a vampire, Raquel has some of their signature abilities. She can turn others into her kind through a single bite, has supernatural physical strength, and can use Slave Red, a powerful sorcery technique that allows someone to enforce their will on others. Raquel also has the ability to melt into the shadows of others, becoming intangible and uses it to rest. Her strength as a vampire is often demonstrated as she walks openly in the sunlight, something that not many of them can do. Raquel has a unique ability to sense the Azure, as well as its Remnants, in a fashion similar to a radar.
Raquel's Drive is Tempest, which is complete dominion over the wind. She can conjure strong gusts out of nowhere which can easily throw even the heaviest of opponents. Raquel will occasionally use this to fly great distances, and can even carry around 70kg with her while doing so. Raquel is also a practitioner of sorcery, using various circles to amplify her power, and in certain situations, she will cast protective sorcery to help her on the defensive.
Information is Raquel's strongest point, however, as her 'education' was streamed into her head from the Boundary. She has stated that she has "5,000,000,00 times more knowledge" that Naoto, although this was likely a demeaning brag. Raquel can also take the personal information of others by sucking their blood. She can share her life-force with others and construct fully functioning limbs out of her own blood.
However, Raquel has some weaknesses. She cannot fight against women because of her anxiety, and her Drive isn't combative by nature. Her confidence has also landed her in some trouble with underestimating opponents, and her knowledge only extends to formal subjects - she will be caught off guard by anything else.
