Multiverse Shenanigans: Raja's Journey

The bustling streets of Tokyo were alive with energy, but my focus was sharp—I needed to find Lady Tamayo. According to my anime knowledge (which, let's be real, is OP), she had to be in the city, and her insight could be key in bringing down Muzan. Lady Tamayo, one of the first demons Muzan created, had long since broken free from his control. If I could earn her trust, maybe we could figure out how to end Muzan's reign.

Garuda, my eagle companion, circled overhead, helping guide me through the crowded streets. After what felt like hours, I spotted her. She stood in a dimly lit alley, accompanied by Yushiro. They both noticed me approaching immediately. Their eyes narrowed, unsure of my intentions.

Quickly realizing they were on guard, I dropped my sword to the ground and sat five feet away, signaling that I wasn't a threat. "Hey there!" I greeted them with a grin, trying to break the tension. "I know what this looks like—random guy with a sword showing up—but I'm here to help. Promise."

Tamayo raised an eyebrow, skeptical. "What is it you want, Slayer?"

"I'm here because we're after the same thing," I said, keeping my tone light but serious. "I know you oppose Muzan. I do, too. And I've got something that can help you break free of any influence he still has on you."

Yushiro stepped forward, visibly protective. "And why should we trust you?"

I smiled confidently. "Because I know things. Things that could help us both. Like how Yoriichi Tsugikuni almost killed Muzan."

Tamayo's eyes flickered with recognition, but she remained silent. I could tell she was intrigued now, so I leaned in a little.

Once I explained the pill I had—a concoction designed to sever Muzan's last bit of control over her—Tamayo hesitated. After a moment, though, she took it. I watched closely as she swallowed, her face tightening briefly before slowly relaxing. It was like watching invisible chains snap free—her entire posture changed, as if a weight had been lifted from her shoulders.

Yushiro, seeing her reaction, cautiously took the pill as well. He glanced at Tamayo, then at me. "I feel… different," he muttered in awe. "Stronger. Clearer."

"Exactly what I was hoping for," I said with a grin. "Now we're talking."

Tamayo studied me more closely. "You mentioned Yoriichi Tsugikuni. What do you know of him?"

"Only what I've gathered," I said. "And what you probably already know. Yoriichi was the strongest Demon Slayer ever, and the only one who ever pushed Muzan to the brink of death."

Tamayo's expression grew solemn. "Yoriichi… yes. I was there, but the story of that battle is unknown to others. Muzan has never been more afraid of anyone than he was of Yoriichi Tsugikuni."

I leaned forward, eager to hear more. "What happened in that battle?"

Tamayo glanced at Yushiro, as if to make sure he was listening too. Then, she began to speak, her voice quiet but intense. "It was centuries ago. Yoriichi Tsugikuni was unlike any swordsman in history. When Muzan first encountered him, he underestimated him, as he had done with every opponent before. But Yoriichi was different. His swordsmanship, his strength—it was beyond anything Muzan had ever faced."

She paused, her gaze distant as if she could still see the battle in her mind. "In their confrontation, Yoriichi dealt blow after blow, cutting Muzan apart. He reduced Muzan to a mass of severed flesh in mere seconds. Muzan's body, which could heal from any wound, was utterly destroyed—except it didn't kill him. Muzan was a creature beyond normal understanding, and even Yoriichi's power couldn't finish him outright."

"How did Muzan survive that?" I asked, already feeling the frustration of a near victory slipping away.

Tamayo shook her head slowly. "In his desperation, Muzan scattered himself—dividing his body into hundreds of tiny pieces and fleeing in every direction. Yoriichi, powerful as he was, couldn't track all the pieces at once. It was the first time in history that Muzan had ever fled from a fight."

I let out a low whistle, impressed but frustrated. "So he almost had him—just not quite enough."

Tamayo nodded solemnly. "Yoriichi came closer than anyone ever has. But Muzan survived, and his fear of Yoriichi remained. It's one of the reasons Muzan has hidden in the shadows for so long. Yoriichi left him scarred, not physically, but mentally. He knew that Yoriichi's strength was something that could one day destroy him."

Yushiro added, "And ever since, we have been searching for a way to finish what Yoriichi started."

