When a God of Destruction Was Reincarnated in Tensura:

The day Rimuru and his group arrived back at the Goblin village, the atmosphere was filled with celebration. Goblins, Hobgoblins, and the Ogres alike gathered to welcome them back, cheering as the group approached. Rimuru noted how much the village had expanded in his absence—new homes, fields, and even rudimentary training grounds filled the area. He felt a deep sense of pride in how far they'd come.

Rigurd rushed forward, bowing deeply. "Welcome back, Rimuru-sama! The village has grown as you instructed, and the newcomers have settled well!"

Rimuru smiled. "Good work, Rigurd. I'm proud of everyone here. It looks like things are shaping up nicely."

Rimuru introduced Kaijin and his brothers—Kurobe and Garm—to the crowd, emphasizing their skills in blacksmithing and craftsmanship. The villagers cheered, excited by the addition of such talented individuals. After the introductions and some brief settling in, Rimuru called Kaijin aside and handed him a chunk of refined Magisteel.

"Kaijin, I need you to craft me a sword using this. Something durable, sharp, and versatile."

Kaijin inspected the Magisteel, marveling at its purity. "This is some of the finest Magisteel I've ever seen. You've got it, Rimuru. I'll make you a blade worthy of your strength."

Rimuru's Training with Hakuro Begins

After arranging for Benimaru and Madox to oversee the soldiers' training, Rimuru called Hakuro to the edge of the nearby cave, where they would begin their intensive training. The cave's secluded clearing was surrounded by trees and rocky terrain, offering an ideal environment for focused practice. The sound of the wind rustling through the leaves added an air of calm before the storm.

"Alright, Hakuro," Rimuru said, stretching his slime-like arms. "You're going all out this time, right? No holding back."

Hakuro smirked, his katana gleaming in the sunlight. "Of course, Rimuru-sama. But don't expect me to go easy.

Rimuru chuckled. "We'll see about that. Let's get started."

The first day of training began with Hakuro demonstrating the basics of swordplay, focusing on stance, footwork, and precision. Rimuru, though a fast learner, struggled at first to match Hakuro's refined movements.

"Keep your balance steady," Hakuro instructed, striking at Rimuru with a quick horizontal slash. "Don't let your footing waver, or you'll leave yourself open."

Rimuru blocked the strike, but the force of Hakuro's blow nearly knocked him over. "Geez, Hakuro, you don't pull your punches, do you?" Rimuru grumbled.

"No enemy would, so why should I?" Hakuro replied with a sly grin, launching another flurry of attacks.

Hakuro's Hazy Style Sword Arts

By the second day, Rimuru's progress was evident. He began anticipating Hakuro's strikes and countering them with increasing precision. However, Hakuro decided it was time to up the stakes.

"Rimuru-sama," Hakuro said, stepping back to reset his stance. "I believe you're ready to face my true technique. This is the Hazy Style Sword Arts."

Without another word, Hakuro disappeared from Rimuru's sight, his body moving so fast it seemed to flicker like a mirage. Before Rimuru could react, a sharp breeze grazed his side as Hakuro's katana appeared seemingly out of nowhere.

"What the—?!" Rimuru exclaimed, barely managing to block another strike that came from behind him. Hakuro's movements were fluid, unpredictable, and relentless.

Great Sage's voice echoed in Rimuru's mind. "Analyzing Hakuro's Hazy Style Sword Arts... Adjusting battle stance for optimal counterattacks."

Rimuru grinned. "Thanks, Great Sage. Let's see how long he can keep me on the ropes."

The rest of the day was a blur of strikes, parries, and counters as Rimuru adapted to Hakuro's style. By the end of the second day, Rimuru could track Hakuro's movements, though matching his speed and precision remained a challenge.

The Thousand Blade Moon Style

On the third day, Rimuru felt something click. He combined the techniques he had learned from Hakuro with the combat styles stored in his memory, creating a unique form of swordsmanship. It was time to put it to the test.

"Hakuro," Rimuru said, gripping the wooden sword. "I think I've got something new to show you."

Hakuro raised an eyebrow, intrigued. "Oh? Let's see it, then."

Rimuru took a deep breath and entered a low stance. His aura shifted, becoming calm yet charged with energy. "This is my new style I just created, I call it "The Thousand Blade Moon Style."

The moment Hakuro moved to attack, Rimuru's figure blurred, splitting into multiple afterimages. Blades of energy appeared around him, their silvery glow resembling the soft light of the moon. The swords moved independently, slashing at Hakuro from all angles.

Hakuro's eyes widened as he deflected the incoming strikes. "What incredible precision... Each blade moves as if it has a mind of its own!"

Great Sage's voice guided Rimuru, analyzing Hakuro's movements in real-time and adjusting the blades' trajectories accordingly. "Integrating Hazy Style Sword Arts with multi-directional attack formations. Maintaining unpredictability."

Hakuro's calm demeanor began to falter as he struggled to keep up. The blades danced around him, their movements fluid and erratic. One blade grazed his sleeve, another nicked his shoulder, and before long, Hakuro was completely overwhelmed.

Finally, Rimuru executed the finishing move: a spiraling slash that sent the remaining energy blades converging on Hakuro. The older swordsman dropped his wooden sword and raised his hands in surrender.

"I yield," Hakuro said, a smile of genuine admiration on his face. "Rimuru-sama, your Thousand Blade Moon Style is unlike anything I've ever seen. It's not just powerful—it's art."

Rimuru, panting slightly, reverted to his slime form and chuckled. "Thanks, Hakuro. But I couldn't have done it without your help. Your Hazy Style was the foundation I needed to make this work."

Hakuro bowed deeply. "You honor me, Rimuru-sama. It is a privilege to train someone as talented as you. I look forward to seeing how far you can take this new style."

Rimuru nodded. "I'll keep refining it. But for now, let's call it a day. I think we've earned a break."

The two returned to the village, Hakuro's pride as a swordsman intact and Rimuru's confidence soaring. The Thousand Blade Moon Style would undoubtedly become a cornerstone of Rimuru's strength, a testament to his growth and the bonds he had forged.
