Nobody knows how to be a villain better than me.

"Yeah..."

As the door opened and closed gently, a blush appeared on her fair face under the moonlight, and her breathing became a little more rapid.

Late at night, in Xindu, near the Fuyuki Church, in a Western-style building.

"Ouch~~, Karen, be gentle, it hurts!"

"No matter how lightly you apply it, it's useless. I can't get rid of these bruises because of the curse he cast."

Inside the room, the unscrupulous school doctor in a white coat tossed aside the cotton swabs and medicine, glanced at the little girl groaning on the bed with a helpless expression, and continued to squat on the sofa, munching on snacks while watching a horror drama, watching the bloody content on the screen with great interest.

Seeing her roommate acting as if it were none of her business, the young goddess of wisdom, wincing and gasping, pounded her pillow in frustration.

"You bastard dad, all you ever do is bully me!"

"Nonsense! In the entire Fuyuki City, besides me, who else can bully you? If we don't do something about it now, you might tear the school apart by tomorrow!"

With a disgruntled snort, Samael, who had arrived under the cover of night, habitually climbed through the window, jumped into the bedroom, and sat on the edge of the bed.

Hearing the noise, Karen tensed up, glanced back at the figure inside the room, and continued watching her show on the screen. She showed no intention of getting up to greet the godfather who had come to her door late at night.

However, the girl under the lamplight bit her cherry lips, and for some reason, she started eating much faster.

At that moment, Athena, who was lying on the bed groaning, couldn't help but protest angrily when she saw her old father enter.

"It's possible, but that doesn't mean it's certain! You can't hold me responsible just because I didn't commit a crime, can you?"

"This is called a small punishment to serve as a warning, preventing future problems!"

Hearing the goddess of wisdom still arguing vehemently in her defense, Samael snorted and slapped the little girl's swollen bottom.

"Caught red-handed, still dare to argue? Doesn't your ass hurt anymore?"

"Ouch! Be gentle!"

Athena felt a burning pain in her buttocks, grimacing and yelping as she defiantly threatened.

"Watch out, or I'll wake everyone up and sue you for child abuse!"

"Go ahead and sue me. I guarantee that everyone from the police to the judge is on my side! You still dare to be so arrogant on my turf?"

Samael chuckled coldly, immediately adopting the posture of a local bully, and then slapped him again.

However, it was indeed raised high and then gently lowered.

With outstretched fingers, he pressed them against Athena's swollen bottom and gently massaged it. As he did so, strands of ether flowed from his fingertips and seeped into the skin of this goddess of wisdom, dissolving the magical stagnation that had accumulated in her flesh.

"what……"

As the fingers kneaded, a warm current surged, bringing a tingling sensation. Athena, lying on the bed, couldn't help but slightly open her mouth, her voice changing tone.

The momentary loss of composure caused the goddess of wisdom, known for her purity, to blush. She turned and glared at the culprit beside her before burying her face in her pillow, making a low, buzzing sound like a mosquito.

As Samael massaged away the lingering magical energy he had previously planted, he couldn't help but roll his eyes and hum a disapproving spiel.

"You're thousands of years old, how can you still act like a child?"

"Tch, if I didn't cause trouble, would you have been willing to come?"

Athena muttered a remark in a low voice, then turned her face away and said no more.

"..."

Samael fell silent for a moment, a pang of guilt rising in his heart. His movements became gentler, and his tone softened.

"I told you before, I'd let you move in with me."

"I do not want it!"

Athena frowned, coldly rejecting the idea, her displeasure evident.

Why move there? To watch him fool around with those women? Or to compete with that little girl named Ilya for the daughter's spot?

Having finally managed to get ahead of the curve, he used his split spirit to break through the seal of the inner sea of ​​the star and descend to the surface.

He thought he had outmaneuvered his rivals Tiamat, Themis, Medusa, and others, but after all the hard work and travel to Fuyuki City, he found that he had lost not only his close relationship with his wife, but also his former position as a daughter.

If it were a loss to a strong opponent like Ishtar or Ereshkigal who arrived first, it would be somewhat understandable.

As a result, what she longed for was snatched away by a few humans from the real world.

How could the proud goddess of wisdom swallow this insult?

So, in a fit of anger, Athena moved to the new capital and rented a house with Karen, whom she had met on the way. They settled in Fuyuki City under the name of Karen, a distant relative.

Six or seven years have passed in the blink of an eye.

"Fine, if you're not coming, then I'll move in myself, okay?"

