When all might left you to rest your body's adrenaline was still high so you were only temporarily knocked out
Y/N: jeez, that 6th upper moon demon was tough is that really how strong the upper moons are
Y/N: then how come when I fought akaza who was upper moon 3 he wasn't as difficult to fight as this guy
You racked your brain and thought a bit
Y/N: no way.....
Y/N: no way...... so if I'm correct, when I fought akaza he was holding back on me. No way right, no one in the whole world as far as I know could be that strong without going full power
Before you could think more there was a massive shake of the earth and it's blew up the debris surrounding you
It cleared up the space at which all for one and all might were still fighting
You could see all might looked half dead while all for one was still going strong
You realised that resting for a few seconds and refilling your oxygen tank was giving your body a lot of its strength back
You inhaled and gripped your sword as hard as possible with the power you got from the breath
With the intense grip you had on your sword it turned red
Insert red demon slayer sword pic
Y/N: hm? What does this red sword thingy even do
Y/N: (must show how cool I am in battle)
You made this face as you thought about it
Insert stupid grin face
You took a long and deep breath waiting for all for one to grant you an opening
All for one went to all might when his guard was down but they clashed and all might was severely losing
You rushed in using
Y/N: Thunder breathing: thunder clap and flash
You sped past all for one and all might cutting all for ones arm
Y/N: damn what the hells up with your arm,
You damn friendAll for one: it's you, My poor nephew stuck alongside the heroes how about you come and join your uncles side.
Y/N: huuuuuh??!? Like hell I'm your nephew you bastard
Y/N: I'm just here to stop you from killing all might
You heard some noice and you noticed the helicopter above you was recording the fight
You looked towards them and thought
Y/N: you idiots
All for one smiled and aimed his hand at the helicopter then fired a massive fireball at it hoping to burn the crew members and explode the helicopter
All might didn't have enough time nor the ability to stop it
You ran as fast as possible using a sword technique you developed during your training
Improvised flame breathing: 7th form: FLAME RENDERENCE!!!!!
