In the original work, Velzard was a complete battle maniac.
Later on, she even deliberately allowed herself to be controlled by angels just to fight Guy at full power.
Of course, surveillance was part of her mission.
But compared to her mission, what Velzard truly desired was the thrill of defeating powerful opponents.
In her eyes, Guy was the strongest being in the world.
That was why remaining at his side and seeking an opportunity to defeat him became the purpose of Velzard's life.
Rin understood this.
So.
You want a worthy opponent?
Then I'll give you one!
Rin would use overwhelming power to shatter Velzard's idealized image of Guy.
And then, he would tell her—
The strongest isn't in your past, but standing right before you!
"This level of magicules..."
"So, so terrifying."
A Dragon Kind, renowned for its immense magicules and seen as a natural disaster, was now being overwhelmed by someone else's power.
Who would believe it?
But the truth was laid bare before Shizue.
As Rin's subordinate, Shizue could sense the sheer scale of Rin's magicules, but she wasn't frightened into silence. She could still think clearly.
Otherwise, with her level of strength,
Facing nearly 250 million magicules, she wouldn't even have time to react before being crushed outright!
"You little brat..."
Velzard admitted that Rin was incredibly strong.
But that didn't mean he had the right to look down on everyone else!
"Don't tell me you think that just having a massive amount of magicules is everything?"
If fights between monsters were simply contests of magicule volume, what would be the point of battle?
Why not just line up and compare numbers?
Take Veldora, for example. His magicules exceeded Velzard's.
But she had been beating him up since they were kids.
Hmm, Veldora really was a bit of a disgrace.
Despite possessing over 80 million magicules, and being just half a step away from entering the 100 million mark of God's Domain in terms of quality,
He was still defeated by the strongest Hero, who only had a Unique Skill.
That was a Unique Skill, not an Ultimate Skill!
For a Dragon Kind to be taken down by a Unique Skill, no wonder the Frost Dragon looked down on him so much.
You have to understand, the bottleneck for a Unique Skill user was around 1 million magicules, which corresponded to the Demon Lord Seed level.
Above that was the 10 million threshold of the Calamity Domain, and surpassing 100 million brought you into God's Domain.
These three realms, even without skills, could suppress weaker beings by magicule quality alone.
Just like Rin right now.
With 250 million magicules fully unleashed, the aura of God's Domain was on full display.
Veldora and the Frost Dragon, who had not yet reached that realm, could already sense the massive difference between them.
"You're right, magicules aren't everything~."
"But did I say I only have magicules?"
Rin maintained the pressure of his magicules as he slowly raised his hand. "Next, I'll show you the difference between us."
"Then, you can compare for yourself."
"Between me and Guy, who defeated you, who poses a greater threat to this world?!"
"..."
Velzard understood what Rin meant.
If Rin was stronger than Guy, then there would be no point in monitoring Guy anymore.
It would be better to stay by Rin's side to prevent him from destroying the world.
And not just that.
If Rin could display power that could overwhelm Guy, Velzard could finally be free of her mission.
Because even if Guy were to betray his oath and harm the world.
Rin would be the one to put him down.
"As expected of Big Brother's successor!"
"This spirit..."
Veldora said, "I acknowledge you!"
"Hmph."
The corners of Velzard's mouth curved upward slightly, clearly pleased with Rin's confidence and dominance.
Compared to that idiot Veldora, Rin was far more in line with her ideal image of the Star King Dragon's successor.
"Then let's begin."
After saying this much, Velzard had no reason to refuse. "As long as you can defeat me and Veldora, I'll acknowledge that you possess power comparable to Guy."
"Just acknowledge it?"
"Save the big talk until after you've beaten me!"
"Heh, as expected from a Dragon Kind... what a..."
Rin slowly closed his eyes. When he opened them again, his heterochromatic eyes had transformed into majestic, sacred dragon eyes. "Unless I beat you into submission, you won't listen honestly."
"You little brat!!"
Rin's words immediately provoked the Frost Dragon.
How dare a twenty-something kid speak to his elder sister like that?
Velzard swore she'd teach Rin a lesson!
Crack!
Crackle~
Crack crack crack crack...
Just as Velzard was about to strike, crisp cracking sounds echoed through the surrounding space.
Bang!!
Before she could react—
Velzard, Veldora, Shizue, and even Rimuru, who had been inside Rin's sleeve, were all swept into a turbulent flow of space-time.
"What is this?!"
Shizue felt her vision blur.
By the time she could see again, what stretched out before her was a vast galactic river of stars.
Giant planets, nebulae spanning countless light-years, and twisted black holes that looked capable of devouring all things.
Astronomical phenomena flashed before Shizue's eyes in rapid succession.
Finally, the image froze on a barren, gray-white land.
This was a planet without an atmosphere.
It resembled the Moon from Rin's memory, except it was much, much larger. Almost the size of the Sun.
"Let this be our battlefield."
Rin calmly raised his hand and lightly tossed Rimuru from his sleeve toward Shizue, who stood in the distance. "Shizue, take care of Rimuru for me."
Catching Rimuru in a panic, Shizue looked at Rin with worry.
"No need to worry..."
Rin turned his back to her with confidence. "I'll win."
"Over here!"
Velzard floated in the void, looking down at the gray-white land beneath her feet. Her expression had never been this serious before.
"Time and space magic?"
She looked around, then turned her gaze toward the distant star-filled sky.
And then, she confirmed it.
"This... this is all real!"
At that moment, Velzard realized a possibility. "This is a world... a complete universe!"
"He transferred us out?"
"The laws here are different from the Cardinal World."
Veldora also floated beside Velzard, analyzing the situation. "Could this be an Otherworld?"