Knowing he was in the wrong, Samael naturally tried to appease the obviously jealous Athena with some gentle words.

"

Anyway, Ilya's all grown up now, so I promise I'll spend more time with you from now on.

"Tch, who cares..."

Although her tone was one of disdain, the goddess of wisdom's voice softened involuntarily, and even her eyebrows were filled with a hint of barely suppressed smugness.

"Um, would you like me to leave? It's 30000 yen for a private room overnight."

Just then, as the father and daughter inside the house were strengthening their bond in this way, Karen, sitting on the sofa, turned her head, glared at the two who had usurped her place, and gave a sarcastic snort as usual.

Inside the room, Athena, whose little bottom had mostly recovered from swelling, rolled over on the bed, looked back at Karen on the sofa, grinned mysteriously, and snapped her fingers.

"Snapped!"

In an instant, accompanied by a crisp snap of her fingers, several divine runes emerged from around Athena, shooting off one after another like loaded bullets in a certain direction.

"Bang bang bang bang!"

Amidst the muffled explosions and floating light patterns, Samael, caught off guard by the sudden barrage of attacks, didn't even lift his eyelids. The ether within his body automatically activated, forming a magical barrier that caused the incoming runes to be annihilated one after another, leaving him completely unharmed.

"Ah! Uh-huh..."

Strangely, Karen, lying on the sofa, suddenly trembled violently as if electrocuted. Her fair skin flushed an alluring rose-red, and a suppressed moan escaped her lips, which was then cut off by her tightly clenched teeth.

"Um, would you like me to leave? It's 20000 yen for a private room overnight."

At that moment, almost identical teasing and banter came from inside the bedroom. The goddess of wisdom, with her chin propped up by her small hand, blinked her purple eyes and watched the show with a mischievous grin, adding her own comment.

"By the way, the convenience store nearby has Okamoto 001 in stock. If you need it, I can buy it for you. It's 500 yen a box. How about that? Pretty reasonable, right, Karen-chan?"

"Heh, keep it for yourself!"

Karen gritted her teeth, turned her head, and spoke in a muffled, sarcastic voice. Then, her golden eyes seemed to glance at the small figure on the bed, and as if she had thought of something, she covered her mouth and chuckled softly.

"Pfft, I almost forgot, you self-proclaimed omnipotent, arrogant, and young... 'Little' Athena, you're not old enough to use that term yet? Aha, how pitiful."

"..."

The deliberate emphasis on the word "small," and the deliberately puffed-out chest opposite her, caused Athena's face to darken for a moment, but then her eyes lit up with a bright smile again, and she snapped her fingers once more.

"Bang bang bang bang!"

Instantly, even denser and faster divine runes converged in front of the goddess of wisdom, and then, like whistling cannonballs, continuously slammed into Samael beside her.

The ancient serpent, once again becoming the target of concentrated fire, remained as still and unmoved as an old monk in meditation.

"Ugh...!"

But in an instant, Karen, who had just recovered and was about to retort, stiffened, her long swan neck tensed, and her delicate body trembled like a sieve as she fell straight onto the sofa. Her skin was as red and hot as a boiled shrimp, and half of her pink tongue uncontrollably peeked out from the corner of her slightly parted lips, a strand of crystal saliva running down the tip of her drooping tongue and onto the floor.

At the same time, a faint red heart-shaped phantom appeared on the head with its messy, flying silver hair.

Generally speaking, this scene is called estrus.

"Oh dear, it seems you need Okamoto 001 more than I do."

Looking at her roommate on the sofa, who could only stick out her tongue and couldn't speak anymore, a certain cunning and wise goddess gave her a smug, teasing laugh.

"boom!"

However, before Athena could finish her taunting remark, she jumped off the bed and launched a close-up attack, delivering a sharp rap on the goddess of wisdom's smugly upturned head.

"Your skin's itchy again, isn't it?"

Seeing his adopted daughter and his goddaughter about to engage in an epic battle, Samael, unable to bear it any longer, slapped Athena, who was jumping around excitedly.

Immediately, Samael got up and went to the sofa. As soon as he reached out, Karen, who was lying dead on the sofa, became like a snake that had smelled its prey. Her eyes glowed red, and she showed her extremely flexible body, coiling up his arm and rubbing her crimson skin against him.

The ancient snake, used to this, yielded half of its body, letting the "koala" hanging on its body wriggle around. It raised its left hand and slightly lifted the white coat at Karen's cuff, discovering that the strip of cloth wrapped around the girl's body like a red ribbon was gradually dimming and loosening. It shook its head helplessly and muttered to itself.

