Swish…
Clang…
Muku swings his arm and deflects a pair of senbons. The goat-masked elder launches another pair of hidden weapons, but Muku easily deflects them with his bare hands.
"It's payback time! You took everything from me. Now it's my turn to return the favor."
Whoosh…
Muku disappears from his place and reappears behind the goat-masked elder.
Stab…
He stabs his hand through the goat-masked elder's chest and rips out his heart.
Guffaw…
The goat-masked elder pukes out a mouthful of blood. Her eyes widen and her lifeless body falls to the ground.
Kachik…
Muku clenches his fist and squeezes the heart into a bloody paste. He turns towards the rest of the animal-masked elders.
The ram-masked elder waves his sleeve and releases a volley of deadly abyssal snakes from them.
Muku opens his mouth to an unnatural degree.
REEEE…
He releases an extremely loud screeching sound from his vocal cords and fires a powerful barrage of black feather-like needles. The deafening noise tears through the surface of the ground and blows away the volley of snakes into smoke.
The feathers continue their momentum and pierce multiple holes through the ram-masked elder like a beehive. Chunks of flesh and blood splash on the floor to create a gruesome sight. Many prisoners and guards with weak personalities puke out their food at the gross sight.
Crack…
Muku's neck rotates at an unnatural angle and turns normal. He closes his mouth and turns towards the remaining two elders.
The bull-masked elder takes out a pair of metallic machetes from his back while the monkey-masked elder takes out a kusarigama from his clothes.
The monkey-masked elder spins the chain of kusarigama and attacks him with kama at the end of the metallic chain. While the bull-masked elder grinds the two blades against each other and generates a spark of purple fire.
He dashes towards Muku while dragging the burning blade against the ground.
Whoosh…
He jumps into the sky and spins in mid-air to perform a devastating blow.
Whoosh… Bang…
Muku swiftly dodges the strike. The powerful impact of the blades creates a crater on the ground. A pillar of purple fire rises from the ground.
Sling…
The metallic chain of the kusarigama wraps around Muku's right leg. The monkey-masked elder tugs it with force to throw off Muku's balance.
The bull-masked elder uses this opportunity to close the gap and swing the dual machete toward Muku's neck and heart.
Heh!
A smirk appears on Muku's face.
Bang…
Muku's bare fingers break through the metallic machete and stab through the bull-masked elder's heart. He rips apart the latter's heart and tosses his dead body toward the Box of Ultimate Bliss.
Weng…
The eyes of the demonic mask glow with an eerie hue. A powerful attractive force consumes the latter's body as it disappears within the abyss of the box.
The box also pulls the corpse of the other two elders within itself.
"It can't be!"
The eyes of the monkey-masked elder widen to the extreme.
Bzzt… Crackle…
Muku grabs the chain of the Kusarigama and tugs it towards himself to pull the monkey-masked elder.
Bam…
He grabs the latter's face and lifts him in the air.
Bang…
Muku smashes him on the ground, shattering his mask in the process. Blood leaks from the eyes, nose, ears, and mouth of the elders. The elder's eyes roll to the back of his forehead and he loses consciousness.
Muku picks him from the ground.
Bang…
Once again, he smashes his face on the ground.
Bang… Bang…
He repeats the process until the skull of the elder is cracked open and his brain matter splatters on the floor.
Swoosh…
He tosses the dead body of the elder toward the demonic mask. The demonic mask consumes the body in a crimson light.
HAHAHA…
Muku presses his blood-stained hand against his face and burst out in a peal of hysterical laughter.
KUHAHAHA…
"Mu… Muku!"
Tears flow from Ryūzetsu's eyes as she stares at the Muku.
"Huh!"
Muku pauses and turns his attention toward her. Ryūzetsu resists the miasma of the box and slowly stands up.
She glares into Muku's eyes.
"YOU… You aren't the Muku I know!" Ryūzetsu removes her bandanna to reveal her long, flowing, white hair.
"What happened to the Muku I considered my best friend?" Her pure amethyst eyes pierce through Muku's soul.
"You are…"
Thump…
An invisible pulse of negative chakra flickers through Muku's body.
"Muku! Don't lose your soul! Return to the Muku you were before the box took you!" She clenches the bandanna as tears flow from her eyes.
THUMP…
Another pulse of negative chakra flickers through his body. Muku's pupil darkens and a crimson glow flashes through them.
ARGH…
Muku clenches his forehead and falls to his knees.
ARGH…
He releases an agonizing scream. The dark miasma in the surroundings gathers above him and drills into his body like a funnel.
"MUKU!"
The miserable screams of Muku pang at Ryūzetsu's heart.
"I will save you, Muku!"
He infuses chakra and resists the pain of the Celestial prison seal to break free from the influence of the miasma.
"No, you can't!"
Maroi grabs her hand at the last moment and shakes his head.
"That person is no longer the Muku you used to know. In his current state, he is a demon!"
He points towards the massive apparition of a winged demon created by the foul miasma of negative chakra above Muku.
Grrr…
Suddenly, Muku's eyes turn red. Saliva drips from his mouth.
Twitch… crack… crackle…
The muscles in his body squirm unnaturally. His bones twist and turn while his flesh writhes throughout his body.
The giant apparition of the winged demon drills into Muku's back and his body suddenly inflate to almost five times in volume.
A massive surge of crimson-red negative chakra envelops Muku's body.
Argh… AAAHHH…
Massive claws sprout from Muku's hands. Gigantic black wings grow out of Muku's back as he leans on the ground in pain. A black feather covers his body and multiple bony protrusion erupts from his flesh. The density of the miasma rises sharply and almost turns pitch black.
Ryūzetsu, Sasuke, Maroi, the guards, and the prisoner stares at Muku's transformation in horror.
Thum… thum…
Heavy footsteps echo in the surroundings as a gigantic, headless monster with massive wings walks out of the pitch-black miasma. The entirety of the monster's body is covered with black feathers. Four long, elongated bony tusk protrudes from the corner of the mouth of the giant monster. The giant monster has a long, thin tail, and its hands and feet are clawed and sickly thin to the point where it almost looks like almost bone-like with skin attached.
The giant monster flaps its wings and rises in the air.
SCREEE…
It releases a powerful scream that terrorizes everyone's heart. The giant monster lifts its massive hand and swipes them toward the prisoner.
SWISH…
With just a simple swipe of its hands, it releases a powerful barrage of wind blades that slices through the bodies of the prisoners.
"RUN!"
The prisoners scream in horror and furiously attempt to escape from the grasp of the demon. The blood and flesh of the dead prisoners are sucked inside the mouth of the demonic mask with a powerful, attractive force.
Weng…
The mouth glows with a crimson hue and absorbs the sacrifices offered by the giant monster. The giant monster rampages in the surroundings and reaps the life of prisoners and guards alike.
"This monster!"
Maroi and the other spies are fear-stricken by the action of the monster.
"I have never seen something like this in my entire life!"
Maroi gulps his saliva and whispers to not attract the attention of the monster.
"I never knew I was dealing with such a monster." The vile chakra of the monster sends a shiver across his body.
"These Kusa Fruit faction members are a bunch of lunatics to release such a demon in the shinobi world."
He grits his teeth and softly prays in his heart.
'I just hope that the reinforcements are quick enough to spot my signal and make their move. If they aren't then I am afraid today will be the day I bade farewell to this world.'
At a far-off distance in the sea,
A fleet of ships rapidly sails in the direction of the island.
