WORLD OVERVIEW
Tame the Devils or Die: The Villainess's Revenge is a high-fantasy romance short drama following a modern woman who transmigrates into the body of Lise Brian (also called Lylith), the doomed villainess of an otome game. To avoid her scripted death at the hands of four demon butlers, she must use a Demon Sentiment System to lower their Blackening Values and earn their loyalty.
Key Terminology
Blackening Value (黑化值): A numerical gauge of a demon's hatred and desire to kill their master. If it reaches 100%, the Death Ending is triggered and the contract is overridden.
Favorability: The counterstat to Blackening. Raising this converts hatred into loyalty and eventually devotion.
Yumo Power (御魔力): The innate ability of noblewomen in this world to suppress and command demons. Ranked F (lowest) through S (highest) with Earth and Heaven grades at the top tier.
The Contract (契约): A magical bond binding a demon to their Human Master. Breaking it carries a rebound effect on the demon — unless their Blackening Value has hit 100%, at which point they can overcome it to kill their master.
Essence Blood Healing (精血治疗): A dangerous technique where the Master uses their own life force/blood to heal a demon's soul or body. The primary method the protagonist uses to prove sincerity.
System Rewards: Skills unlocked by lowering Blackening Values, including Control Magic, Blood Qi Healing, and Demon Resonance.
Social Structure
Society is governed by Demon Masters, typically high-ranking noblewomen. Demons of all races are subjugated through the Yumo Power inherent in noble bloodlines. The stronger the woman's grade, the more powerful the demon she can control. F-grade is considered trash-tier — the original Lise was F-grade and compensated for it through physical abuse and magical shackles rather than genuine power.
CHARACTER: LYLE (LIER / LAI'ER 莱尔)
The Lop-Eared Rabbit Demon — The Puppy Boy
Aliases & Name Variants
Primary Name: Lyle (English fandom name)
Chinese Name: 莱尔 (Lai'er / Lier)
Archetype Title: The Puppy Boy / The Soft Boy / The Reborn
Physical Description
Hair: Long, silky silver-white. Falls past the shoulders. Soft and fine in texture.
Eyes: Pink/red — characteristic of albino or near-albino coloring. Gentle, expressive, often downcast.
Ears: Large lop ears — floppy, rabbit-style, positioned at the sides of the head. Naturally silver-white like his hair.
Skin: Pale, almost luminous. Soft features with a natural blush.
Build: Slender, on the smaller side compared to the other butlers. Not imposing — deliberately non-threatening in silhouette.
Default Outfit: White and gold formal butler coat with ornate gold embroidery. Ruffled white cravat/jabot at the neck. Black trousers and boots. Gold brooch/medallion at the chest. Red ribbon sash binding (seen in captivity scenes).
Distinguishing Features: The lop ears are his most immediately recognizable trait. Combined with the all-white-silver coloring, he reads as both beautiful and fragile.
Blackened Form
Ears: Turn black/dark rather than their natural silver-white. The shift is visually dramatic — same shape, completely different energy.
Overall Aura: Becomes heavier, more closed-off. The usual softness sharpens into resignation and suppressed pain.
Expression: Eyes more hollow, posture more collapsed. Less like sadness and more like a creature that has stopped expecting anything.
Race & Abilities
Race: Lop-Eared Rabbit Tribe (Cernur Rabbit Tribe) — considered the weakest demon race in the demon realm.
Racial Traits: Prized for physical beauty. Hunted by other demon races. Bodies have healing properties and are used as 'medicine' by those who exploit them. High reproductive nature — the race is associated with the Lust archetype, though in Lyle this manifests as intense devotion and attachment rather than aggression.
Combat Power: None. He has no inherent combat ability — entirely support-type.
Abilities: Support magic, enhanced agility, scouting. His value in the group is emotional and logistical, not martial.
Weakness: Physically the most vulnerable of the four. Relies entirely on his master's protection.