"The Shroud of Relic has already slipped out of control again?"

"That's because the power of the demons is too great."

Athena stepped forward, a look of schadenfreude on her face.

As roommates for many years, and with Samael as their bond, Karen and Athena already knew a little about each other's backgrounds and some of their little secrets.

For example, masochistic spiritual mediums, demonic branding, Satanic offerings, etc.

"Bullshit, wasn't it you who randomly stuffed divine cores into her hands!"

Samael, his face darkening, deflected the blame thrown his way and bluntly named a certain culprit.

Immediately, the ancient serpent muttered words of advice to the goddaughter clinging to it, while simultaneously cupping its five fingers around Karen's head and crushing the emerging pink heart-shaped light and shadow.

"Given your obvious weakness, and the fact that she has leverage over you, why would you provoke her for no reason?"

"If I had known you and your daughter were in cahoots, I would never have believed her lies!"

At this moment, the saintess, who was lost in her daze, became somewhat more awake and couldn't help but glare angrily at her unscrupulous roommate who was secretly laughing. She felt even more depressed.

"Why are you being so fierce? Hasn't the problem you mentioned already been solved?"

Athena peeked out from behind, smiling sweetly with an innocent look on her face.

"Solve it? You have the nerve to say that!"

Upon hearing this, Kallen was immediately enraged and charged forward, baring her teeth and brandishing her claws. Athena, on the other hand, used Samael as a shield, executing a rather skillful maneuver of circling around a pillar.

Seeing that his adopted daughter and goddaughter, one big and one small, were about to start arguing again, Samuel felt a headache coming on. Helpless, he gave each of them a sharp rap on the head and pulled them apart.

The core of Amor, the Roman god of love, is the main reason why Karen experienced these symptoms.

More than ten years ago, in order to save and protect the newborn Karen, the ancient serpent planted a mark on her body, signifying that she was its sacrifice, thus preventing other evil spirits and demons from coveting the girl.

Everything went exactly as he and Kiri had predicted. For the first ten years or so, Karen grew up healthy and without illness.

However, with the lifting of the ban on the Sea of ​​Stars after the Fourth Holy Grail War in Fuyuki City and the return of the Age of Gods, Samael's power has been continuously revived.

The corresponding spiritual resonance will be fed back more strongly to Karen, who came to Fuyuki City to visit relatives.

As a demonic offering branded with a mark, it would naturally and involuntarily offer itself to the priest.

However, as a believer of the Lord, a certain saint who was initially unaware of the situation strongly resisted this feeling, so she sought help from Athena, whose identity she had learned at the time.

This ancient Greek goddess of wisdom did indeed propose a feasible solution.

That is, by implanting a divine core and utilizing divine laws, one can temporarily resist the resonance from the imprint and alleviate one's discomfort.

Originally, the battle between the gods in the Covenant War was extremely fierce, and countless gods, both great and small, perished on the battlefield.

Athena, the goddess of wisdom and war who was the main damage dealer on the battlefield, also picked up a lot of similar loot.

Therefore, I don't feel bad about giving them away casually.

Unexpectedly, after a series of tests, Karen happened to react most strongly to Amor's divinity, showing the best compatibility.

So Athena generously offered up her own collection—fragments of the core of Amor, the ancient Roman god of love.

Admittedly, with the fusion of Karen and the fragments of Amor's divine essence, her willpower increased, and the initial problem was indeed alleviated.

However, more problems followed.

Although the Amor Godhood enhanced Kallen's mental resistance to some extent, the Satanic mark within Kallen was stimulated by external forces and automatically and rapidly strengthened without Samael's control, quickly pushing back the divine law barrier automatically constructed by Amor.

From then on, every time Amor's divine law was invoked, intending to respond to the host's call, it was crushed after only a short time.

To make matters worse, Amor is the god of love, and his divine laws naturally prioritize sexual pleasure.

Each collapse of divine law causes a backlash that is reflected back onto the physical body and is continuously amplified.

Therefore, what started as a slight spiritual attachment to the priest has now turned into a naked physical desire.

Fortunately, after several reckless attempts and learning her lesson, Karen gradually became more sensible and chose a gentler approach. At the same time, she used the divine power of Amor and the Magdalene Shroud on her body, which could capture men, to release false signals, wrapping the Satanic mark and putting it into a dormant state.
