I'm Secretly the Father of the Yandere Villainess's Daughter

”Are you mocking me, Matthew?!”

The voice of Levra, the Great Demon King, erupted in a suppressed fury as he slammed his fist upon the table. ”Only yesterday, I wedded the three thousand, nine hundred and ninety-ninth (3999) wife of my life! And now, here you are, summoning me from my wedding night while my bride and I were in the very midst of discussing paramount affairs... just to utter this absurdity?!”

Levra had completely abandoned his customary silence; he had been in a magnificent celebratory mood since yesterday. He had wedded his latest bride from a novel race he had never intermarried with before—the princess of the ”Alabaster” race, a unique hybrid lineage between humans and intelligent slime entities. They possessed a semi-humanoid appearance, yet with entirely blue, gelatinous, and highly intriguing bodies.

Levra had never anticipated at the time that he would relish her rare companionship on their initial night to such an extent that he internally resolved to wed yet another woman from a different race today, thereby perfecting his record-breaking number of marriages to an even four thousand (4000)! Yet now, instead of establishing the rituals of the new wedding ceremony, he found himself compelled to attend this emergency assembly, which had been characterized as critical for the entire organization. He had been experiencing sweeping euphoria two hours prior, but now he harbored a violent urge to strangle someone!

Correspondingly, all the commanders and titans surrounding the roundtable directed burning glances saturated with wrath toward Matthew, perceiving the summon as a blatant mockery of their intellects.

Yet Matthew remained thoroughly composed, not a single hair upon his exposed face trembling. He spoke in a cold, confident tone, ”All of you are foolish and naive! Do you not comprehend that love renders the most formidable of men an absolute idiot, steering him toward the darkened abyss while he wears a smile? Our towering, magnificent Master—the man who united us all beneath a single banner, taught us the loftiest virtues, and rendered us vastly more powerful through his benevolence—is currently subjected to the most heinous forms of psychological torture and subtle exploitation by an exceedingly potent adversary, while our Master remains drowned in his illusion, completely oblivious!”

Whispers began to ignite, spreading like wildfire along the span of the roundtable, exposing an all-encompassing shock.

Suddenly, Lilith—the Supreme Succubus—stood, clad in her intensely provocative attire and enveloped by her profound, bewitching aura capable of plundering the minds of most who merely gazed upon her. She spoke in a disapproving tone, ”An adversary exploiting our powerful Master and besting him?! You are undoubtedly lying and amplifying matters, Matthew. Even I, the Supreme Succubus, could not breach the Master’s heart or influence his mind by a single inch, no matter how intensely I attempted or flaunted my charms! Utter the truth without manipulation... why are we assembled here?”

Matthew’s face remained entirely rigid and devoid of expression. He gazed at her with frigid indifference, stating, ”Hah... precipitate in rendering judgments as custom dictates, Lilith. I am aware that you will not credit my words easily, yet I swear before you all by the sanctity of the Organization...”

Matthew inhaled a profound breath, and though he lacked the knowledge of how to phrase this scandal, he summoned his resolve and delivered it all at once:

”The Master grows progressively madder day after day! He sits within his private office, shedding profuse tears while releasing foolish cackles at entirely random intervals! Furthermore, and even more catastrophic, his magical status has abruptly plummeted from the Truth Level down to merely the ’Immortal Level,’ and it appears with absolute certainty that he has forfeited the vast majority of his titanic magical capabilities and blessings! The sole verified intelligence I possess is that this woman enters the chamber with him completely solitary for a few counted minutes, and the Master subsequently emerges with the traits of a smile blended with a deep-seated sorrow upon his visage... while she, and she alone, manifests signs of absolute ecstasy and profound satisfaction upon her face!”

Every single individual seated within the grand hall was paralyzed by these shocking words, on the verge of crying out in unison: ”Impossible!” For Matthew could be rigid or sparse with his expressions, yet he never jested or manipulated matters that pertained to the safety and might of Commander Cain Oster.

Nevertheless, they all perceived that this deterioration entirely transcended the boundaries of logic. How could their majestic Master fall victim so easily into the hands of a woman?

Mayner—the King of the Righteous Sword—intervened, slamming his fist against the table as he bellowed with rage:

”Damnation! These are undoubtedly the malicious soul-stealing and demonic absorption methodologies utilized by succubi like Lilith! Confess, Lilith, was this one of your maidens whom you train secretly within the darkness? Or are you attempting to mislead us now, being the true perpetrator behind this stratagem from the very beginning?!”

Sword King Mayner harbored an absolute, unadulterated hatred for the entire demon race. Before enlisting in the Transmigrator Organization under Cain’s command, demons were his eternal adversaries upon the battlefields, and he never hesitated for a second to sever their heads. Yet Lilith, who was seated in a thoroughly relaxed and comfortable posture, turned toward him and smiled with a playful softness:

”Are you attempting to entrap me and settle your ancient scores with me, Mayner? Everyone present recognizes that you harbor an old grudge against my kin. Everyone likewise recognizes that ever since I aligned with this organization, I have entirely prohibited all those soul-absorption training methodologies, rendering them a supreme taboo within my faction. Does any among you entertain a doubt regarding this?”

