The Rise of a New Demon King

The day started with an unusual intensity as Shiro and Chiyo were called to meet Kenzo at an unfamiliar part of the Kagemoritai headquarters. The corridor was dimly lit, lined with ancient-looking carvings that exuded a strange, almost otherworldly energy. As they reached a large, reinforced door, Kenzo turned to face them.

Kenzo: "Today's training isn't just about strength or teamwork. It's about survival—and understanding your limits."

Shiro raised an eyebrow. "Survival? What are you talking about?"

Chiyo scoffed, resting his spear on his shoulder. "Whatever it is, I'm ready. Bring it on."

Kenzo smirked and placed his hand on the door. "You say that now, but you have no idea what you're walking into."

With a heavy push, the door creaked open, revealing a vast, glowing chamber. The air shimmered as though charged with energy, and the room stretched endlessly in all directions. The sky above was a gradient of shifting colors, and the ground beneath their feet radiated faint warmth.

Shiro: "What is this place?"

Kenzo stepped inside, motioning for them to follow. "This is the Time Chamber. Time flows ten times faster here than in the real world. A single hour outside equals ten hours in here. It was created by an old companion of mine and Akira's, back when the Kagemoritai was just beginning. Its purpose? To forge the strongest fighters imaginable."

Chiyo glanced around, intrigued. "So, what do we do here? Train until we drop?"

Kenzo's smirk widened. "Not exactly."

As Shiro and Chiyo stepped further into the chamber, the door closed behind them with a resounding thud. The atmosphere shifted, the air growing heavier. Both boys exchanged uneasy glances.

Shiro: "Alright, so what's the plan?"

Kenzo turned to face them, his expression suddenly serious. "Attack me. With everything you've got. Your goal is to kill me."

Shiro blinked, stunned. "Kill you? Are you serious?!"

Chiyo frowned. "Is this some kind of joke?"

Kenzo's eyes narrowed, and without warning, he lunged at Shiro. Before Shiro could react, Kenzo's blade sliced through him, and Shiro crumpled to the ground, lifeless. Chiyo froze, his breath catching in his throat.

Chiyo: "What the hell did you just do?!"

Before he could process what had happened, Shiro gasped and bolted upright, his chest heaving as if waking from a nightmare. He stared at his hands, then at Kenzo, shock and fury in his eyes.

Shiro: "What was that?! I was dead!"

Kenzo sheathed his weapon, his gaze cold. "The Time Chamber doesn't just speed up time. It revives anyone who dies within it. That's why we're here. To train without limits, without fear of consequence."

Shiro stood, his fists clenched. "You could've warned me!"

Kenzo's smirk returned. "If I had, you wouldn't have taken it seriously. Now, attack me. Both of you. Show me what you've got."

Chiyo growled, his grip tightening on his spear. "Fine. If that's how it's going to be, then don't hold it against me when I beat you."

Shiro and Chiyo exchanged a glance before nodding. Together, they charged at Kenzo, their weapons gleaming with energy. The chamber erupted into chaos as shadows, light, and dark energy collided with Kenzo's unrelenting strength.

Despite their combined efforts, Kenzo's movements were impossibly fast, his counters devastating. Shiro summoned waves of shadows, attempting to trap Kenzo, while Chiyo launched precise, powerful strikes. But Kenzo evaded and deflected with ease, his expression unreadable.

Kageboshi: "He's toying with you, Shiro. Focus. Don't just react—anticipate!"

Yamitsuki: "Chiyo, don't let your anger cloud your judgment. Your strikes are too predictable."

Kenzo's blade swept through the air, narrowly missing Chiyo but leaving a scorch mark on the ground. He moved with the precision of a predator, always a step ahead.

Kenzo: "Is this all you've got? I expected more."

Frustration boiled over in Shiro. He unleashed a barrage of shadow strikes, pushing his energy to the limit. Radiance gleamed in his hand as he closed the gap between him and Kenzo. But as he swung, Kenzo sidestepped effortlessly, delivering a blow that sent Shiro sprawling.

Chiyo roared, lunging with his spear in a flurry of strikes. For a moment, it seemed he had Kenzo cornered—until Kenzo caught the spear with one hand and twisted it out of Chiyo's grip, forcing him to the ground.

Kenzo: "Pathetic."

The fight continued for hours, each revival bringing Shiro and Chiyo back more frustrated, more determined. But no matter how hard they tried, Kenzo remained untouchable.

Finally, Kenzo raised a hand, signaling the end of the session.

Kenzo: "That's enough for today. You'll meet me here tomorrow at the same time. Be ready to do it all over again."

Shiro and Chiyo collapsed to the ground, their bodies battered and their spirits bruised. Shiro stared at the shifting sky above, his thoughts racing.

Shiro: "How are we supposed to beat him? It's impossible..."

Kageboshi's voice echoed in his mind, calm yet firm. "You're not supposed to beat him. Not yet. Focus on learning, not winning."

Chiyo sat up, wiping blood from his lip. "I'll beat him. One way or another."

Kenzo smirked as he walked toward the chamber's exit. "Good. Use that determination. You'll need it."

Elsewhere

Far from the Kagemoritai headquarters, Akira stood in a darkened alleyway, his presence imposing as ever. Across from him was a figure cloaked in shadow, their face obscured. But as they stepped into the faint light of a streetlamp, Akira's eyes narrowed.

The man smirked, his dark aura pulsing faintly. "My name is Orithius. " He said with a sleek and evil voice. "I heard you met my pupil, Kael, and I'm glad we finally meet, Akira."

Akira's voice was calm, almost cold. "So, you're the one pulling the strings. What do you want?"

Orithius chuckled, his tone dripping with malice. "Want? Oh, Akira, this is far bigger than you or your precious Kagemoritai. You'll see soon enough."

Akira's hand moved toward his weapon, his stance ready. "I've dealt with your kind before. You're nothing new."

Orithius's smirk widened. "And yet, here we are. Tell me, Akira—how far are you willing to go to protect your son?"

The question hung in the air like a blade, cutting through Akira's composure. For a moment, his usually unreadable face betrayed a flicker of vulnerability—a tightening of the jaw, a subtle shift in his stance. His mind raced, weighing the implications of Orithius's words, and the resolve in his eyes hardened like tempered steel. Kael's master laughed as he disappeared into the shadows, his parting words chilling.

"Enjoy your training sessions. They won't prepare them for what's coming."

As silence returned to the alley, Akira tightened his grip on his weapon, his jaw set with determination. The game had only just begun.