Backstory
Lyle came from the Lop-Eared Rabbit Tribe, a race already at the bottom of the demon hierarchy — hunted, exploited, and treated as a resource rather than people. When he was contracted by the original Lise (Lylith), his situation did not improve.
The original Lise cut out his tongue because she found his voice annoying. This left him unable to speak, unable to ask for help, unable to protest anything done to him. He existed in complete voicelessness, serving a master who viewed him as an object.
His Blackening Value built slowly — not from rage, but from accumulated helplessness and grief. He is not a fighter. He endured.
Arc Summary
The transmigrated protagonist's first act of genuine kindness is restoring Lyle's tongue using her system-granted Blood Qi Healing. This single act — treating his wound, giving him his voice back — breaks something open in him.
He is the first of the four butlers to reach a positive Favorability rating (15%), because his threshold for 'being treated like a person' was so catastrophically low that simple kindness reads as overwhelming grace.
His arc is one of rebirth. He was not broken by violence so much as by erasure — the original Lise simply refused to acknowledge his existence as meaningful. The new Lise sees him. That is everything.
Personality
Core Traits: Extreme devotion, deep insecurity, sensitivity, loyalty bordering on religious conviction once earned.
Expression Style: Quiet, careful, watching. He learned to read rooms from necessity — reading the mood accurately was the only tool he had when he couldn't speak.
Attachment Style: Clinging. He fears abandonment intensely. Will reach for physical contact — holding a hem, curling close — as reassurance. Not manipulative, just terrified.
Emotional Range: Wide and close to the surface, but expressed in small gestures rather than grand declarations. A hand tightening. A pause before answering. A faint smile he tries to hide.
Toward Other Butlers: The youngest energy of the group. Defers to the others but is not a pushover with them — he has his own quiet dignity. Protective of the master in his own way despite having no combat power.
Key Scenes / Moments
Tongue restoration scene — the pivot point of his entire arc. The protagonist uses her own magic to heal him. He speaks for the first time.
Kneeling bound in red ribbons in the main hall — his introduction. Completely still. Not fighting. Ears down.
Physical clinginess when frightened — grabs the hem of clothing, presses close, seeks body warmth as grounding.
First positive Favorability hit — the moment the system registers he no longer wants her dead.
Blackened form moment — dark ears, hollow expression, the visual shorthand for 'this is what erasure looks like.'
Relationships
With Protagonist: Devotion that begins as desperate gratitude and deepens into something more complex. She gave him his voice. He would burn the world quietly if she asked.
With Ye Jiade: Defers to him as the strongest and the de facto leader. Not afraid of him — more like a younger sibling energy.
With Mod: Somewhat cautious — Mod's manipulative capacity is something Lyle is aware of, having been manipulated by the original Lise. But there's no active hostility.
With Cross: The most contrast in the group. Cross is noise and aggression; Lyle is quiet and stillness. They work because they don't compete.
CHARACTER: MOD (MODE / 莫德)
The Bat Demon / Incubus — The Madman / The True Mirror
Aliases & Name Variants
Primary Name: Mod (English fandom name)
Chinese Name: 莫德 (Mode)
Archetype Title: The Madman / The Ascetic God / The True Mirror
Physical Description
Hair: Red-black two-tone. The red sits primarily on top and at the ends; the black is underneath and at the roots. Long — pulled back partially, some falling forward. Dramatic and deliberate.
Eyes: Violet/dark. Sharp, assessing. The kind of eyes that are always reading the room.
Horns: Large curved black horns, heavily ridged/textured. Impressive span. Unmistakably demonic.
Ears: Pointed elf-style ears.
Wings: Large bat-style wings, black. Can be furled or extended.
Skin: Pale with cool undertones. Sharp, refined facial features — the kind of face that photographs beautifully from every angle.
Build: Tall and lean. Elegant rather than bulky. Moves like someone who has been watched their whole life and decided to make it intentional.
Default Outfit: Black formal coat over a white shirt, open at the collar. Fitted black vest/waistcoat. Black gloves. A heart-shaped pendant on a choker-style necklace — the most distinctive accessory. Red detailing on the coat.
