3rd Person POV Again Yet Again

Shadow emerges, before it transitions into Y/n's sword that engraved with the words "Destroyer of Demons" in kanji which he received when he reached the hashira rank. the view changes again to an individual, who's limbs are flying everywhere.

Well that's when our Tsugi noticed that the demon's head was not completely decapitated. yet also, both arms and legs was everywhere. leaving the body and the head to fall to the ground.

"Im-...possible..." The demon grunts as Tsugi strucks him with a wisteria-poisoned knife. "You won't be able to move nor regenerate now." He told, before kneeing one leg next to him.

"...you have massacred seventy-six innocent lives, wounded thirty-two people and you landed a total of three bullets to a little girl. You said you want your revenge. what did I ever do to you?" The pillar questioned with a concerned tone.

"Well I figured this out for you.. almost two centuries ago, I met with your ancestor for the very first time. for my part, I have finally discovered ways to become a stronger demon slayer." The demon told.

"You're a demon slayer?" the pillar was in disbelief. he didn't expect a slayer would turn into such monster. "I was a demon slayer. I used a technique your ancestors used to become much stronger.

more stronger than people could've imagined from me." He states, "Wait wha--" the pillar flinched, "I began to practice constant breathing every morning, noon, and evening." The demon interrupted. "Thank kami..." Tsugi sighs.

"What's a kami?" The demon confused. "Basically god." He answers. "BUT I'M STILL HERE!" It yells. "..."
Y/n stares at him.

"Urgh. after I evacuated the people from demons alone, your ancestor showed up. and saved one last person that was trapped. and then the crowd went 'wheee!! he saved us! bla, bla, bla..." The demon told.

"I saved that village, I should've been the one who get the praise, THEY SHOULD'VE PRAISED ME!!" It shouts.

"He stole my moment. I admired him! and he humiliated me." With the yelling continues, a crowd of citizens was surrounding them, but other demon slayers told them to evacuate. "Only a sociopath react to something so small with that kind of rage." Tsugi stands up.

"What you call rage.. I call commitme--" before he could finish,
Y/n had cut his head in one slash and flicks off the upper ranks blood. the pillar sighs, as he walks up to Silv who's body is covered with blood. he then picked her up, and carried her out from the burning capital.

Later on...

"Oi... don't tell me... he survived? this fight?" Sanemi Shinazugawa stands and widened his eyes. "he did. he didn't lose a limb. he didn't receive any serious wounds..." Giyu and Sanemi watched the sun pillar lays Silv down, the both of them was ultimately left in shock.

"How flamboyant. he defeated an Upper Moon using my move? i'm impressed!!" Tengen joins and was amazed. "I thought I would fight it... WHY WON'T THESE UPPERMOONS JUST COME ON TO ME!" Sanemi was pissed.

"Okay, that wasn't supposed to sound weird but--"

"Shut up, Giyu."

"Right. let's just help them."

Though they congratulates him for beating an upper moon, Sanemi still condemns the Sun Hashira for causing too much damage to the weakest of the upper ranked demons. "Seven, huh? the new AND weakest upper rank. the 'seven' thing aside, you defeated an upper rank. congratulations."

Sanemi, being sarcastic. "It's seven though... otherwise, I'll give you my compliment." The wind pillar states.

"...No, I don't need a compliment from you. In the end of the day, you are right, Shinazugawa-san. I may have defeated an upper rank. but I still am the weakest hashira here..." Y/n rests his head on a rubble, before holding Silv's hand as the Kakushi was on their way to their location.

"That's enough, Shinazugawa-kun. at least we get to see the flamboyant blood spray he did on that demon. also, who is that? your new girlfriend? how about Kocho, though? Is she going to be okay with that?" Tengen goes out and asked some weird questions.

"A-alright! alright! one at a time... first off, she is not. and she's a friend. second of all, why would you bring up Shinobu? It's not like I am interested in her." The sun pillar crossed his arms. "I think the answer's pretty obvious." Giyu said.

"This day can't possibly get any worse..." The sun pillar closes his eyes for a few seconds, aware that the sun is nearly rising.

Unexpectedly, a crow raced up infront of the hashiras and told them some information that made the pillars flinched. "Caw! caw! Em-bashira Rengoku Kyojuro is in trouble and is now dying fighting with an upper rank three.

!

"Uppermoon 3?!" Tengen mentions."TELL US HIS LOCATION!" Sanemi yelled up, while Tomioka just listens with a surprised face. Y/n wakes up having troubled with the noise their giving off. he listens carefully on what they are talking about and piece it in together.

"Kyojuro... Is in trouble?!" The screen moves to the kasugai crow. "Caw! It's in the middle of a train way near here. Caw!" It transitions into the sun pillar. his will of fire then exploded as he speeds off to a certain location.

"Tch, atleast wait for us!!" Sanemi follows him, then Tomioka. whilst Tengen just stood there, surprised. "That was... what was that? was that Tsugi?!" The sound pillar was surprised on how fast his burst speed is, considering that Tengen himself knew that he was faster than any of the other pillars.

