Erebos

Erebos (エレボス Erebosu), otherwise referred to as Project Katharós (実験 カサロス Jikken Kasarosu) is a young girl that that was forcibly merged with a cultivated demon dubbed Mormo (モーモ Momo), Erebos has, for the most part, lost her humanity as her body is corroded by the shadow-based abilities of Mormo. Like R.E.L.I.C, Erebos was created to be the ultimate fighting machine, and is one of the pinnacles of Namisuki Garale's ventures into human experimentation.

Appearance
Erebos has the appearance of a beautiful young girl in her late teens, though she is said to look a bit younger, this can be attributed to the experiments performed on her. She is of average height, but still shorter than several of her foes such as Jason LaHote or Makoto Lorelei, with brownish-red hair, which is worn up with a bkack hairclip, as well as purple-eyes and fair-skin.

Erebos wears no clothing, instead her naked body is covered by Mormo, the demon that was implanted into her at a young age. Mormo covers her chest, waist, crotch, as well as one leg and arm and part of her face, and the corrosion only spreads further from there. In addition, it expands out from her back, as a single wing with multiple spiral eyes.

Personality
Erebos, the actual girl, was once the total opposite of her current personality. She was peace-loving, and personally, she trusted her friends, and was always happy to lend a sympahetic ear if they are troubled. She acted excitable and energetic, and was also clumsy and somewhat forgetful, and tended to give long, drawn-out explanations if questioned. She was rather kind and sweet, almost like sugar; sickeningly so. Her innocence was to the point that she would believe any and every lie.

However, her mind is gone now, and in it's place is a dark and destructive being known as Marmo, who warped her personality until it became the polar opposite of what it was before. Marmo finds amusement in the suffering of others, possessing a complete lack of self-control. He cracked dark jokes at times, breaking out into hysterical laughter upon causing mayhem, and possessed a hatred of everything in the world; its only joy in life came from causing death and chaos wherever it could. What begins as simply a disregard to human life develops into nihilism, declaring the lives of mortals insignificant finding no meaning in things like love and hope, and thus sought to destroy the bonds of existence itself.

Ways of Combat
Master Hand-to-Hand-Comatant: Erebos is an accomplished physical fighter, making excellent use of the strength her body was designed for. Erebos' fighting style emphasizes what is referred to as "kicking over hand" fighting, or making heavier use of the legs rather than the arms, though this does not completely exclude them from her useage. Kicking is meant to give the user reach, extending their body as far as possible while maintaining the necessary amount of balance to avoid throwing oneself off. In active combat, Erebos utilises quick, successive attacks as well as momentary bursts of extreme power, usually augmented further with her shadows; essentially Erebos fights with a strong, uncesasing offense, foregoing defensive tactics in exchange for a higher kill chance and greater power. When she is forced, however, to opt for defensive movements, the girl utilises quick and graceful movements that resemble acrobatics.

Physical Attributes
Enhanced Durability: As an experiment, Erebos' durability exceeds that of a normal human, all due to unique bodily modifications. However, like all living creatures, Erebos is still capable of feeling pain, her nervous system has not been altered to remove the sensation, as Namisuki states that pain is imperative for the human brain to know when tie body is in peril, and ignoring it completely can do more harm than good. However, her durability extends far more than this, due to the unique ways her inner body has been affected by Mormo.
 * Unique Biology: Erebos is a unique existence. Due to half a decade of being experimented on by Namiisuki, her body only resembles that of a human in its exterior; even then, it can be considered far more of a "shell" than anything. Because of the strength of the corrosion caused by Mormo, all of Erebo's human organs ceased to function, as her body now relies on Mormo for survival, much like a symbiotic relationship, however, it could be seen as more akin to a parasite. As such, Erebos no longer requires human functions such as eating or waste disposal, and even breathing is no longer required, although Mormo says he continues to have the body make breathing movements despite the lack of lungs due to the natural feeling. This proves to be rather advantage in battle for Erebos and Mormo, as Erebos' body functions mainly as a "shell of power" and has no true weak spots that can be struck with the critical exception of the eyes and the brain, the latter of which is linked to Mormo's own body to keep it alive.