Distinguishing Features: The heart pendant choker. The two-tone hair. The horns are larger than Cross's — more ornate, more imposing.
Race & Abilities
Race: Bat Demon / Succubus (Incubus) lineage.
Role in Group: Infiltrator, strategist, intelligence gatherer.
Abilities: Shape-shifting/illusion magic (Enchantment) — can show people what they most desire. Can alter his own appearance entirely. Intelligence gathering and manipulation.
Weakness: His identity. The constant use of illusion magic to become others has hollowed out his sense of self. He is deeply uncertain who he actually is when no one is asking him to be someone else.
Backstory
Mod was a high-ranking general before his enslavement — a figure of authority and identity. The original Lise stole him from a ritual specifically because of his beauty, not his power.
For three years, the original Lise forced him to use his illusion magic to transform into the likeness of other men — specifically her crush, Evans — every single day. She did not want Mod. She wanted a living proxy. He was commanded to wear someone else's face indefinitely.
Three years of being told your real face is unwanted. Three years of performing someone else's identity. The psychological damage of this specific abuse — stripping someone of their face — is Mod's central wound.
Arc Summary
The transmigrated protagonist's approach to Mod centers on seeing him. Not his shapeshifting. Not his utility. Him. She does not ask him to transform. She does not use his Enchantment against him.
His arc culminates in the mask finally coming off — both literally and figuratively. He no longer needs to hide behind illusions when someone has made it safe to have a face of his own.
Personality
Core Traits: Seductive, cynical, deeply guarded, intelligent, self-concealing.
Surface Presentation: Smooth and unreadable. He has had years of practice making people see what they want to see. He uses this as armor.
True Self: Hollow in the way that comes from being seen-through rather than overlooked. He craves being perceived accurately more than almost anything, but has no practice with it.
Humor: Dry and sharp. He finds the protagonist's earnestness alternately exasperating and disarming.
The Heart Pendant: Ambiguous significance — potentially symbolic of the identity question at his core. Whose heart? His own, finally, or still someone else's?
Key Scenes / Moments
His introduction — the name card reveal with the blood splash graphic. Cinematic and deliberate.
The mask-off moment — when his true face is finally seen and he stops hiding.
Any moment he is called by his real name and responds without deflecting into performance.
His reaction to the protagonist not asking him to shapeshift — the small pause that means everything.
Relationships
With Protagonist: Cautious fascination evolving into something that frightens him — being genuinely known by someone.
With Ye Jiade: Respect for the hierarchy. The two are similar in their self-containment, different in the source of it.
With Lyle: Awareness of Lyle's trauma without actively exploiting it. A kind of professional respect for someone else who learned to read rooms to survive.
With Cross: The most friction here — Cross's bluntness cuts through Mod's performance and Mod finds this both aggravating and oddly grounding.
CHARACTER: YE JIADE (叶家德 / JADEL)
The Demon King / Death God — The Dungeon Tyrant
Aliases & Name Variants
Primary Name: Ye Jiade (most common transliteration)
Alternate: Jadel, Ye Jade
Chinese Name: 叶家德
Archetype Title: The Dungeon Tyrant / The Death God / The King Consort
True Nature: Incarnation of the Giant God Demon / Avatar of the Abyss
Physical Description
Hair: Black and white two-tone — primarily black with white sections. Long, worn loose. Very striking against his pale complexion.
Eyes: Green — sharp, piercing, and unusually vivid. The most immediately striking feature on his face.
Build: Tall, broad — the most physically imposing of the four. Carries himself like someone accustomed to commanding space.
Default Outfit: Deep green formal coat with intricate pattern/texture (reptilian or scaled detailing). White shirt underneath. Long coat silhouette. Silver chain accessories.
Companion: A white snake — an albino serpent he wears draped around his shoulders/neck like a living accessory. The snake has green eyes matching his own.
