Shadow Slayer

Main article: Mysterious Archer § Appearance

The Slayer is described as a beautiful woman with a slender and graceful figure, exuding extreme agility and strength. Her poise is unmistakably that of a warrior, with a hint of pride in the set of her bare shoulders. Her luscious ebony hair is gathered into a long braid, and her lean muscles appear sculpted by an obsessed artist. However, her entire body is entirely black, as if cast from ink, with not a hint of color visible, reinforcing her nature as a shadow.^[4]

She wears very light armor, consisting of a pteruges skirt, a chest guard, a single bracer, and greaves protecting her shins—armor clearly designed for an archer rather than a melee combatant. The light ensemble enhances her graceful appearance, making her resemble a dancer more than a fighter.^[4]

Her face is hidden behind a veil, but her sharp, elegant features are still vaguely discernible—high cheekbones, a sharp nose, and most strikingly, lifeless black eyes that stare at him with no emotion.^[4]

The Slayer is a powerful and rebellious Shadow, distinct from Sunny's other Shadows due to her intense resistance to control. Unlike his other loyal Shadows, she does not obey his commands unquestioningly. Instead, she fights against his influence, displaying an unnerving willpower that allows her to resist direct orders, even though doing so weakens her. Described as having an infinitely cold killing intent, she does not engage in conversation and instead responds to Sunny with murderous glances.^[9]

As a Shadow Creature, Slayer did not wield a true Aspect or Flaw but retained powers derived from Orphne's Aspect.^[12]

• First Ability: allowed her to understand and communicate with all manner of beasts and living creatures, including comprehension of human languages.^[12]
• Second Ability: greatly enhanced all her senses, giving her eerie accuracy when shooting a bow over vast distances, great at laying ambushes, and almost impossible to catch unaware.^[12]
• Third Ability: combat-related Ability that let her imbue attacks with soul essence, making them more potent — a mystical power somewhat reminiscent of Samara's, though with a different effect.^[12]
• Fourth Ability: corresponding to Orphne's Transcendent one, allowed her to take the shape of beasts she had encountered through sight, sound, smell, touch, or by tasting their flesh and blood. She was a shapeshifter, capable of assuming various forms, such as a hawk or a fearsome black leopard strong enough to kill one of the Sacred Spirits of Heart God's forest. The runes described "beasts" vaguely as "bestial things", which left questions about the full scope of her transformations—whether she could take the forms of Nightmare Creatures, mythical beasts like dragons, or even bestial forms of human Saints.^[13]
• Fifth Ability: tied to the very essence of Supremacy itself, the Will. This Ability was an extension of her other powers and allowed her to clearly sense and understand the Will of other beings, as well as communicate her own more effectively. For instance, she could imbue her weapons directly with her Will, making them deadlier.^[13]

She wears minimal armor, she lacks the need for weapons, as her entire body is a weapon, capable of easily tearing Sunny apart.^[4]

Slayer's swordsmanship is marked by unwavering precision and brutal efficiency. She moves with complete sincerity and purpose, with no hesitation or wasted motion, translating her intent directly into action. Her hearing is incredibly sharp—capable of detecting even a needle dropping kilometers away—allowing her to remain hyper-aware in the chaos of battle.^[14]

Slayer wields the Will with exceptional finesse. Because her mind and intent are completely aligned, there is no friction between thought and action. This grants her remarkable efficiency and control, enabling her to achieve more with less effort.^[14]

Unlike most beings, Slayer possesses single-minded certainty and emotional purity in combat. This state of certainty enhances her effectiveness and makes her a perfect killing instrument.^[14]

The core of the Slayer is unique compared to Sunny's other Shadows. While most of his Shadows possess dark embers instead of Shadow Cores, the Slayer is different. She originally had a radiant Soul Core despite being a shadow, making her distinct from the others. However, after becoming one of Sunny's Shadows, her radiant soul core was gone, replaced instead by a radiant shard. This shard exists in a peculiar state—not quite Transcendent, but also not quite Supreme, as if it is lacking something.^[4]

• It is explicitly stated that the shadow is not one of the Nine, but rather a shadow of an original member. Unlike its original form, the shadow is described as feral and mindless, acting on base instincts without rational thought or higher purpose. The shadow's existence is viewed as an insult to the memory of the original being.^[16]
• This shadow was able to hide the scent of it's soul from predators of Shadow Realm.^[17]
• Slayer was a unique being — a Shadow with silver light of pure soul essence. She existed between two Ranks: beyond Transcendent but not quite Supreme (Debut). Although she fought under Sunny's banner, she felt no loyalty toward him, acting independently.^[5]
• In Chapter 2316, it was shown that Slayer can write (using rune).
• Slayer's Transformation Ability allowed her to assume the forms of all beasts she had killed.^[18]
  • In Chapter 2848, Slayer took the form of an enormous black tiger.
  • In Chapter 2910, Slayer took the form of a Dragon, a great obsidian dragon that can breath out a torrent of lightless black flame from her maw.
• The destruction of one of Sunny's Shadow Cores in Chapter 3110, reduced him from a Titan to a Terror and left Slayer without a Shadow Core to inhabit, preventing her from being dismissed or healed by the dark flames of his soul.^[19]
