Uppermoon 3: Akaza

"Stop the bleeding" Rengoku said to Tanjiro
-Tanjiro stopped it bleeding I heard something in the distance I got in my fighting stance something jumps to the ground me and Rengoku stared at the figures eyes they said Upper 3 he tried to hit Tanjiro-
|Flame breathing, Second form: Rising scorching sun!| Rengoku cuts Akaza's arm through the middle-
"what a fine sword you two must be hashiras huh I can tell just by looking at you two" Upper 3 said
"What are your names" Upper 3 asked excitedly
" I am the flame hashira Kyojuro Rengoku" Rengoku said unfazed
"I am the fox hashira Y/N Ogami" I said calmly with a smile
"I am Akaza"
"Kyojuro Y/N you should both become demons you'll become much stronger and you could become a twelve kizuki" Akaza asked/explained
-I stepped in front of Rengoku-
"We will never become demons no matter the twisted reasons you give" I responded annoyed
"Growing old, passing away that is what makes the human life beautiful" Rengoku said
"I see I guess I'll just to kill you then" Akaza responded sadly
-me and Rengouku watched as he crushed his foot into the ground while preforming a demon art technique. Rengoku charged at full speed and just like that they were in a fight I looked at Tanjiro and went over to him quickly I grabbed some bandages out-
"Can you lift his shirt up inosuke" I asked politely
-inosuke lifted Tanjiros shirt up and I started to bandage his stab wound-
"Don't move you'll open the wound up again" I said to Tanjiro
-I ran to help Rengoku he was fighting Akaza he backed away for a second to catch his breath because Akaza was forcing him to use his breathing styles constantly I stepped in his place-
"What a shame a hashira has to catch their breath so Y/N I wonder what your breathing style is " Akaza said
mockingly/interested
- Akaza blinked and i was already in front of him cutting him in half-
"That's impressive but not enough" Akaza said shocked
-he regenerated quickly- " I can see you trained for years your near perfection but you will never reach it" Akaza told
-Akaza started sending demon art punches flying in my direction- |Fox Breathing, Second form: Fluffed fur| Akaza's thoughts [Mist appeared?]
-I watched Akaza fall to the ground coughing I smiled-
"Poison I wasn't expecting that" Akaza coughed
"I did not know you used Wisteria as well Y/N" Rengoku said surprised
" I've been making my poison more potent with the help of Shinobu but it won't last long it's Upper-moon 3 after all" I replied getting read to fight again
" I must say you have an interesting breathing style" Akaza said before doing another technique
|-Me and Rengoku have been fighting for awhile now and I know Rengoku is going to use his ninth form and it will leave him exposed for Akaza to attack I got to think here oh I know-|
" Fox Breathing, Seventh Form: Fox Stealth" I said smirking as more of me appeared
" What is this" Akaza said before punching one of the clones
Rengoku's Thoughts: I'll have to inflict as much damage I can in an instant
" I will see my duty fulfilled I am the Flame Hashira Kyojuro Rengoku!" Rengoku Yelled
" Flame breathing Esoteric Arc, Ninth Form: Rengoku," Rengoku roared before launching forward at Akaza
" Technique Develop,  Destructive Death: Annihilation type" Akaza said Excitedly
|A dragon of flame turned into a spiral of flame and I watched as the flames and dust disappeared I widened my eyes slightly but I didn't cry or feel sad when the dust was gone it revealed Rengoku with Akaza's hand pierced through his stomach I heard Tanjiro yell|
" Rengoku-San!" Tanjiro yelled in pain
| I got up and quickly ran to kill Akaza while the sun started rising Rengoku held Akaza there for as long as he could I was about to cut Akaza from behind but he jumped in the air regenerated and ran into the trees I turned to Rengoku|
" I'm sorry I couldn't save you Rengoku" I said unfazed as I sat down infront of him
" It is not your fault you had great swordsmanship I believe you will soar to greater heights I ask you protect Tanjiro, Zenitsu and Inosuke for me" Rengoku said
|while I got up and walked to the train to check on passengers Tanjiro walked over to Rengoku so I assumed they were having their final chat I saw Rengoku fall to the ground and I could hear Tanjiro, Zenitsu and inosuke crying loudly as the kakushi came I could only assume that the Hashiras and the master crows told them Rengoku has passed I went to the butterfly estate with the squad as it was my only option|
(My brain is officially dead anyway that was also short so I guess unless my brain remembers the anime or if I come up with ideas then the other chapter will unfortunately be the same as well but at least I'm trying personally i think I'm doing decent for my first story also just letting you know I'm going to take my time and think about what to write in the entertainment district arc so this will be it for now)
