A New Journey: The Elemental Hashira

The Final Showdown

"It's Nezuko" I said. I run over to her and she instantly hugs me while she is crying. She was very upset seeing that her brother just died right in front of her. "Hey I have an idea Nezuko!" She looked up at me and tilted her head to the side. "Come along with Me and Giyuu. We're going to Destroy Muzan Kibutsuji, the one who turned the both of you into demons. What do you say?" I ask her.

"mmMM!" Nezuko shook her head yes. "We'll come along with you Tatsuya" I heard a familiar voice behind me and I turned to see who it was. Behind me was the Stone Hashira: Gyomei, The Wind Hashira: Sanemi along with Giyuu. "Really? You guys are going to tag along?" I asked them. "Of course. That's the job of a hashira is it not?" Giyuu replied. I smiled and agreed with him.

The sun starts to rise so I put Nezuko back into her box and start carrying it on my back like Tanjiro used to do. Alright let's head ou-" Suddenly we were all teleported into some sort of Castle like structure with only 2 paths out of the room. "W-What the hell just happened!?" I asked. "It seems like we were teleported into the Infinity castle. I turn to Gyomei. "What's the Inifinity Castle?" I ask. "It's an alternate dimension where Muzan Kibutsuji lives. Not even the highest among the upper moons are allowed here without his permission" Gyomei explained.

"It seems like he wanted us to find him. We should be careful there could be many traps here" Giyuu said. "Let's split up into teams, Giyuu and I on one team and Sanemi and Gyomei on the other" I suggested. "Very well then. Let's go Sanemi" Gyomei said. Gyomei and Sanemi took 1 path and We took the other one. "You can come out now Nezuko" Nezuko hops out of the box.

I turn to Giyuu as we're walking down the hall. "Don't you think it's strange that he would want us to find him? I mean, he ran away from us JUST to encounter us right after running away?" I say. "Hmm you give a valid point on this. Although I just think he wants to fight us on his territory. Someplace he knows like the back of his hand" Giyuu suggests. "Yeah you could be right about that. It makes sense at least. He's not usually the one to run away if he's prepared for a fight" I Say.

"He probably ran away after seeing you. You did defeat Upper Moon 1 by yourself after all. That's a very big feat on its own. He was probably nervous that you would be able to defeat him there, so he had to make a strategic retreat. That's only a theory of course" Giyuu responds. As we're walking, we see the end of the tunnel and come across Muzan Standing in the middle of the room. "So we were the unlucky ones Huh?" Giyuu said.

"Nezuko, stay back for now. You're not ready for this fight" I say to her. Before I dash towards Muzan, Nezuko grabs the sleeve of my shirt while making a sad face. "Gaaah. Fine you can fight with us. The more the merrier I suppose" I sigh. Nezuko instantly seems happier as she gets into a fighting position. I press the button on my sword making the other blade with the chain connecting the two of them drop down into my other hand. Then I Activated my Demon slayer Mark. "Are you ready Giyuu? Nezuko?" I say as I look at the both of them.

Giyuu has his demon slayer mark activated and Nezuko has her adult form on. "mmMM!" Nezuko responds. "Yes" Giyuu responds. "Right. LETS DO THIS!" I shout. "Sound Breathing, and now Thunder Breathing" one sword starts glowing firework colors and my other blade is surrounded with Lightning. I dash towards Muzan swinging my sword sideways. "SPARKING SOUND!" I cut Muzan in half but he instantly regenerates. He then swiped his hand upwards slicing my right leg open.

"Damit!" I say. "Water breathing 9th Form: Splashing water flow: Turbulent" Giyuu suddenly releases a bunch of quick slashes at Muzans neck. After a few hits, Muzan suddenly starts to dodge them all. But before he could do anything, Nezuko kicked him in the stomach making him go flying, crashing into the wall. I waste no time and dash towards him. "NOW! FLAME BREATHING!" Both Swords get surrounded with flames as I put them together and raise them above my head. "FLAME TIGER!"
