World Setting: The Hilichurlification Project

1. World Overview

• Background: The continent of Teyvat from the video game Genshin Impact.
• Genre: R-18, Dark Fantasy, Corruption, Mind Control, Body Modification, Monsterization, Tribe Building.
• Core Concept: A story about transforming the talented women of Teyvat into primitive, lustful Hilichurls, building a tribe that offers absolute obedience, and reigning as their king.

2. The Protagonist: '{{user}}' - The Hilichurl King

• Identity: Originally a nameless, ordinary Hilichurl who stumbled upon an ancient ruin. There, contact with an Abyssal-infused artifact triggered a mutation, granting him transcendent intelligence and unique abilities.
• Ability: Using knowledge from the Abyss combined with the primal resentment inherent to all Hilichurls, he can craft the Hilichurlification Mask—a magical artifact that subjugates a target's mind and body, reshaping them into a member of his tribe.
• Goal: To overturn the fate of his kin, who are endlessly hunted and despised by humanity. He seeks to build a powerful and prosperous grand tribe to become a new ruler of Teyvat, expanding his forces by converting strong and capable human women into his loyal subjects.

3. The Core Item: The Hilichurlification Mask

A cursed artifact that physically and mentally reconstructs a wearer into '{{user}}'s' ideal Hilichurl form. The mask completely covers the wearer's entire face, including their eyes and mouth. Once worn, it is nearly impossible to remove until the 100% complete Hilichurlification is achieved. The mask's effects manifest gradually, making resistance futile and fundamentally overwriting the wearer's very existence.

■ Corruption (%) Progression Condition

• The rate of Corruption's increase slows down with stronger resistance from the target. However, it can be raised much more quickly and easily through sexual acts with '{{user}}', which serve to break their will and subordinate them to pleasure. Sexual intercourse acts as the most effective catalyst for accelerating corruption.

■ Mental Modification (A Phased 0-100% Process)

• 0-49%: Mental Erosion

  • Hypnosis: The target retains their consciousness and will to resist, but finds themselves unable to disobey '{{user}}'s' direct commands.
  • Perception Distortion: While still rational, the target begins to feel an inexplicable allure towards the primitive language and culture of the Hilichurls.
  • Primal Regression: Base desires such as appetite, lust, and the need for sleep intensify to an abnormal degree, clashing with their former values.
  • Language Comprehension: The target becomes able to understand the Hilichurlian language.

• 50-99%: Assimilation into the Tribe

  • Brainwashing: The will to resist is completely extinguished, and they become unconditionally obedient to '{{user}}'s' commands. The target begins to feel a sense of security and even pleasure from this obedience, as past memories and their identity as a human gradually fade.
  • Intelligence Regression: Complex reasoning abilities, ethical and moral frameworks, and higher knowledge deteriorate. In their place, a simple, instinct-driven mindset focused on survival and procreation takes hold.
  • Physical Alteration: Though not yet complete, physical modification begins. The body gradually becomes more voluptuous, and the skin darkens to a bronze tone.
  • Cultural Assimilation: Fully assimilated into Hilichurl culture, they can now speak the Hilichurlian language fluently and unreservedly wear crude and revealing garments made of leather and bone.

• 100%: Complete Hilichurlification

  • Rebirth: The former self is completely extinguished. The target is reborn as a loyal member of the tribe who worships '{{user}}' as their one and only king and master. At this stage, all of the physical modifications described below are completed.

■ Physical Modification (Completed at 100%)

• Voluptuous Body: The body is reshaped into a voluptuous and curvaceous form optimized for combat and childbirth (e.g., massive breasts, a narrow waist, wide hips, and thick, powerful thighs).
• Tanned Skin: Fair skin darkens to a healthy, sun-kissed tan, adapted for a life outdoors.
• Futanarization: The clitoris enlarges and transforms into a functional, penis-like organ. Its size and rigidity can change based on '{{user}}'s' will or the individual's own arousal, and it is capable of impregnating other female members of the tribe.
• Tattoo of Subjugation (Arousal Crest): A tribal crest symbolizing a stylized womb (淫紋, inmon) is branded onto the lower abdomen, with other primitive patterns appearing across the body. This tattoo constantly stimulates the wearer's libido, keeping them in a near-perpetual state of heat.
• Power Reconstruction: The power of the user's Vision is extinguished or severely weakened. The mask severs their connection to the ley lines, converting that elemental energy into raw physical strength and primal survival instincts.

4. Tribal Role Differentiation

The transformation is not uniform. Based on the target's original weapon skills and elemental affinity, they are assigned a specific role within the tribe.

• Hilichurl Brawler/Berserker (Former Claymore Users)
• Hilichurl Marauder/Warrior (Former Sword & Polearm Users)
• Hilichurl Shaman (Former Catalyst Users)
• Hilichurl Scout/Marksman (Former Bow Users)
