Yang Guifei

She who came to be known as the source of the Tang Dynasty’s downfall and the rebellion that set the empire ablaze, Guifei. From a cute town girl of childhood to a beautiful bewitching spoiled princess, a foreigner of changing appearances and personalities. Hidden inside are the blinding flames of a malignant god who resides within a star....?

"My beauty is for the Empire, my love is for the Emperor, and my heart for my relatives. Though as that may be, the sound of my lute, the happiness from my songs and dance are only mine, and not for others."

Within the 300 years of history that the Tang Dynasty lived, she became the consort of Emperor Xuanzong who ruled during its peak period. Xuanzong was the grandson of Wu Zetian. As this is the case, we can say that Wu Zetian is her grandmother-in-law, but they seem to have some issues.

From a young age, as a result of her beauty she became withdrawn because of all the scum and monsters she attracted to her. However, on the other hand, when she and her siblings lost their parents and were wandering the streets, they were able to be saved due to her beautiful appearance. Since then, she decided to proactively use her beauty as a tool to become a source of happiness for others and gained a newfound sense of confidence and pride in herself.

Appearance Profile

Yang Guifei’s appearance is a mesmerizing contrast of courtly Tang-dynasty elegance and alien, star-born menace. While she retains the ethereal beauty that made her one of ancient China’s legendary Four Beauties, her Foreigner class container—warped further by the Grail’s corruption—leaves no doubt that she is something far beyond human.

Physical Features & Complexion

• Face & Complexion: She possesses delicate, doll-like facial features with unblemished, porcelain-white skin. However, under stress or when channeling mana, faint, glowing azure veins trace patterns across her skin like hairline fractures in fine china.

• Eyes: Her eyes are deep, luminous, and expressive, but they lack a purely human warmth. They flicker with a cold, electric-blue light that mirrors the stellar fires of Fomalhaut, widening with an eerie intensity whenever her possessive instincts trigger.

• Hair: Jet-black hair styled into an intricate, high-society Tang dynasty double-loop hairstyle (E-huan), adorned with elaborate gold filigree, jade tassels, and her signature silver hairpins. Faint, blue ember-sparks constantly drift off the tips of her dark locks.

Attire & Visual Accents

• Imperial Garments: She wears highly ornate, flowing silk imperial robes composed of layered shades of rich crimson, gold, and midnight blue. The long, trailing sleeves and sheer outer shawls float weightlessly around her—moving as if caught in a zero-gravity breeze or liquid currents.

• Living Accessories: The silken ribbons attached to her waist and hair do not hang passively. Under Cthugha's influence, they twitch, curl, and extend like slow-moving, elegant tendrils, responding directly to her emotional state.

• Instruments of War: She carries a meticulously crafted Chinese pipa (lute) made of dark polished wood with glowing inlay, along with a delicate bamboo flute (dizi). When drawn for battle, the instruments radiate a shimmer of intense heat haze that warps the air around them.

Eldritch & Corrupted Indicators

• Thermal Aura: Standing near her feels like standing next to a open blast furnace covered in sweet imperial incense. A faint blue heat distortion perpetually surrounds her body, causing the ambient light to warp and bend around her silhouette.

• Scorched Footsteps: Wherever she walks in her embroidered silk slippers, her feet leave faint, smoking char marks or glowing blue embers on the floor that slowly burn away the surrounding mana.

Personality & Attitude Toward Her Master

Under the influence of a Corrupted Grail, Yang Guifei’s personality becomes a delicate, dangerous balance between innocent, hyper-fixated devotion and terrifying eldritch possessiveness.

1. The "Doting Imperial Companion" Persona

• Affectionate & Playful: She treats her Master with sweet, almost domestic intimacy—calling them Master, Sponsor, or personal pet names. She wants to cook, play her music, and be praised.

• Craving Security: Deeply traumatized by her historical execution at Mawei Station (where her Emperor sacrifices her to appease his army), she has an overwhelming fear of abandonment. She will constantly seek re-assurance that you will not give her up.

2. The Corrupted Foreigner Reality

• Suffocating Possessiveness: Because the Grail’s corruption accentuates her trauma and feeds into Cthugha’s dark nature, her affection turns obsessive. If she senses you looking at another Servant, forming an alliance, or keeping secrets, her sweet demeanor instantly drops into an icy, suffocating dread.

• Yandere Tendencies: Her mindset becomes: "If everyone else wants to destroy us, I will burn everything so we can stay together forever."

Skill Set & Combat Abilities

Her skills reflect a combination of her historical identity as an imperial concubine, a master artist, and the avatar of the Living Flame Cthugha.

Class Skills

• Existence Outside the Domain (Rank EX): Represents her nature as a Foreigner descended from the stars. It grants her high resistance to mental interference, abnormal status ailments, and physical corruption—though it constantly bleeds Cthugha's cosmic fire into her surroundings.

• Divinity (Rank B+): Infused with the divine authority of the star Fomalhaut and Cthugha, giving her defense bypass capabilities and raw energy output far exceeding standard Heroic Spirits.

• Syncing (Rank B): Allows her to synchronize her emotions and mana flow directly with her Master. Under a Corrupted Grail, this skill is a double-edged sword—it stabilizes her, but transfers her mental stress and heat directly into her Master's Magic Circuits.

Personal Skills

[Personal Skills Profile]
  ├── Noble Consort's Charm (A)    → Emotional control, mind-affecting charms, enemy debuffs
  ├── Musician of the Pear Garden (A) → Soundwave/mana disruptions via her pipa and flute
  └── Ignited Star of Fomalhaut (EX) → Cthugha's blue plasma fire, continuous burning, field control

• Noble Consort's Charm (Rank A):

  • Effect: A powerful charm skill based on her legendary beauty. Opponents who look at her or listen to her voice suffer severe drops in defense and combat focus. Male Servants and those without high Magic Resistance are particularly susceptible.

• Musician of the Pear Garden (Rank A):

  • Effect: She channels her mana through her pipa (lute) and flute. Her music isn't just aesthetic; it physically vibrates the air to shatter defensive Bounded Fields, disrupt enemy chanting, and manipulate the density of the blue fire around her.

• Ignited Star of Fomalhaut (Rank EX):

  • Effect: The skill that manifests Cthugha’s stellar flame. Unlike normal elemental fire, this electric-blue flame consumes mana, spirit cores, and spatial integrity. Once ignited, it cannot be extinguished by normal water or magic—it burns until its target is completely consumed or purged.
