Chapter 9: "The First New Island"

Danzo's smirk widened as he unleashed his Fireball Jutsu, confident that he had discovered the man's elemental weakness. To confirm his suspicion, the man swiftly dodged the incoming fireball, finally revealing a little about his ability.

Danzo: "Finally dodging? Seems like fire is your weakness!?!"

The man, gritting his teeth in frustration, felt a surge of memories flooding back—a recollection of another technique related to the newfound ability he had acquired. His face contorted as a realization struck him.

Man (shouting): "Nenshokei: Miok Gas!"

A new wave of gas began accumulating, surrounding both Danzo and his remaining Root shinobi. Unfamiliar with this technique, Danzo ordered his team to fall back and utilize Fire-style jutsu. Two of the Root members began weaving hand signs for their jutsu, preparing to counter the impending threat. However, as soon as they released their techniques, an unimaginable explosion rocked the area, consuming all the shinobi caught within it.

Witnessing the devastating outcome, the man, standing at a distance, saw the anger in his eyes subside slightly. Before he could exhale a sigh of relief, he sensed two fireballs hurtling toward him, enveloping him in a fiery embrace.

BOOM

Smoke fills the battlefield and no heads from tail can be distinguished at this moment

after the smoke subsides on both sides of the explosion

we could see two char bodies lying motionlessly making them root shinobi who unleashed their first fireball jutsu and some distance from them stood Danzo and his last Root member 

at this moment anger is visible on Danzo's gloomy face 

he seems to be staring at the distant smoke subsiding and making out the figure of a man kneeling on the ground with blood leaking from the corner of his lips

man coughs up a little blood and shakily stands up again

Again, the man got angry at his powerlessness but before he could lament this fact, a strange energy washed over him again and he felt his physique improving yet again the first time was when he ate that fruit, and now again 

and his shaky body becomes stable again 

he feels amazed over this body's tenacity, he never knew his body was capable of withstanding this highly strenuous battle against a ninja 

he once again firms his resolve to avenge his son and looks towards the perpetrator.

at the same time, Danzo finally had enough of it seals his hand and casts a summoning jutsu and summons Baku

Poof

with smoke a gigantic elephantine chimera appears, It is predominantly dark orange in color except for its trunk, legs, and the markings around its eyes. Its feet are striped — reminiscent of those of a tiger and it also has huge tusks, what looks like a beard, as well as long, sharp claws. It has bandages wrapped around its head and plated armor at the base of its trunk. 

his figure so tall the man feels an ant in front of it and fear starts to creep in but for some unknown reason his brain once again washes over with energy and he feels that the gigantic elephantine chimera doesn't seem too big it's as if I have seen taller figure then this animal. but he's sure he hasn't but he just brushed it off at this moment

Baku looks around spots the tiny figure in front of it then turns to Danzo in an unpleasant mood 

Baku: Why did you summon me? Don't tell me this guy is troubling you so much that you couldn't resist.

Danzo: Don't underestimate that guy, He has killed 7 Root Shinobis with himself

Baku finally gains interest in his opponent and squint towards the tiny figure in front of it and opens his mouth to start sucking it in

the man sees this and smiles and turns into purple gas and flows in his mouth

seeing this 

Danzo shouted in realization: No Baku that guy is a gas and a lethal gas don't suck him in!!

but it was too late man flew straight in his mouth and Baku closed it

and turns to Danzo in Disdain you call me for this weak.... but before he can continue his expression turns twisted and his face becomes purple and he falls with a 

BOOM

Danzo Shouts: Bakuuuu...

but instead of Baku answering a gas emerges from his trunk with a hideous face

and turn towards the last remaining root shinobi and shouts

GASTANET

and another explosion occurs enveloping the last Root.

seeing this Danzo's face turns even ugly than before and before he can do something another earth tremor occurs just like in the morning but with more intensity both parties are stupefied at this sudden occurrence and before the horror of their very eyes another island pops up in distant see it the speed of emerging from water so fast that you can say that if anyone blinks at the moment the island would have stood there like it was their standing there before time immemorial 

Danzo swiftly regains his bearing from shock casts a jutsu and runs towards the distance island to take cover from this abomination of gas.

meanwhile, man sees Danzo running over the sea to the distant island and tries to chase after him but just as his feet touch the water of the sea he feels an incredible amount of weakness wash over him and he limps on the coast and he pulls his feet back up on land and regains his composure finally realizing beside the element of fire the seawater also seems to be his weakness man looks at distant Danzo almost reaching the land and again want to turn into gas and float over to that island but he the strain of battle finally catches up to him and he collapses on the ground.

Giving one last look at the distant island where his enemy seems to have vanished he picks himself up and walks slowly toward the body of his son

Reaching beside his kid, looking at the terror-stricken face son before death he collapses in grieve and kneels and takes his son in his lap crying 

and keeps repeating: I am Sorry, I am Sorry 

he kept weeping beside his son trying to comfort his dead kid or himself only he knew, and finally picked up his son's body to bury him.

Meanwhile 

Danzo finally escapes from that abomination of gas and reaches this new island shore...
