Asuka Heart

Asuka Heart (飛鳥ハート, Asuka hāto) renowned by her moniker Jigoku shōjo (地獄少女, Hell Girl) is the daughter of Margin Heart and Yukidomari. After the death of all her family, and Ciel, she merged with her zanpakuto to force out all of her memories to ease the pain in her heart.

Appearance
Taking the appearance of a young teenage girl, Asuka possesses the average built and height of one. Her hair is long and black that shines whenever light passes through it. Her eyes are often compared to rubies because of the red glow it emits which could sometimes appear beautiful or scary. Her skin is white, literally white that the sight of her with all of her other physical traits make her seem like one of those ghost stories and gives the feeling of uneasiness. But one cannot deny her attractiveness, her face is young and innocent-like but there would always be something in her physical appearance that is quite alluring. She normally wears a black seifuku, or sailor uniform something her mom made for her but was later destroyed after her merging with her zanpakuto though she could be seen wearing similar clothes later on (due to her zanpakuto's ability and some unknown sentimental value that still lingers within her thoughts, the clothes manifest whenever she wills so). She could also be seen wearing a kimono that varies in design, it should be noted that the kimono is her zanpakuto's physical manifestation and a representation that Asuka merged with it.

Personality
Asuka, even before her amnesia, is a girl known to display little to no emotions at all. She is not likely to express what she feels and would often keep to herself. She has problems regarding how to show what she feels through words, thus would most likely keep quiet. Her perspective on things is then overlooked most of the time as she simply does not want to participate. However, her shy-like approach does not mean that she does not care. Asuka had shown several times that could take things on her own hands whenever she feels it is the right thing to do and would not think twice before having to stand up for the ones she cares for as she displays a rather different persona whenever protecting people she loves, having no fear to use words to show this.

Her personality also changes dramatically whenever Ciel is involved, she somehow gains a great amount of confidence and tends to exaggerate her actions. She'd outright tell you what she have in mind if ever you speak of her man and would not hesitate to use mockery and insults once you cross the line by bad-mouthing Ciel. She quickly changes from passive to agressive. This part of Asuka's personality is shown even while in her amnesiac state though in a much lesser degree as she could only remember Ciel slightly.

Whenever in a fight, Asuka maintains her quiet nature but acquires a deadly sadistic side that every Heart possesses. The lust to spill blood, a family trademark that Asuka inherited. She does not habitually grin while in the heat of battle like her father or grandfather but the level of her lust is just the same as the two or quite possibly be more. Her lust to fight manifest itself within Asuka as the unavoidable tremors only she could feel though she keeps this in check most of the time. At best, Asuka's becomes nigh unstoppable unless knocked-out or killed, a very heard feat for anyone to do.

Powers and Abilities
Immense Strength - Despite her apparent size and stature, Asuka's strength is to be considered "monstrous". This is shown when she single-handedly lifted a 4-story building to look for the toy she had grown fond with after finding it in the garbage. Her strength is known for being able to push back a horde of hollows and sucessfully crush them against a small hill without showing any significant effort.

Immense Speed - Before her ascent to what she is now, Asuka had already shown speed much faster than what her father, who is also known for possessing law-defying speed, is capable of. Now, being a essentiam inferno grantor, her maximum speed limit had increased to such ridiculous extent that catching up with her would now seem impossible for anyone below captain level.

Immense Spiritual Power - Even as an infant, Asuka had shown the great amount of spiritual energy that resides within her. At its lowest, it is comparable to a captain and at its prime, the level of reiatsu she emits is truly terrifying. Like a true demon, her mere presence brings darkness to even the brightest of places. Clouds form as the very earth shake. Ordinary humans suffocate with death occuring at a very high rate. It rivals that of his father's in terms of monstrosity and power. Even captain-level combatants find it hard to even stretch their muscles or move effectively in her presence. The weight and pressure her reiatsu brings is some ways unbearable to those who are unexperienced. Many had been crushed simply by trying to go near her. Her reiatsu is also corrupt and demonic in nature, bringing fear to even the most battle-hardened fighters. Unknowingly, Asuka is sometimes able to project bloody outcomes into her opponent's mind by being exposed to her monstrous reiatsu.

Keen Intellect - Although her overall experience is not that high, Asuka had shown to be very good at understanding concepts behind how things work. Her intellect allows her to grasp knowledge far beyond what her age should possess. Her curiousity another factor that helps her to gain information through various means. She gathers data in which becomes completely attached to her way of viewing things by unorthodox but nonetheless resourceful ways. The pace of her learning is in such a pace that complex physics is easily understood by her, even in the midst of battle.

Expert Stategist and Tactician - Unlike many of her predecessors, Asuka is not the type to simply rush in without a plan. Combined with her fast-paced learning and overall abilities, Asuka is one foe to look out for in terms of tactical warfare. Due to her wide-array of battle-ready abilities, Asuka is one to know what to do and is prepared for whatever it may be that could happen. Her unpredictable way of fighting makes her a truly fearsome foe. She often surprises her opponents with feats that sometimes just come out of the blue without warning. Even though her skill in strategizing and making tactics may not be as good as with others, she is still not to be underestimated in this area.

Essentiam Inferno Abilities
Having been merged with her zanpakuto, she gains a sudden burst of overwhelming powers that she once didn't have any access to. Essentiam Inferno is a type of parasitic substance that resides in hell, in which is the base of her zanpakuto's special abilities. The substance is that which drains one's soul bit by bit in exchange for greater power. Although this substance is still not truly understood, it is still a material that is sinister in nature and very dangerous to anyone.

Shape-shift and Body Manipulation - One of the essentiam's main ability is to take form of any material or substance that it wants to take. Through good imagination, Asuka is able to expand this ability to its highest and achieve the strongest of its potential. It enables her to manipulate her body at will, taking shape of anything she wishes. As her whole body is made of Essentiam Inferno, there is no limit to whatever object she wants to copy or gain attributes of. The body manipulation only takes an instant to materialize, thus making her transformations lightning fast to have her interact with her opponents in a much faster pace.

Regeneration - Having the essentiam compose mostly of her body, Asuka possesses the ability to regenerate from almost any wound. Limbs regrow at such speed that it happens almost instantaneously.
