what if Naruto had devil fruits

Chapter 15 1st Great war

The demonic creature summoned by the leaf didn't take its time to  try and destroy the leaf, the mist would watch the fight using the mirror mirror no mi other mist shinobi would attack the leaf from the other side making them be forced to fight each opponents separately,

Weeks earlier a shinobi was strapped to a table, the 6th tails jinchuriki chakra was getting absorbed, the chakra was going into a box. Eventually the chakra gathered was enough for the mist to almost break the box seal, taking the chance they traveled to the leaf using a new ninja with the mira mira no mi.

They then awakened satori taking the appearance of a bird demon attempting to suck uo butsuma into the box, he was strong enough to resists, as the creature is fully formed. Immediately sending a dark black energy towards he leaf butsuma is forced go infront of the attack. Generating a force of chakra which was blue but with water spirals within it along with transforming into his bug hybrid to gain a increase in strength and speed.

The 2 attacks clashed being completely equal, butsuma and the creature would attack 1v1, it was clear butsuma was slowly losing but he was powerful enough to head butt the yokai out of the village. Mito would later join butsuma conjuring dozens of chains which tried to seal away the chakra being but mito wasn't powerful enough.

While mito and butsuma deal with satori, the other hidden leaf shinobis would figth against the 2 or so dozen mist shinobi, each had the initiative and attacked using a surprise. The main fighters the hidden leaf had since alot of their shinobi was spread thin was danzo, torifu Akimichi, koharu, hormura with sakumo being involved at this point he was a jonin being even stronger than ochimaru. 

The hidden leaf had the strength and number advantage but with the mist having a teleported, it was hard to pinpoint where they were targeting. Eventually danzo using a perfect transformation had fooled the enemy team in getting into this alternative dimension, where at that point danzo would kill tons of them before being retreating.

Not wanting anymore casualties the mist remaining shinobi left, it was a hard battle for the leaf but barely anyone died, as they were mostly stalling them targeting valuable areas such as the hospital or the ninja academy. All attempts failed but they were successful,  no one from the village did interfere with mito and butsuma fight.

Satori couldn't be sealed with mitos chains at each point the creature was to strong, butsuma was forced to use his water release: rotation technique many times to counter satori blasts. However when mito used the time tails chakra, her form becomes a yellow shine of gold and beauty now at full power she fought satori by herself defeating the demon.

While she was fighting butsuma had come up with the idea that they need to seal the thing in the box the mist had brought, butsuma would leave the battle to obtain it while mito weakens the creatures with her chains. Her chains touch the creature now in her 9 tails state she was able to ragdoll the creature around, weakening satori only for kurama to speak in mitos mind.

"Mito, the 6th tails saiken is inside that creature".

Mito realised that if she sealed the thing in the box kuramas brother would he sealed alongside it, mito thinks about why the mist would do this. Satori with mitos lost concentration broke out the restrainments, mito sees using her future sight her chains being absorbed by the thing making him even more power, so to avoid this mito would redirect her chains.

Eventually mito is able to form a giant sealing barrier around the box that butsuma had returned with, mito in her KCM mode would perform various handsign. With the help of kuramas chakra she managed to separate the 5th tails from it before sealing it inside the box.

She'd however dropped to her knees exhausted,  butsuma would make sure she's okay, mito looked tired and for the first time in ever her appearance conveyed her age. Butsuma looked at her speaking.
