In the timeless expanse of the System Space, days turned into weeks, weeks into months, and months into years—though Algernon couldn't tell the difference. Here, there was no sun to mark the passage of time, no night to grant respite.
The void of white light became his eternal companion, and his only focus was the trial laid before him.
Every time Algernon pushed his body to the brink, collapsing under the strain of channeling the Power of Destruction, the Trial Space would restore him.
Broken bones mended in seconds, torn muscles knitted themselves back together, and his spirit, battered from the overwhelming force of his power, was rejuvenated.
"Again," Algernon growled, standing amidst a storm of crimson energy, his body drenched in sweat.
The destructive aura raged around him, the sheer intensity of its power threatening to tear him apart. Yet, instead of fearing it, Algernon embraced the challenge.
Every failure taught him something new—a better way to focus his energy, a sharper control over the chaos, a deeper understanding of the storm within him.
He'd lost count of how many times he had been brought to his knees, how many times he had screamed in frustration, but he refused to give up. Each fall only hardened his resolve.
At first, mastering the Power of Destruction seemed impossible. The energy was wild, feral, and unrelenting, constantly fighting against his will. But as the years passed, Algernon's efforts began to bear fruit.
The chaotic storms of destruction became more like extensions of his will, obeying his commands. He could now summon concentrated orbs of pure destruction, each one capable of obliterating anything in its path.
He mastered ranged attacks, close-range strikes, and defensive techniques—all powered by the destructive force that had once threatened to consume him.
But Algernon wasn't content with mere mastery. He wanted to dominate the power completely, pushing beyond what even the system expected.
"Is that all you've got?" he growled, blood dripping from the corner of his mouth as he stood against yet another wave of crimson energy conjured by the System Space itself. His body was battered, but his spirit burned brighter than ever.
The System Space responded to his defiance by increasing the intensity of his training. The energy storms grew fiercer, the challenges more brutal. Algernon didn't falter.
Every time his body was broken, it was healed. Every time his spirit wavered, he rekindled it with thoughts of Rias and to become the Supreme he was destined to be.
After what felt like an eternity, Algernon stood in the center of the System Space, surrounded by an aura of absolute calm. The Power of Destruction, once a raging tempest, now flowed through him like a gentle yet unstoppable river.
His every movement exuded strength and control, his presence radiating the aura of a true conqueror.
The system's voice echoed, but this time, it carried a tone of reverence.
[You have reached the peak of Ultimate Class.]
[You now stand at the pinnacle of Tier 1.]
Algernon clenched his fists, feeling the immense power coursing through him. His once-limited abilities as a Low-Class Demon were now a distant memory. He had trained relentlessly.
The void of the System Space began to shift, the blinding light dimming slightly as the system spoke again.
["You have done well, Host. Few could endure what you have achieved. You are now ready to return to the world beyond and continue your ascent."]
Algernon exhaled, his crimson eyes glowing with determination. He had spent countless years in this timeless space, refining himself into a force to be reckoned with. But his journey was far from over.
The Power of Destruction was now his to command, but it was only a tool—one he intended to use to conquer the challenges that awaited him.
As the space began to dissolve around him, the system delivered one final reward.
["For reaching the peak of Tier 1, you have earned the title Harbinger of Destruction. This title will amplify your destructive abilities in battle and inspire fear in your enemies. Use it wisely."]
The glowing title appeared briefly in the air before embedding itself within Algernon, a tangible mark of his achievement. He smirked, the weight of his training finally giving way to a sense of pride.
"Harbinger of Destruction, huh? I like the sound of that," he muttered.
In a flash of light, Algernon was pulled from the System Space and returned to Rias's bedroom. Everything was exactly as he had left it—the warmth of Rias's presence, the softness of the bed, and the crimson glow of the morning.
For a moment, he sat in silence opening his status.

"Peak of Ultimate Class…" he muttered to himself. "Satan Class is next. Tier 2. And I'll get there in a week."
His gaze shifted to Rias, who was slowly waking up beside him. Her ruby-red eyes opened, and she smiled warmly, a soft blush tinting her cheeks.
"You're up early," she murmured, her voice still heavy with sleep.
Algernon leaned down, pressing his lips to hers in a tender kiss. Her arms instinctively wrapped around his neck, pulling him closer.
"Just preparing for what's next," he said softly, pulling back slightly to meet her gaze. "I have plans to set in motion, but before that…"
He didn't finish his sentence, letting the kiss deepen instead.

After their lighthearted morning session, Algernon dressed swiftly in his combat gear, his black and crimson cloak fluttering behind him. He walked Rias to the academy gates, the Kouh Academy looming in the distance.
As Algernon and Rias walked toward the gates of Kouh Academy, the usual hustle and bustle of students coming and going seemed to pause.
The crimson-haired beauty of the Gremory Clan, the girl regarded as one of the most breathtaking and unattainable students in the academy, was holding hands with a boy—a boy who radiated an aura of power and confidence that none could ignore.
Heads turned. Whispers spread like wildfire among the students.
"Is that Rias… holding hands with someone?"
"Who is he? He's not even in the academy, is he?"
"Damn it, that lucky bastard!"
Algernon, unfazed by the stares and murmurs, walked with his usual calm demeanor. His hand gripped Rias' gently yet firmly, a silent declaration that she was his and his alone. Rias, on the other hand, seemed to enjoy the attention—or rather, she enjoyed flaunting their closeness.