I leaned back, digesting the information. "Well, maybe we have a way now," I said, determined. "With what you know about demons and what I've discovered, we might be able to finally take Muzan down."

Enter: The Kamado Family

Armed with this new knowledge, I knew the next step was to find the Kamado family. According to the intel I had, they held the key to unlocking a powerful technique. The Fire Festival Dance, a tradition passed down in their family, might be the missing link we needed to face Muzan.

When I arrived at the Kamado household, it was like stepping into a peaceful winter wonderland—snow-covered trees, smoke rising from a small chimney, and the soft glow of lanterns lighting the way. I knocked, and the door was opened by Kie Kamado, a kind and gentle woman. Her warm smile and welcoming aura made me feel at ease right away.

"Good evening," I said politely. "I've come to ask about the Fire Festival Dance your family has been performing for generations."

Kie's smile faded slightly, replaced by a look of sorrow. "My late husband used to perform the dance," she said quietly. "But since his passing, no one here knows how to do it."

As we talked, Tanjirō Kamado appeared, carrying a basket of firewood. His eyes were cautious, especially when they landed on the sword by my side. "Who are you?" he asked, clearly trying to gauge if I was a threat.

"Just a traveler," I said with a small smile, trying to ease the tension. "I'm here to learn about a dance your family is known for."

Tanjirō's suspicion lessened a bit, though he still eyed my sword with curiosity. "Are you a Demon Slayer?" he asked, his tone more curious now.

"You could say that," I replied, nodding. I let him inspect my sword, and he carefully examined it with wide-eyed wonder, running his hand over the hilt. There was something about him—something strong yet gentle, like a simmering flame waiting to ignite.

Eventually, I handed Kie a bag of coins, enough to support the family for a year. "For your trouble," I said, smiling. "I appreciate you sharing your family's history with me."

Kie was shocked. "This is… too much," she said, hesitating.

"I insist," I told her. "You've been a big help."

Kie, gracious as ever, invited me to stay for dinner. I accepted, and while she cooked, I entertained the younger Kamado siblings with small tricks and stories. Their laughter filled the house, and even Tanjirō, who had been so serious, couldn't help but smile. The Kamado family was warm, inviting—and something about them made me want to protect them even more.

After dinner, with the children asleep and only Tanjirō, Kie, and I still awake, the conversation turned serious. They asked me about my profession, and I explained as much as I could—how I was fighting against Muzan and the demons.

You know about the Sun Breathing?" he asked quietly.

I nodded. "I do. And I think you can learn it, Tanjirō. You have the fire in you."

Both Tanjirō and Kie stared at me, wide-eyed.

"I'll train you for one year," I offered. "And after that, you'll be ready to protect your family and face whatever comes. All I ask is for your trust—and your willingness to fight."

The next morning, Tanjirō agreed. I gave him the 15% pill, and from that day forward, he trained with me diligently. Supplies came regularly from the Demon Slayer Corps, and with a strict diet and rigorous training, Tanjirō's body grew stronger, his breathing technique more refined.

One Year Later

Training Tanjirō had been an incredible experience. Over time, he grew stronger, honing his breathing techniques under my guidance. The Kamado family had become like a second home to me, and supplies from the Demon Slayer Corps kept us going.

But I knew that Muzan was drawing closer. The day would soon come when Muzan himself would arrive at the Kamado household. When that day came, I had to be ready.

The Kamado family had become like my second home, but the time had come. I knew Muzan would soon arrive to finish what he started. I sent the family to town the day before, with Gyomei and Tengen secretly guarding them from the shadows.

I made sure the Kamado family was safely in town and prepared for the confrontation. As I stood in their now-empty house, waiting for Muzan's arrival, my determination only grew. I would finish what Yoriichi had started all those centuries ago.

That night, as I stood in the Kamado house, disguised by the power of mystique, I waited. Muzan's presence was unmistakable as he approached, his footsteps echoing in the cold night.

The door creaked open, and there he was—the great Demon King himself. His eyes met mine, and in that split second, realization dawned.

He bolted. Without a word, without so much as a flicker of bravado, Muzan turned and fled into the night, his cowardice palpable.

"Well, that went better than expected," I muttered, chuckling to myself.

The Great Demon King had met his match, and he was terrified.