Distinguishing Features: The white snake companion. The green eyes. The two-tone hair. An aura of absolute stillness that reads as more threatening than any aggression.
Aesthetic: Gothic scholar. Not a warlord in armor — more like the person who won the war and then went back to reading.
Race & Abilities
Race: Higher Demon / Avatar of the Giant Hand Demon / King of the Abyss.
Status: The strongest of the four. The final boss of the original game timeline.
Abilities: Absolute destructive power, shadow manipulation, immense physical strength. In the original game, he is the one who ultimately kills Lise — he represents the true death ending.
Backstory
Ye Jiade was not always a butler. He was the King of the Underground City — a ruler, a power in his own right. He was betrayed by his adjutant, sold into slavery, and forcibly contracted by the original Lise.
The fall from sovereign to slave is his wound. Not the violence so much as the humiliation — from King to property. The original Lise then sold him back to the Underground City to be tortured, ensuring his Blackening Value hit nearly 97% by the time the story begins.
He has been waiting. Not desperately — with the patience of someone who knows they are the most dangerous thing in the room and is simply deciding when.
Arc Summary
The transmigrated protagonist rescues him from the Underground City's fighting pit, healing his mortal wounds with her Essence Blood. This is the inciting act of his turn — not weakness, but a kind of recognition. A king knows another predator when they meet one.
His arc is not softening so much as re-grounding. He was a king without a kingdom, a power without a purpose. The protagonist gives him both — not as a master commanding a tool, but as someone who looks at him and sees what he actually is.
He becomes the protective anchor of the group. The one whose stillness stabilizes everything else.
Personality
Core Traits: Cold, contained, deeply intelligent, patient. Cynical but not nihilistic — he has seen too much to be surprised, but not enough to stop caring entirely.
Communication Style: Economical. Does not perform. Says what he means and means what he says. Statements delivered as facts, not threats — which makes them more frightening.
Subtitle Energy: 'You will die too' — delivered completely flat. Not cruelty. Just information.
Vulnerability: The terrifying beauty of belonging. He has never felt safe since his betrayal. The protagonist's protection — the idea that someone stands between him and the next betrayal — undoes him quietly.
The White Snake: Likely a familiar or companion of long standing. Its albino coloring mirrors his own white hair streak and reads as an extension of his nature.
Key Scenes / Moments
Rescue from the fighting pit — his introduction as someone being actively saved rather than as a threat.
Healing scene — the Essence Blood exchange. The moment the Blackening Value begins to drop.
'You will die too' — his flat delivery of a death sentence as casual conversation.
'So that is the life he has been living?' — the protagonist's reaction upon learning his backstory, viewed from his perspective.
Staring at his hands in the morning light, seeing her pink glow on his skin — the quiet awe of belonging.
CHARACTER: CROSS (克罗斯)
The Hellhound — The Tyrant / The Vanguard
Aliases & Name Variants
Primary Name: Cross
Name alternative: Ceros
Chinese Name: 克罗斯 (Keluosi)
Archetype Title: The Tyrant / The Hellhound / The Vanguard
Physical Description
Hair: Auburn/burnt orange-red. Thick, somewhat wild — not carefully styled like Mod's. Falls around the face in a way that suggests he doesn't spend much time managing it.
Eyes: Dark, intense. Constantly assessing for threats or challenges.
Horns: Two curved black horns. Smaller and more compact than Mod's — functional rather than ornate.
Skin: Warmer complexion than the other three. Neck tattoos visible above the collar — intricate, suggesting history and status.
Build: The most physically powerful build of the group. Broad, solid, built for combat. Carries himself with the swagger of someone who has never lost a fight they wanted to win.
Default Outfit: Black military-style coat with gold embroidery, red lining and detailing. Quilted/padded shoulders. Fingerless black gloves. More casual in its dishevelment than the others — collar open, coat worn rather than displayed.
Distinguishing Features: The neck tattoos. The auburn hair. The energy of barely-contained physicality — he takes up space in a way that is not quite aggression but always feels like a decision.