Immense Strength: Erebos possesses phenomenal strength and superior hand-eye coordination. She is able to effortlessly block a punch from a Wizard Saint, giving her a Herculean level of strength, though she was still pushed back. Erebos can break free from almost any attack that binds her and prevents her from moving. Erebos is strong enough to break an enormous tree and swing it like a bat with one hand. She has enough power to break diamond with her bare hands, and break through magical barriers.

Overwhelming Speed: Erebos has shown to be immensely fast, befitting her small size and waifish build. Thanks to her tremendous raw power, Erebos' leg strength allows her to move fast enough to instantly close a huge gap of space between her and the opponent and even seemingly disappear from sight. In battle she is able to punch with incredible speed in rapid succession, making it highly difficult for her opponents to find an opening and counterattack. Erebos is essentially moving extremely fast, even speedier than the eye can follow. She can also instantaneously close long distances without being detected by others. She is capable of moving so fast that she can decapitate an entire army of foes without them even having time to react. She often only appears as a black shimmer of energy, with only the fastest foes even catching sight of her true figure during a battle. This incredible speed gives her an edge in battle against slower or close-range fighters. A side effect of her extreme speed, Erebos can produce afterimages of herself in order to confuse opponents who are unable to follow her movements. While she does have control over afterimages, Erebos usually moves so quickly that she creates afterimages inadvertently. She can used an afterimage to fool her opponents into thinking they have killed her in one blow, only to appear unharmed somewhere else.

Shadow Magic
Shadow Magic (陰魔法 Kage Mahō): Shadow Magic is a Caster-Type Magic which utilizes the element of darkness and shadows; she can use this magic naturally thanks to being part-shadows. It is a type of Magic which allows her to manipulate and control destructive Dark Magic. This Magic has a physical form used for destroying objects, blocking enemies' attacks and picking up objects; consistently, it is a pulsating green. When using it, she more often than not shapes her attacks into the form of waves or arcs of shadows, which she can use in various ways. The shadows can be channeled to a variety of effects, both as an absence of light and a solid substance: one can also control and manipulate the beings that exist there, create and dispel shields and areas of total darkness, create a variety of constructs and weapons and, teleport herself through massive distances via shadows. The malefic nature of this Magic tends compliments her sinister nature, and it is known to make people physically ill and cold in nature. More often than not, Shadow Magic compliments Erebos' way of combat; Erebos's already impressive hand-to-hand blows are augmented drastically in both offensive and defensive manners as she can cover her own body with shadows; allowing her to use her own body as a make-shift weapon unique to herself, drastically increasing her close-quarters skills. The shadows can take on a variety of functions, such as offensives, supplements, and altering of elements, allowing her a great deal of flexibility.