When they reached the gate, Rias turned to him, her ruby-red eyes shining with affection. "I'll see you later, okay? Try not to cause too much chaos."
Algernon smirked. "No promises."
Instead of letting go, Rias stepped closer, wrapping her arms around his waist in a warm hug. Her head rested briefly against his chest, and Algernon instinctively placed a hand on her back.
But it was what happened next that left the male students utterly devastated. Rias pulled back just enough to stand on her toes, pressing a soft kiss to his cheek.
"Take care," she said with a playful smile before turning and walking toward the academy building, her crimson hair flowing like silk behind her.
Algernon stood there for a moment, watching her leave. A faint smile tugged at his lips as he touched the spot where she had kissed him. "She's something else," he murmured before leaving.
As Rias walked into the academy, the stunned silence among the male students finally broke.
"Did… did Rias Gremory just kiss that guy?"
"Who even is he?!"
"This can't be happening! How did he—what did he—?!"
"He must be someone crazy strong… or rich… or both! Damn it!"
Some of the male students glared jealously at the spot where Algernon had stood moments ago, their frustration palpable. A few even resolved silently to figure out who this mysterious man was, though deep down, they knew they couldn't compare.
Meanwhile, Rias walked into the academy with a serene expression, her heart fluttering slightly from the morning's events.
She loved how Algernon didn't shy away from their relationship, and she took quiet satisfaction in the reactions of the onlookers. After all, Algernon wasn't just anyone—he was hers.
A swirl of crimson energy heralded the arrival of a lone figure on the outskirts of Lilith, the sprawling, gothic heart of the Demon Realm.
The figure stood tall, cloaked in a flowing black-and-crimson mantle, his face obscured by a sleek black mask adorned with faint, glowing red etchings that radiated an air of ominous power.
The streets of Lilith were alive with activity, a cacophony of merchants hawking rare magical goods, demons sparring in open challenges, and the constant hum of dark energy saturating the air.
At the center of it all stood the Grand Arena, an architectural marvel of black stone carved with glowing crimson runes that pulsed rhythmically, as though alive.
The masked figure took a step forward, the faint clink of his boots on the obsidian road drawing attention. Conversations died down as heads turned to watch him pass. His aura, oppressive yet controlled, radiated a presence that demanded respect.
"Is that him?" a demon hissed under his breath, his glowing eyes darting nervously.
"Yeah… that's Azeroth," another whispered, his voice trembling with awe. "The one from the arena. The undefeated challenger."
The name Azeroth was already etched into the annals of the Grand Arena's history. Months ago, when he was still a High-Class Demon, he had stormed the arena with a vengeance, defeating every challenger who dared to face him.
His unmatched speed, cunning strategies, and relentless determination had left audiences in awe, earning him the title The Undefeated Masked Warrior.
Yet, even in those days, he had never revealed the full extent of his power. His victories were hard-fought, achieved through precision and skill rather than overwhelming force.
The audience had speculated endlessly about his origins, his abilities, and his purpose. Then, just as quickly as he had risen, Azeroth disappeared, leaving the city of Lilith buzzing with rumors.
Now, the arena gates opened once more, and Azeroth emerged, his black cloak and signature mask unmistakable. The crowd, already buzzing with excitement, erupted into a deafening roar at his appearance.
"He's back!"
"It's Azeroth! The Undefeated Masked Warrior!"
"What's he doing here? I thought he was done!"
Azeroth strode onto the arena floor, his presence as commanding as ever. The announcer, clearly caught off guard by his sudden return, scrambled to his feet and amplified his voice.
"Ladies and gentlemen, demons of Lilith! The prodigal warrior returns! The undefeated, the unyielding, the mysterious… Azeroth!"
The crowd's cheers grew louder, but there was also a hint of skepticism. Many remembered Azeroth's earlier battles, but few believed he had the raw power to compete against the stronger demons now vying for dominance in the arena.
As Azeroth reached the center of the arena, the announcer's voice boomed again. "And today, Azeroth faces not just one opponent, but a Gauntlet Challenge! Five of Lilith's finest warriors will test their might against the Undefeated Masked Warrior!"
The crowd erupted in excitement, eager to see if Azeroth could maintain his flawless record against such overwhelming odds.
The first opponent entered the arena—a towering brute of a demon wielding a massive war hammer. Azeroth stood motionless, his crimson eyes glowing faintly beneath the mask. The gong sounded, and the battle began.
The demon charged with a deafening roar, his war hammer swinging down with enough force to shatter the arena floor. But Azeroth moved like a shadow, sidestepping the blow effortlessly.
He raised his hand, and for the first time, the crowd saw it—a faint crimson glow emanating from his palm.
"What is that?" someone whispered.
Before the question could be answered, Azeroth unleashed the Power of Destruction. The energy sphere struck the demon directly, and in an instant, he was gone—reduced to nothing but a memory.
The arena fell silent.
"That… that's the Power of Destruction!" a spectator finally gasped.
"But that's impossible! Only the Beel Clan can wield that power!"
Over the next week, Azeroth fought in the arena daily, obliterating every challenger who dared to face him.
The revelation of his mastery over the Power of Destruction sent shockwaves through Lilith, with many speculating about his true identity. Was he a rogue member of the Beel Clan? A forbidden experiment? Or something else entirely?
His battles became a spectacle, each one more brutal and awe-inspiring than the last. By the end of the week, Azeroth had not only cemented his status as undefeated but had also ascended to Satan-Class, his relentless training and combat experience propelling him to new heights of power.