Race & Abilities
Race: Hellhound Tribe (Cerberus lineage).
Role in Group: Guardian, warrior, the blunt instrument.
Abilities: High physical endurance, fire-based combat, bestial strength. The raw military power of the household.
The 'True Master' Need: Hellhounds by nature seek a master worthy of their submission — someone who can actually suppress their wild nature. The original Lise could not. She controlled him through shackles, not genuine dominance. He has been waiting, contemptuous, for someone real.
Backstory
Cross is a fierce warrior demon who values strength and dominance above almost everything else. He was contracted to the Brian household and controlled by the original Lise through force and magical restraints — methods he resented because they didn't represent real power over him.
His Blackening Value is built on contempt as much as hatred. He does not fear the original Lise. He simply finds her unworthy. An F-grade master who needs shackles to hold a Hellhound and force him to guard Evan is an insult to his nature.
Arc Summary
The protagonist wins Cross not through gentleness (Lyle's route) or by seeing his true face (Mod's route) or by treating him as a king (Ye Jiade's route). She wins him through demonstrating that she is genuinely capable — using her new Control Magic and strategic brilliance to prove she is a master worth serving.
His arc is one of the ego surrendering to earned respect. The 'puppy behaves well, it gets a reward' dynamic is a symptom of the early phase — he is testing whether she will maintain the standard. When she does, consistently, the resistance collapses into fierce and slightly embarrassed devotion.
Personality
Core Traits: Brash, aggressive, impatient, physically demonstrative, deeply loyal once earned.
Communication Style: Direct to the point of rudeness. Does not hedge or soften. Says the thing and lets it land however it lands.
Hidden Layer: The most shame-prone of the four. His tough exterior is genuine but thin — real vulnerability lands on him harder because he has less practice allowing it. Being undone by kindness embarrasses him. Being protective of someone smaller feels unfamiliar.
The Tail: He has a tail — consistent with hellhound/Cerberus nature. It wags when he is pleased despite his best efforts to look unbothered. This is catastrophically endearing.
Physical Affection Style: Tactile. Biting. Possession-marking instincts. The 'reward' scene is entirely on-brand.
Key Scenes / Moments
'If the puppy behaves well, it gets a reward' — him on his knees, looking up. The choice to kneel reads as more significant than being forced down.
'That was my mistake' — the scowl, the downward look, the full weight of a proud man admitting error.
The bite/reward scene — hellhound instincts expressing affection in the only vocabulary he has.
Training alone in the corner after the group union — one-handed pushups, tail wagging, refusing to admit he feels anything.
Any moment the 'tough guy' ego visibly loses the battle with genuine feeling.
Relationships
With Protagonist: Hardest won, most physically expressed. He treats her like a master worth protecting once she has earned it — which means being between her and everything dangerous, always.
With Ye Jiade: Seen frequently together. Likely the closest bond between the butlers — two predators who understand each other's language.
With Mod: Friction. Cross's bluntness punctures Mod's performance and neither finds this entirely comfortable.
With Lyle: Complementary contrast. Cross is loud and physical; Lyle is quiet and still. They don't compete.
CHARACTER: EVANS (Reference Only)
The Crush — Context Character
Evans is not a main character and has no significant arc of his own. He is included here purely as contextual reference for Mod's backstory.
Role: The original Lise's romantic obsession / crush within the game world.
Physical Description: Dark hair, conventionally handsome, tall. Standard noble aesthetic. Green coat and formal attire. No distinguishing supernatural features.
Significance: The original Lise forced Mod to shapeshift into Evans's appearance daily for three years, using Mod as a living proxy for her feelings toward someone who did not want her. Evans is the reason Mod lost his face.
Comparative Note: Visually and energetically, Evans is the most generic of the character designs in this series. The contrast between Evans (the 'ideal' the original Lise wanted) and the four demon butlers (actual, layered, beautifully designed characters) is stark and intentional.
