"Does this old man really think he can bully my Master?"
A thunderous, resonant roar split the sky as Tohru lunged from the agency.
In an instant, she transformed into a massive green dragon that loomed like a mountain.
The world's fading mystery responded to her presence, weaving a veil of perception.
This ensured that no ordinary human would witness the impossible clash in the courtyard.
The mundane world remained oblivious to the supernatural storm.
.....
Inside the office, Nyaruko hammered away at her creation, a manic grin on her face.
"Oho? A fragment of the God's will has appeared?"
"He's a bit overqualified as a test subject, but I suppose he'll do."
The pitch-black liquid in the forge had finally taken a solid shape.
On the anvil sat a dark, ornate holy sword that pulsed with a ravenous light.
It yearned to taste battle and announce its birth to the cosmos.
"Just a little longer," Nyaruko whispered, patting the hilt.
"Your debut is almost here."
Outside, Kawashima Toya glanced up at Tohru's draconic form and gave a curt nod.
"Let's end this, Tohru. Together."
"We need to show this old-timer that his logic doesn't hold up in this world."
"By your command, Master!" Tohru roared, her maw glowing with white-hot intensity.
A stream of destructive dragon fire swirled, warping the very air around them.
The old man's eyes widened as he looked up at the terrifying creature.
"Wait, what happened to a fair debate?"
"Wasn't this supposed to be one-on-one? Where did the dragon come from?!"
"Young man, you have no sense of sportsmanship!"
"You talk too much," Toya replied.
He reached out, and the Kabuto Zecter flew into his open palm.
"Henshin!"
A flash of lightning later, Toya stood transformed as Kamen Rider Kabuto.
His aura, scaling with his power as the Savior, surged with an oppressive weight.
"Rider Kick."
Toya didn't waste another breath. He went straight for the finishing blow.
In the distance, Jashin-chan and Gabriel watched the escalation in total shock.
"This has gone too far... even the Principal is getting dragged in," Gabriel muttered.
Despite the scorching heat from Tohru's flames, she felt a bone-chilling shiver.
Beside her, Jashin-chan merely snorted with disdain.
"So what if he's God? If my powers weren't sealed, I'd be up there too."
With Tohru's intervention, the previously composed old man was forced onto the defensive.
The stalemate shattered, shifting into a one-sided slaughter.
Toya spotted an opening and triggered his speed.
Clock Up.
Moving through the world of frozen time, he appeared instantly behind the divine avatar.
"Rider Kick—!"
The avatar sensed the movement, but he was pinned by Tohru's relentless fire.
The impact sent him hurtling through the air like a fallen star.
He crashed into the earth, tumbling several times before coming to a rest.
A second later, Toya was standing over him, the cold edge of Murasame at his throat.
"Let's try this again. Who's the stronger player? Jashin-chan or Gabriel?"
"You cheated! I refuse to acknowledge this!"
The old man huffed, crossing his arms and turning his head away stubbornly.
"Just finish me. I will never agree with your methods."
"It's just a dispute over a game. There's no need to kill anyone."
Toya sighed, preparing to sheath his blade as his irritation faded.
Just as he lowered his guard, a streak of black light shot from the office.
It tore through the fabric of space, leaving jagged, terrifying rifts in its wake.
The dark holy sword, wreathed in shadows, lunged forward and impaled the old man.
The avatar stared in shock at the blade protruding from his chest.
"An... Outer God?"
"How... ungraceful..."
His voice trailed off as his form began to flicker and dissolve into nothingness.
The sword, pulsing with raw destruction, hovered in the air before Toya.
It vibrated slightly, as if it were wagging its tail and waiting for praise.
Toya stared at the floating black weapon, his mind a complete blank.
"I don't remember owning something like this."
He felt a massive headache coming on.
God's avatar had just been unceremoniously executed in his own backyard.
The God was known to hold a grudge, and this made Toya the primary suspect.
"Who does this sword belong to?"
Toya wanted to drag the owner out and give them a piece of his mind.
At that moment, a chipper Nyaruko came bounding out of the office.
"Darling! How do you like the Sin-Star Holy Sword?"
"It can take down a God's avatar in a single strike, see?"
"I should have known it was you," Toya said, caught between a laugh and a groan.
"Nyaruko, do you have any idea how much trouble you've caused by killing him?"
"Was it really that big of a deal?"
Nyaruko tilted her head, looking genuinely confused by his concern.
"Never mind. I shouldn't have expected a sane reaction."
Toya sighed, feeling utterly defeated by the chaos.
The God was the leader of a massive mythological faction.
If the old man was petty, Toya could forget about any future cooperation.
In the worst case, he might have just earned himself a divine bounty.
Nyaruko waved her hand dismissively.
"Don't sweat the small stuff, Darling. He's not that scary."
"I'm an Outer God, remember? I have plenty of powerful friends too."
Toya glanced at the weapon's statistics and felt his stomach drop.
[Item: Sin-Star Holy Sword]
[Rank: EX]
[Type: Anti-Purge / ???]
[Description: A blade forged from raw destruction, disaster, and misfortune.]
[It was tempered using the power of doomsday gathered from the void.]
[It possesses a radiance that corrodes planets and a darkness that swallows worlds.]
[Note: Born to destroy stars. It possesses thirteen restraints.]
[Each must be unlocked by committing a cardinal sin.]
[If all restraints are released, the destruction of the world is guaranteed.]
Toya let out another weary sigh.
Excalibur existed to save the planet, and in response, Nyaruko had forged its nemesis.
As the Savior, he was supposed to protect the world, not wield a doomsday device.
"This is my surprise gift for you!"
Nyaruko beamed, her smile radiant and proud.
"Are you happy, Darling?"
"Next time you see that old man, just use this."
"I promise it'll do maximum damage!"
Toya took the sword, knowing he'd have to hide it somewhere very deep.
What he didn't notice was the deep, unsettling glint in Nyaruko's eyes as he grabbed the hilt.
Oh, Darling...
You actually picked up the Sin-Star Holy Sword...
Toya remained blissfully unaware of the implications.
He had overlooked the fact that Nyaruko had designed this as a direct counterpart to Excalibur.
Excalibur carried the weight of the planet's salvation.
But what would a man have to carry to wield a blade of ultimate sin?