Tsugikuni Y/n's POV

"Come on! Faster, dammit!" I thought out loud, before reaching the right momentum to speed up. before I got it, my left arm accidentally hit a tree branch. "Arkh! GOD! DAMN!" Of course, hitting a branch with that much speed was quite brutal.
I stopped and I noticed that there was a cut. I can even feel my humerus cracking after hitting it.

"Dammit! Dammit! Dammit!" I yelled out, getting more than that of exhaustion. I noticed that Sanemi, Giyu, and Tengen was approaching. The wind pillar noticed and picked me up by the right arm and continues to speed off to the location.

"Thank Gotouge. you grabbed my right arm..." I sighed in relieve, while getting dragged. "Fool! You just slowed us down!" Sanemi yelled.

Then, he runs at full speed. the vibrations in my hands, the taste of blood on my mouth, the sound of my heart beating on my ears was gone. It feels like I'm being pushed by some kind of wind. after a long straight thinking, I had an idea.

"Shinazugawa-san! launch me to the air! I know that you'll hesitate, bu--" all of a sudden, he hurled me to the air without hesitation.
"Right. Now... now draw your sword and hit mine!" I shouted, while unsheathing my blade.

"What?! What is this kid planning? argh! screw it all!!" Sanemi leaps off the ground, unsheath his sword, and hit my blade. In that split second, the both of us noticed our clashed nichirin blades turning into crimson red blades.

After I was catapulted, I saw Sanemi having a green colored wind mill-like mark on his cheek. but then dissappeared in a second. "What?" I heard Sanemi spoke. I started to look around and finally saw some smoke. "Finally. I'm coming, Rengoku-san.

Kamado Tanjiro's POV

"OUT OF MY WAY!!!" A demon voice was heard. an Upper Rank 3, Akaza. "why would an upper rank show up right now?! If only I was stronger... Rengoku-san wouldn't suffered a wound like that!" I knew that my only option was to watch. since I can't move and it'll cause my wound to open if i did.

I watched as Rengoku-san's blade moves deeper into Akaza's neck, now reaching its center. "Move, Inosuke!! Move your body for Rengoku's sake!!" Worried, I yelled out to my best buddy and, just as the boar-headed Demon Slayer readies his Beast Breathing, Akaza manages to pull himself away from him.

3rd Person POV

However, the scene was witnessed by Tsugi, moments too late to save Kyojuro. Y/n was displeased by this situation. He was overwhelmed by anger until he oversweat. his heart really feels is like about to shatter.

Kyojuro Rengoku, who's literally has a hole on his stomach, stands up, grits his teeth, and made his stance he just used. "I can't believe it... he's using that move again... after that hole on his gut?!" Tanjiro was nearly shocked.

"Y/n... Y/n and I... we will defeat you!!" Kyojuro's tremendous fighting spirit explodes yet again after seeing his student. the sun pillar shivered, amazed by his sensei.

"I'm pissed now. I don't want to ask more questions again. you really are amazing." Akaza told him, not aware of Y/n behind him, who does not have any fighting spirit at all.

"This air-tight stance.. I can copy it. Rengoku!! AFTER YOU!" Y/n sat his foot, set his heart ablaze, and changed his way of breath. "T-this feeling... he changed his style to copy weird eyebrow's move!!" Even Inosuke was impressed.

That's when Akaza flinches, sensing some massive fighting spirit. now aware of Y/n, he sets up his footing and readies his stance.
"I AM THE SUN HASHIRA!"
"NINTH FORM, RENGOKU!!" Both of the pillars sync together. Akaza was worried. the sun is rising and two pillars is surrounding him.

"They're idiots. unless I held back, I'll just jump out and they'll end up killing each other." Akaza predicted, running to the forest, and avoiding the sun.

but unexpectedly, three pillars that was behind Y/n finally arrives. "We won't let you get away!" Tengen states, pulling both his dual massive Nichirin Cleavers.

"Finally... I've encountered an uppermoon..." Sanemi has a crazed face. while Giyu is helping civillians that was still stuck on the train. after, he goes back and stands before the upper rank.

"I wonder how this will turn out." Giyu draws his sword. "The sun's coming up. there are five hashiras around me... I have to get away... I have to get away!" Akaza has a panicked face, returning to Y/n and Kyojuro's attack.

The master and the student brings their sword into flames, before dashing forward at high speeds.

With Akaza on range, their attack took the form of a flaming dragon that envelopes the breath users as they are charging towards the upper rank. the scene continues in slow motion.


25 meters......

10 meters.......

5  meters......

A meter.....

An inch...

"What?" The blade did reached Akaza, but..

...

...

...

The sounds of clashing swords ringed them in their ears. the impact was so destructive that their blade was split into two pieces.

• Tsugikuni, Y/n. He can switch two breathing styles without any efforts! anymore than two, though, could cause lung failure.

"Be careful out there!!" A soft voice said.
