BlazBlue: Phase 0
Rachel Alucard (レイチェル＝アルカード) is a vampire, former Onlooker, and head of the Alucard Clan of vampires. She is the daughter of Clavis Alucard, and watches over the world from the Alucard Castle alongside her butler Valkenhayn R. Hellsing. Rachel wields the Sankishin: Tsukuyomi Unit, and has no life-force value. She is constantly followed by her familiars - Nago and Gii.
She is one of the original twelve characters who debuted in BlazBlue: Calamity Trigger.
Rachel is a pale skinned girl with red eyes, and long blonde hair tied into twin tails with black ribbons, which resemble rabbit ears when done up. Despite looking like a young girl, due to being a vampire, Rachel is much older than she appears.
She wears a black knee-length gothic-themed dress with bell sleeves and a matching skirt. Over this she wears a shawl in the same color as her dress. A large red ribbon sits in the front of the dress with white frills under both the skirt and the sleeves. On top of the skirt are large red wings which can extend and contract according to Rachel's will. Underneath the dress, Rachel wears a sleeveless white ruffled shirt, a matching set of white bloomers and a pair of large, black, knee high, heel-less platform boots with red laces. The dress has a prominent cross motif with red crosses with a white outline appearing on several parts, specifically adorning the hem of the sleeves, the front of the skirt and on the shawl.
During the time of the Dark War, Rachel looked physically younger, closer in appearance to a six year old child. Her outfit was similar to that of her modern day self, with the exception of her dress having a large red cross on the front of her dress and instead wearing white socks and black shoes.
When using the Tsukuyomi Unit, her eyes take on a glowing amber color.
Refined, intelligent, and quiet yet arrogant, domineering, and self-centered, she rarely travels without Gii and Nago to accompany her. She treats them roughly; especially Gii, who always seems to be on the brink of death.
Contrary to her elegant and graceful appearance, Rachel is often overbearing and rude - delivering rapid, yet complex insults. She is righteously proud at times, boasting of her formidable power, and is known to bully Gii relentlessly, using him as a conductor for her infrequent bursts of rage. She enjoys teasing Ragna the Bloodedge and Hakumen, but is known to greatly respect the both of them. Additionally, she is heavily implied to be in love with Ragna.
Despite these characteristics, Rachel is undeniably wise, having knowledge and wisdom that surpasses most of the cast. She put her life in great danger to ensure that the timeloops would be broken and that Doomsday would be stopped. The people she treats with respect are often the ones who have earned it, such as Celica A. Mercury, Valkenhayn, Jubei, Tsubaki Yayoi, and eventually, Noel Vermillion. Although she may come off as domineering at times, Rachel cares far more greatly for the world and its people than she will let anyone know.
Even though she is a vampire, Rachel detests partaking in the consumption of blood, and will only do so if absolutely necessary. However, she does enjoy drinking tea and sitting her rose-filled garden with Nago, Gii, and Valkenhayn as company.
Powers & Techniques
As a vampire, Rachel possesses some of their signature abilities, such as being able to regenerate most wounds inflicted upon her and the ability to turn humans into her kind. Her Drive is Silpheed, which allows her complete control of the wind, being able to conjure slight breezes to deadly storms and whirlwinds. Her Drive is also used to help make her fly through the air. Her Drive is further amplified by both her mastery over sorcery and magic, which she often uses to summons bolts of lightning or teleport, on which there seemed to be little limit on how many she could transfer at one point. Additionally, Rachel possesses the ability Slave Red, which lets her take control of someone's mind with a look, giving them one order they cannot refuse. However, this ability has limits, as it was unable to affect Amane Nishiki.
Inside her body lies one of the three Sankishin, Tsukuyomi, which forms an absolute defence that is impenetrable from even the Boundary and Take-Mikazuchi. Instead of conventional weapons, Rachel uses Nago and Gii with their shape-shifting powers to help her fight, and she rarely lets herself take any direct damage.
Rachel, however, sacrificed a lot of her power once she gave up her position of Amatsumugi and Onlooker. Her sorcery power deteriorated to the point where she could barely teleport herself.
Head of the Vampire clan, 'Alucard.'
At one time she oversaw the Boundary with the Takamagahara System. She houses one of the Sankishin, the Tsukuyomi Unit, within her, and is an observer that has lived for millennia.
She knew of Ragna from when he was young, and presented him with the opportunity to wield the Azure Grimoire. She is also the one who gave Jin the Susano'o Unit.
She is refined and wise, and carries herself with an aura of elegance. But contrary to her appearance, she's quite free spirited, arrogant, and domineering at times. It is not uncommon to see her vilify anything that does not suit her tastes. She seldom lifts a finger to do anything, and relies on her familiars, Nago and Gii, to do her bidding.
While being a key player in our world, she is forbidden to intervene in its course of events. Thus, it has been her fate to silently observe history repeat itself over and over. But when Noel triggered change to occur once more in the world, Rachel devises a plan to take down her arch nemesis, Terumi, once and for all. She rescues Hakumen, and keep him under her domain.
Rachel is no stranger to the highest ranking member of the NOL, the Imperator. To put an end to the Imperator's scheme, she walks on stage, going from Observer to actor.
As one of the Chrono Phantasma, Rachel orders Tsubaki to use the Immortal Breaker ot destroy her, should Ragna died without being defeated by Jin or Tsubaki. That it was the only way for evil to be eradicated from this world forever.
It is still not known what she meant...' 
Variable Heart Glossary
When asking who is the strongest vampire in this world, it would be the “Crimson Vampire”. Or that is what the note that professor Kokonoe wrote said that I saw before.
If I remember the note, she lives in an old castle with her familiars. She has a beautiful appearance and a sadistic personality. She is the Onlooker of the world.
… I wonder if such an existence really exists. - Kajun Faycott
