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

Lucy had always been accustomed to being the undisputed, supreme entity. Following that same deeply ingrained mindset, she habitually resolved the vast majority of her conflicts through sheer, absolute power—and nothing else.

If something was difficult to comprehend or process at first, her direct solution was simple: beat the person responsible into submission first, then sit back to comprehend it later! If a situation proved exceedingly complex and intractable, it didn’t call for formulating a legendary master plan or calculating intricate strategies; it merely demanded pumping a larger volume of raw power and destructive fury! Although she was neither stupid nor reckless in combat—possessing a razor-sharp intellect and unmatched brilliance on the battlefield—she ultimately never expected to encounter an entity capable of matching and overwhelming her within her own domain in such a terrifying fashion, especially one originating from a realm like Earth, whose inhabitants she had always regarded as inferior beings.

Lucy shook her head frantically, masking her excruciating pain as she thought to herself: ’None of this nonsense matters... All that matters right now is winning, annihilating this entity, and returning to Cain!’

Cain stood rooted to the spot, completely stunned and shocked. He couldn’t believe the sheer amount of mockery and disdain that had just poured from Lucy’s lips! This was not the trajectory they were supposed to reach—not in the slightest. He hadn’t wanted to engage in this cursed battle from the very beginning; he had been dragged into it against his will, and now here he was, being insulted and belittled by the very wife he was striving to protect!

Yet how could he clarify that this entire ordeal was nothing more than a massive misunderstanding?!

It was painfully obvious that even if he tried to explain a thousand times, as long as she saw him clad in this shadowy form forged by the summoning magic, she would never believe he was her beloved husband Cain. Instead, she would remain dead set in her conviction that he was the ”Leader of the Smile Organization”!

Yet amid this disorientation, Cain suddenly realized a cold, hard truth... This childish game and futile struggle were entirely his fault! He was the one who had allowed himself to indulge her, softening his stance out of fear of hurting her or bruising her pride. But after humoring her in battle and trading blows—instead of shutting it down and settling the situation outright, something he could easily accomplish given her severe mana depletion—he had only caused the conflict to escalate into this tragic state!

His failure to deploy absolute coldness from the very first instant was the direct cause of all this blood and destruction!

In those fleeting seconds, a dark, harsh resolve crystallized in his mind. It tore his spiritual heart to shreds, yet it was the sole remaining option to put an immediate end to this absurdity! Since Lucy refused to recognize him as her beloved husband Cain, viewing him instead as an enemy ruler and rival, he had no choice but to teach her a harsh, direct lesson in humility!

Noticing that the shadow entity had halted his assault and plunged into thought, Lucy seized upon this brief distraction and the psychological imbalance her mocking words had inflicted upon her opponent’s mind. She decided to launch a sweeping, preemptive strike to finish him off once and for all!

Supreme mana surged through her exhausted magical pathways, channeling densely into the blade of her legendary sword—the Dimension-Destroyer. She charged toward the shadow entity at a mythical speed, as though her bleeding wounds and injuries had never occurred!

SWOOOOOOSH!

Lucy executed a scorching horizontal sweep, cleaving the white space as it surged toward Cain’s shadowy form... Yet, instead of blocking the attack in his usual tactical pattern...

Cain shifted the sword in his grip with a supreme technique of terrifying power and speed. He didn’t use that power to defend himself or parry her blow; instead, he aimed a direct strike straight at the blade of Lucy’s own weapon!

CLACK-CRACK-SHHHHH!

The Dimension-Destroyer sword shattered into thousands of fragments that scattered into the air, leaving Lucy frozen in utter shock and disbelief as she stared at the empty hilt in her hand!

That sudden destruction was not enough for Cain...

In those fleeting moments, while she was still reeling from the shock of her legendary sword disintegrating, Lucy felt as though she had been struck by thousands of direct punches across various parts of her body in a single fraction of a second!

When she finally raised her head and beheld the colossal, overwhelming aura that suddenly erupted from the shadow entity... she realized in that terrifying instant that all the fierce combat they had engaged in moments ago was nothing more than child’s play, and that this was his true, boundless power!

Lucy’s voice emerged stammering, thick with primal terror:

”W-Who... who are you?! What higher universe do you hail from?! Are you... one of the Ancient Gods?!”

Cain offered no answer. With absolute detachment, he simply directed a direct, focused strike straight to her face, blowing her back with immense force and sending her hurtling like a projectile into the distance, while he stood in calm stability, watching her body rocket backward through space!

This time, Lucy didn’t even attempt to halt her momentum or regain her balance... Instead, she tore open the boundary of her pure white spiritual dimension herself and fled out into the dark expanse of outer space! She burned every remnant of her mythical speed to escape through the fabric of galaxies, fleeing far away from this cosmic monster she had summoned with her own hands!

She had discovered the bitter truth far too late, unfortunately... and deep within her trembling heart, she desperately prayed that this entity would let her leave and escape with her life!

Yet her dreams and wishes were completely futile before such absolute dominance...

SHRRRRR!

Before Lucy could even process her escape route, a scorching hook punch slammed squarely into her face. Her heart beat with absolute terror and submission as she frantically searched for any exit or avenue of safety, burning what little remained of her body’s dwindling mana reserves just to put distance between them!

Yet every single time she tried to alter her direction or flee toward a new coordinate, that majestic, dark form manifested abruptly before her in a manner that invoked absolute horror! Against the pitch-black backdrop of deep space, the sight projected an overwhelming dread into her soul, the likes of which she had never tasted before!

Lucy’s pride collapsed completely. She whispered in a faint, broken voice:

”I am truly sorry... Forgive my stupidity and my insolence toward you!”

In those agonizing moments, Lucy recalled her past—when she was the one standing at the absolute pinnacle of supreme authority, while her enemies knelt at her feet, begging for mercy and forgiveness...

Yet here she was now. Driven by her stupidity and false pride, she had foolishly assumed life would grant her chance after chance to survive. Instead of fleeing from the very beginning, she had stubbornly insisted on fighting this absolute, unbeatable entity!

This wasn’t merely existing at the Truth Level... In her eyes, this presence was far mightier and more absolute than any Truth Level an entity could ever hope to attain in this universe!