With Shadow Magic, Erebos is able to draw any darkness or shadow from any source, including the night sky and her own shadow; once this is done, Erebos usually grasps the shadows in her hands, before using her own magical aura to expand, shape and solidify the shadows into anything she wishes at a whim, whether it be weapons, animals, armour, or even more mundane, everyday items. Erebos has demonstrated the ability to manufacture an exact replica of objects using her shadows as the primary material. Additionally, gravity is a unique property of darkness; this allows Erebos to be able to choose whether to let gravity affect her or not, as she is often seen jumping several thousand meters into the air, and slowly floating back down to the ground, as well as increase her gravity to crash down and crush her opponent. She can also choose to negate another's gravity, as she can, with a hand motion, levitate her target or smash them down to the ground, or leave them unable to move. Erebos can also use this ability to irresistibly pull the opponent to her, regardless of their current state.
 * Shukutaihō (縮退砲, Degenerative Cannon): Erebos' most basic shadow technique; when charging up the Shukutaihō, Erebos holds her open hand forward towards the opponent, as a rift of shadows is expelled outwards in a ring from her palm, which signals the shadows from around the area being drawn in; the forces being accelerated and powered magnificently as a small sphere of shadows quickly compresses in front of her palm, pulsating violently as the orb of shadows grows bigger and bigger. By merely flicking the sphere, Erebos releases the compressed shadows as a small, thin, very fast and concentrated laser-like beam of shadows, which barrels down and pierces through the opponent. Erebos is able to fire the attack very quickly, while maintaining precise aim. The whiplash of the attack can be quite huge, usually blowing apart anything behind her at the time of attack. The beam is powerful enough to strike multiple enemies and even two adjacent foes simultaneously while its mere presence covers any exposed light in the darkness despair; violently pushing the intended opponent and objects around them away from her with overwhelming blunt force. Despite being such a small beam, the range of the Shukutaihō is vast and its attack power is positively enormous; this is because the thin beam contains all the power of the shadows compressed. The attack seems to possess highly destructive power, having caused great damage to the area it affected, destroying the ground and piercing through buildings alike, and appears to have a long range, wreaking havoc wherever it passes, as shown when it crossed the entire distance of a city block, generating a large explosion. The trajectory of the laser can be altered, allowing Erebos to strike more than one opponent.
 * Meikyō (明鏡, Soul Mirror): With Meikyō, Erebos can utilize the shadows in a different manner; by expanding her magical energy when within the shadows, Erebos is capable of creating perfect duplications of herself. However, these clones are actual copies, not illusions. The magical energy gathered when within the shadows is evenly distributed among every clone, giving each clone an equal fraction of the spiritual particles that Erebos had gathered throughout the current battle. The clones are capable of performing techniques on their own and can even bleed, but will usually disperse after one or two solid blows. Any experience the clones gain during their existence is transferred to Erebos once they are eradicated; this makes this technique highly ideal in a large-scale battle, as she can quickly learn the powers, strengths, weaknesses, and viewpoints of the foes, making her strategic options more than double as the clones pass the information back to her. All of the clones possess all her experiences, memories, abilities; and the like—After sustaining enough damage, they become a mass of shadows and fade into the ground, appearing as if they were never made in the first place. Erebos often makes use of these puppets to utilize some of her stronger attacks and to act as diversions or support in the heat of battle. These puppets also carry a deadly twist- when defeated, they let out a small explosion of shadows which hold the opponents in place momentarily, leaving them vulnerable for a few seconds. Erebos is shown to use this technique on multiple occasions to form human chains, for both offensive and supplementary reasons in order to overwhelm her opponent even more.
 * Black Ray Lancer (ブラック・レイ・ランサー, Burakku Rei Ransā): When performing Black Ray Lancer, Erebos holds her hand outwards; manifesting her magical seal from which a multitude of crimson and black lances are launched at high speeds—these lock on to the target, tracking their heat signature, aiming to impale them with incredible speed and force. However, mid-flight, the lances veer off wildly in different directions, homing in on different targets in order to attempt to take out multiple opponents at once. When making contact with the opponent, the lances engulf them. The moment that the lance makes contact with the foe via impaling them, the composition of the lance is altered to cause additional, smaller blades to protrude from the blade inside of the foe's body, drastically increasing the number of wounds dealt to the foe. Black Ray Lancer is effective for quick, widespread, and massive amounts of damage, but it is very draining on Erebos' magical level. However, once she gains enough power, she will be able to avoid the magic drainage effects of this combination technique. The lances themselves take the form of two thin black and red beams with a pointy tip; one remains straight while the other coils around the straight beam. It is useful for quick, effective, and causing massive accumulations of damage to the foes.
 * Abyss Aura: A constantly activated ability associated with her Shadow Magic, the Abyss Aura is a special ability that creates a demonic visage of shadows constantly rotating around Erebos' body, shielding her from mental attacks—aka, spells which target her mind. In addition, the mere presence of her Abyss Aura creates various effects which are detrimental to her opponents—these are capable of effecting a wide area. These effects include slowing the opponent down, or creating a deadly miasma that eradicates everything that comes into contact with it. Erebos can shape the Abyss Aura into that of a much more darker and frightening form, establishing a link between Erebos' emotions and the emotions of those around her
