Serafall made her position crystal clear: she would never allow her little sister to be with someone weak.
And in this declaration, she found the perfect excuse to spend more time with her sister.
"You're a Maou. Are you sure this is a good idea?"
Arthur asked, his tone serious. He might not have known the intricacies of devil politics, but he was certain this would cause a stir.
"I'm positive! I've talked to Sirzechs-chan about this for a long time,"
Serafall replied with unwavering confidence.
"And besides, you're a dragon. It won't be a problem."
Dragons were immensely powerful beings, sought after by every faction.
To marry one meant securing a future of powerful devil-dragon kin, strengthening their faction immensely.
Arthur considered her words, glancing over at Sona.
Although Sona seemed bothered by her older sister's antics, Arthur knew she cared for her deeply.
'You should accept her condition!'
Great Red urged in his mind.
She wanted a strong mate for him.
'She's strong enough to satisfy you,'
Ophis added. Arthur had grown in power, and with it, his vitality had surged.
Only someone stronger than him could temper his overwhelming lust.
"Alright, let's do it,"
Arthur agreed.
"Thank you!"
Serafall beamed, while Sona merely sighed. There was nothing she could do.
She had already decided not to be concerned with his harem, and adding her older sister to the mix wouldn't be a problem.
The group gathered at the training ground.
Rias and her peerage, along with everyone else, had been summoned by Sirzechs, though they didn't know why.
Koneko was with Kuroka, their relationship mended.
Koneko was hugged tightly by Kuroka, not minding it in the slightest.
Her cat ears and tails were out, a clear sign that she had fully accepted her true self.
"Nyaan, if we don't do something, we might miss our chance,"
Kuroka purred to Koneko, who nodded in agreement.
They had decided to pursue Arthur. Kuroka longed to have many kittens with him, while Koneko, for now, simply wanted to be his little sister until she was ready for something more.
Sirzechs stepped in front of everyone and explained why they were called.
"Today, Serafall Leviathan will spar with Arthur for the marriage of her little sister... and for herself. We will all bear witness."
With that, Sirzechs cast a barrier over the entire training ground, powerful enough to contain any stray magic from the coming battle.
The air crackled with anticipation as Arthur and Serafall faced each other.
Serafall, a Maou with a Pow, End, Dex, AGI, and MAG all rated at SSS-1200+, was a force to be reckoned with.
Arthur, while at a lower Level, possessed an innate power that transcended traditional rankings.
His Pow and AGI were at S-900+, and his MAG was an astonishing SS-1087.
He was a Low Tier Godling with skills like Reality Blending and the Authorities.
This wasn't just a sparring match; it was a clash of titans.
Serafall was the first to make a move.
The Maou of Ice and Water, she summoned forth a massive blizzard that engulfed the training ground.
The temperature plummeted instantly, and sharp ice spears formed in the air, aimed directly at Arthur.
He stood his ground, a calm smile on his face.
"Don't hold back, Arthur-kun! I'm a Maou, you know!"
Serafall declared, a playful glint in her eyes, even as she unleashed her full power.
The ice spears shot forward like a volley of arrows, but before they could reach him, a shimmering golden light enveloped Arthur.
It was his Dragon's Aura, a passive skill that provided a powerful defense.
The ice spears shattered upon contact, harmlessly turning to mist.
Arthur raised a hand, and the very space around him seemed to warp.
A swirl of vibrant colors began to form, a manifestation of his Reality Blending.
The blizzard around him flickered and distorted, as if a glitch in reality itself. Serafall's eyes widened in surprise.
This wasn't just magic; it was something else entirely, a manipulation of the very laws of existence.
He launched his counterattack, not with a direct blast, but with a subtle change in the environment.
The ground beneath Serafall became slick with ice, but instead of the normal kind, it was a bizarre, chromatic ice that pulsed with energy.
She stumbled, momentarily caught off guard. It was a perfect display of his power, slowing her reactions ever so slightly.
"You're like Pandora's box, Arthur-kun!"
Serafall laughed, regaining her footing with a burst of her own power.
She conjured an enormous dragon of pure water, its form majestic and intimidating.
It coiled around her, its gaze fixed on Arthur.
"Now let's get serious!"
She shouted.
The water dragon lunged, its maw open wide, ready to swallow him whole.
Arthur remained unmoving, his Super Focus activated.
He saw the world in slow motion, the flow of magic and the movements of the water dragon clear as day.
He didn't need to dodge or defend.
He simply extended his hand, and with Dragon's heart he started to absorb the magic of the water dragon.
The dragon's form began to dissipate, its power flowing into him, making him feel even stronger.
Serafall watched in disbelief as her powerful construct was drained away.
It was understandable because she used only half of her usual power.
The air grew tense.
Sirzechs watched from the sidelines, a mixture of awe and concern on his face.
This was not the spar he had anticipated.
This was a battle between two beings who operated on entirely different planes of existence.
