Delta

Delta (デルタ) (Δέλτα), formerly known as Sarah (サラ), is the fourth member of Shadow Garden, being one of the "Seven Shadows". As a Beastkin Wolf, she acknowledges only strength, swearing loyalty to the Shadow in awe of his overwhelming power.

Appearance
Delta is a beautiful teenager with long black hair and with large dog ear sporting on top of her head. She sports purple eyes. Her body is a slender build with an ample bosom.

Her attire comprises of the customary slime bodysuit with black and bronze coloring.

Personality
In accordance with the common personality of any Beastkin, Delta is often described as a musclehead and depicted as excitable and immature, akin to a child. She also refers to herself in third person. Delta deeply loves her master, even going as far to hug him in every occasion they meet. She also doesn't mind the idea of mating with him and sharing him with her fellow Shadow Garden members. She and Gamma have had a rivalry ever since they were children, but they nonetheless care for one another.

As a member of Shadow Garden, Delta loves fighting. She is shown to be merciless and sadistic towards enemies, leaving none of them alive. This makes her dangerous, as she will go overboard in brutality and even unnerve her master and her comrades. This is a trait of Beastkin, who will follow the strongest life form, regarding them as their leader. Hence, she had no qualms killing her brother, Olé whom she regarded as weak.

However, it's implied Delta does not totally believe in all of the Beastkin customs, and deeply hates her pack for exiling her.

Powers & Abilities
Delta is the third-strongest member of Shadow Garden, surpassed only by the Shadow and Alpha. Also, her tracking skills are second-to-none. However, she is utterly lacking in any other talents or skills, making her only useful for search-and-destroy missions.

Physical Prowess
In terms of raw destructive power, Delta is second only to the Shadow himself, with the only other person known to have defeated her being Alpha. As a Beastkin, she possesses superhuman strength and speed, further augmented by her training since youth, which makes her a highly-effective killer. In a testament to her strength, she killed Juggernaut, one of the Lawless City's three monarchs, with ease.

Due to being the dog sub-species, Delta also has excellent tracking skills, which the Shadow notes surpass even his own. Her sense of smell is so good that she can easily see through her master's disguises, even when he takes precautions by masking his scent.

Beastkin Senses
Being a Beastkin belonging to the wolves family, Delta has superior sharpness in her 5 senses, especially in smell, sight, and hearing, which allows her to track, see, hunt, and identify prey, even if they are trying to mask their smell, appearance, or other characteristics. Even the Shadow confessed he could never beat Delta in that area, and when he disguised himself as "John Smith" and faced her, it didn't work because Delta recognized him at once even through an attempt to mask his scent.

Combatant
Delta's hand-to-hand combat style is very simple, yet savage and brutal. Like any member of her race, she uses her claws and fangs to attack like a full-fledged wolf. She has also allegedly been trained in other skills and fighting styles, though it is likely that she does not need them.

Swordsmanship
Alexia Midgar described Delta's fencing style as "raw violence". As a Beastkin, she does not require more effort than simply swinging her sword around, more than making up for the fact that her technique is on the level of an average magic knight. Her strength allows her to easily slice an entire building in half.

In the game, she uses large gauntlets with claws.

Hunter's Frenzy
When there are enemies to hunt, especially against strong and/or numerous enemies, Delta goes into a frenzy which causes her to become much more aggressive and fierce. Delta likely exhibits a stronger and more brutal form of this ability than the rest of her family, since she had to learn to hunt by herself following the death of her mother at a very young age.

It is impossible to stop or calm her down in this state, with Alpha having to resort to intimidation to make her snap out of it. When Delta confronted Nelson inside the Sanctuary, she got so excited that she annihilated everything despite Nelson unleashing his full magical power, not caring very much about the depletion of her slime suit, except the parts covering her private parts.

Magic
Delta does not seem to be capable of casting any spells aside from simple self-strengthening through mana control, possibly due to a lack of intelligence. However, she has taken this one spell she has to ridiculous levels, boasting superhuman strength that is surpassed only by the Shadow. She is also able to manipulate her custom Slime Bodysuit through mana.

Iron Slab
Delta can unleash her ridiculous magical power to manifest a huge sword of slime, which kills many multiple powerful enemies simultaneously. But in exchange, almost all of her slime suit temporarily disappears (leaving only the private parts covered), having been redirected into the giant sword.

During her battle against Nelson inside the Sanctuary, Delta used this technique to quickly kill several hundreds of clones that Nelson had created to kill her and Alpha.
