The last thing you heard was:
Sasuke: Y/N!!!!!
You'd passed out on the floor while sasuke was still fighting akaza there was nothing you could do and since you passed out all of your clones would vanish in a few minutes
*SPOILERS ARE STARTING FROM HERE PN SO IF YOU DONT WANT TO BE SPOILED FOR DEMON SLAYER YOU WONT BE ABLE TO READ FOR A WHILE UNLESS YOU SEE THE MANGA OR WAIT FOR THE ANIME*
(Back to the battle)
Sasuke was in front of your body basically protecting it from any attacks he tried to use his sharingans abilities as much as he could but his eyes were starting to get tired until akaza stopped his attacks to say something
Akaza: it's obvious that you two are too weak to fight me so I will finish you both here starting with that H/C boy!!!
Akaza sprinted of the ground toward you and was about to destroy your head with a punch but before he could...
???: Flame breathing second form: rising scorching sun!!!
Rengoku jumped above you and sliced akaza's arm right before it reached your head the shock of rengoku's and akaza's presences woke you up from being passed outY/N: R-RENGOKU!!! WHAT ARE YOU DOING HERE!!!
Rengoku: I'm here to save my student from a demon ubayashi orders the closest person to the camp to come here and that's why I'm here
Y/N: this akaza demon is really strong. Nghhh. My wounds hurt even more I don't know if it'll make a difference but let me and Sasuke help you, please!
Rengoku: Now Now. I am your teacher and a demon slayer hashira it would be shameful if I weren't able to take down a demon by myself
Y/N: b-but!!!
Rengoku: don't worry about me besides your classmates need help you need to focus on them not me!!!
You sent out the remains of your elemental clones and they all separated to go and help your classmates
Y/N: now all of you go and help my classmates!!!
Clones: ALL RIGHT!!!!
Rengoku got back to fighting akaza and it looked like from your POV that the fight would last about five minutes, and it was almost morning you managed to lift yourself up from your stomach onto your knees but when you sat up rengoku had sent a massive wave of fire towards akaza. And he got a direct hit in when the dust cleared from the massive attack akaza was without much damage and proceeded to rush into a close combat battle with rengoku.