Mayner countered with overt hostility, ”It is undoubtedly another demonic falsehood! You are habituated to deception and lies, being demons in the end!”

A violent brawl was on the absolute verge of erupting between these two titans, their destructive auras threatening to clash within the hall, had Matthew not intervened and instantly suppressed their energies with his potent shadow aura, glaring at them sharply.

”Shut your mouths! She does not belong to the succubus race in the slightest... yet she is undoubtedly utilizing their methodologies of energy absorption and power plundering. In fact, it appears she has evolved those methodologies to attain supreme, terrifying tiers that transcend what we can comprehend with our current minds!”

An absolute silence loomed over everyone once more. Who in the heavens could this powerful, legendary woman be, possessing the capability and audacity to inflict such a state upon their Absolute Master, rendering him this maddened and vulnerable?

Matthew did not prolong the obscurity or permit them to guess; rather, he answered them in a tone dripping with prestige and a deep-seated dread:

”It is... Lucy Montgrad!”

At that precise moment, the blood completely froze within the veins of the Demon King Levra. The bodies of several powerhouses seated around the table trembled, and the film of their dark, agonizing memories began operating within their minds with violence!

For Levra immediately recalled the ill-fated incident when he had attempted in the past, out of sheer arrogance, to request Lucy’s hand in marriage, promising her that he would consecrate the entirety of his love to her alone and would sever ties with all his thousands of wives for the sake of her eyes... yet she, in return, did not merely reject him; she severed his entire arm with sheer coldness, and was on the verge of slaughtering him and terminating his existence completely had he not gathered the entirety of his magical powers to flee in the final fraction of a second!

Everyone gazed toward Levra, who was visibly trembling while seated upon his throne, profuse sweat cascading densely from his brow. He murmured in a shaking voice:

”Then... then what precisely do you desire us to execute, Matthew, before such a monster?” Levra literally never desired to hear the name of that ill-omened woman again for the remainder of his life!

Matthew spoke with gravity and rallying intent:

”We are in dire need of overthrowing her... to distance her completely from the Master because she has behaved like a malicious parasitic entity, consuming our Lord and draining his might! I initially believed, naively, that she loved him with sincerity, yet it has been demonstrated via conclusive proof that she is merely a parasite absorbing his capabilities!”

None dared to counter or offer a notion of direct confrontation. Yet somewhere near a corner of the roundtable, a small robot child shifted, his face comprised of a digital screen displaying his cute, innocent electronic expressions; his name was ”Cutler.”

Cutler inquired in his pure, mechanical voice, ”And what is your ingenious strategy to overthrow her, Sir Matthew?”

Matthew fell completely silent... possessing absolutely no answer whatsoever! This precise inquiry was the solitary question he had desired from the depths of his heart that none would raise during this assembly.

Matthew cleared his throat with embarrassment, stating, ”In truth... I sat throughout the past ten days and resolved to sketch and draft some tactical blueprints upon paper... and I calculated mathematically that by all conventional methodologies, whether in close-quarters combat, ranged engagements, or even hidden magical influence—and everything that falls within the foundation of mana and spiritual energy among the powers we possess—we, even combined, cannot defeat her or so much as scratch her!”

The majority of those seated at the table were on the verge of rising to unleash a torrent of insults upon Matthew; for how could he summon them from their respective continents merely to declare this impotence!

The small robot Cutler inquired with digital innocence once more, ”And what regarding the unconventional methodologies?”

Matthew swallowed his dry saliva, then answered with contracted features, ”Regarding the unconventional methodologies... which encompass pleading with her, offering ourselves as magical human sacrifices to appease her, or offering to serve her for the forthcoming thousand years without rest or cessation... they were not successful strategies in my estimation, because the data indicates that she will not depart from the Master via this method either...”

Gargantuan digital question marks ([?!]) materialized upon the screen of the robot Cutler’s face: ”Then... is there any successful strategy, even by a minute percentage?”

The expressions upon Matthew’s face worsened further, and he spoke in a submissive tone, ”Yes, certainly... and there is one singular strategy that guarantees a percentage of success and survival for the entire organization reaching a full one hundred percent (100%)... which is: To do absolutely nothing at all!”

The alarming, disappointing silence returned to loom over the expanses of the grand council chamber.

Yet suddenly, the Demon King Levra burst into a loud, relieved laughter, stating as he wiped the sweat of dread from his face, ”I concur instantly with this wise strategy! In truth... a true King does not have his throne easily threatened!”

The significance behind Levra’s words was as clear as the sun to everyone; they could merely sit, offer logistical reinforcement, and wait with patience until Cain awakened from the state of emotional illusion and vulnerability he was passing through, and undertook the vengeance himself to reclaim his ducal pride and his jewel.

For in the end... a true King cannot have his throne threatened by a woman, no matter her dominion!
