Last Boss

Shinno in the control room looked incredulously at the massive Earth Wall that came out of nowhere before he fired the main cannon.

He didn't think Konoha would be prepared enough to make such a wall in time; especially with the chaos that Orochimaru and Otogakure's forces distracting them. He assumed a group of people had worked together to make it.

"Hmph. I underestimated them…"

Shinno looked at Reibi behind him - floating in a giant cocoon connected to the walls of the main chamber - constantly being sucked for its chakra. It was shriveled half the size of its original from being squeezed out of chakra used to power the cannon just now. A cry as if like that of an infant was constantly echoing from the snake-like creature.

"So noisy! Just get back here!"

With a hand wave, seals around Shinno's torso lit up - Reibi turned into particles of dark chakra and absorbed into Shinno's body.

He took a deep breath, stretching his muscles and feeling the dark power circulating inside of his chakra network overflowing as purple from his skin. He let out a maniacal laugh, ready to slaughter the incoming Konoha shinobi.

"With this chakra and my regeneration technique, I can use the 8 Gates until the Gates of Death without any worry. Nnhahaha!"

Shinno thought to himself how he was already a godlike being. He moved and pressed a button on the console, activating the microphone to send a message for everyone on board to prepare to receive guests.

"Everyone. Ready for battle! From this day onward, we, the Land of the Sky will regain its glory! Nnhahahah!"

***

The platoon of Konoha Shinobi met with the assault of Sky Shinobi from the sky as they approached.

Tch. Tsuyu spat the sound seeing the approaching platoons of shinobi with wings. They had aerial advantage, but it was clear their technology was more like an aeroplane, and could not make sharp and flexible maneuvers.

"Sai, you control your bird. Leave the offensive to me."

"Understood."

Just then, the black and white living bird painting rushed towards the sky shinobi at a fast speed. Seeing the approaching bird, they take out their chakra guns and fired openly at them.

Sai maneuvered the bird with skill, gliding at sharp angles to dodge with ease. Sai maneuver the bird up - over-taking the latitude by few meters above the platoons.

As the sky shinobi's look up - multiple humanoid figure dropped down from the bird in free-fall.

As their eyes focused, they realised it was clones! Their blue eyes were locking onto their target, using chakra expulsion from the tenketsu to shift their positions and launched themselves. Even while falling, Tsuyu's shadow clones had a clear goal.

To kill!

Each of the shadow clones threw a kunai with explosive tags attached to them. The chaos cause one of the sky shinobi to lose control and collide with another - killing both of them at the same time in a bang.

One of the shadow clones managed to drop right onto one of the shinobi's backs. A grin covering half of her face looked at him as if he's looking at her prey.

"Ahhh! Let go! Let go!" He was panicking as he was being held in a chokehold from behind.

"Hnn~" the clone's devilish chuckle caused panic and fear of death to run deep into his spine as he struggled and spun in the air to get her off.

"Let go!"

The clone's body overflowed with unstable, overloaded chakra. Its eyes glowing in a cold blue light. The cries of the shinobi in the sky did nothing to stop her.

"DIE!". The gathered chakra tipped over.

BOOM!! BOOM! BOOM!!

Multiple explosions run at the same time consecutively from a combination of explosive tags and self detonation from multiple clones assault. Broken limbs and flesh fell down from the sky as a third of the platoon was taken out by Tsuyu's offensive.

"Impressive." Sai made a comment quickly as he looked over.

"Not worth mentioning." Tsuyu looked at the art she made with a little smile.

The assault on the sky lasted only for a minute as the group reached the top of Ancor Vantian without difficulty. What met them was hundreds of Sky Shinobi were already ready for battle.

But they already lost their advantage the moment Konoha shinobi landed.

Might Guy, with youthful rage and anger stepped forward. Might Guy had never felt this angry, seeing close to two-thirds of Konoha destroyed and having so many people lost in a single moment.

"For destroying my home, I will show you the true power of youth! Gate of View - Open!" Might Guy opened the 6th Gate Directly and headed straight to hundreds of cannon fodders like a cannonball!

"S-Shoot!" The sky shinobi used their guns - but before they could even pull the trigger, Might Guy already threw a punch.

"Morning Peacock!" His punch was so strong the air pressure carried flames from the intense friction his punch carried.

The punch landed hard on the first unfortunate victim - causing his body to explode in a bloody mush - the force was still so strong that the flesh and bones smashed into tens of sky shinobi's behind him creating more mangled fleshes.

Tsuyu was quite shocked. She never thought Might Guy who she thought was a slightly silly adult was an actual monster. Her respect for him shot several levels.

Might guy on his own probably could have taken down half of the entire Sky Shinobi forces. Tsuyu didn't want to just watch and also began her own attacks.

Weaving hand seals - Earth Release - Earth Barricade! The variant of Earth Wall created barricades of earth on the battlefield with gaps in between - the walls grow consecutively outward, approaching the enemy, creating shields for Konoha shinobi while reducing threats of ranged weapons. The sky shinobi had chakra guns that shots fast projectiles and making the battlefield into closer range would be the wisest.

She made hand seals - creating 4 Shadow Clones containing a lot of her chakra. Tsuyu tossed to each of them a storage scroll containing Explosive Tags she had prepared. Tsuyu and her shadow clones created Earth Clones and attached them into those Earth clones with quickness and order.

"Go!" Tsuyu ordered them in a matter of seconds of preparation.

The shadow clones lead the charge, followed by tens of Earth clones.

Earth Release: Earth Wall. Earth Release: Earth Pillar.

The shadow clones created chances and space for the Earth Clones to get close, even tossing them directly to the middle of enemy formation before they exploded in a 3 meter radius explosion. Explosions keep ringing as the clones work in tandem - along with limbs and flesh torn apart.

Both strategy and raw brutality made Danzo and other shinobi on the field impressed and in awe of Tsuyu, who were very young.

The seasoned shinobi behind her also began their attacks, avoiding the sides where Tsuyu and her clones were to avoid being hit by her tactics.

Tsuyu was feeling mental ache and pain from the shadow clones being destroyed and torn apart at intervals, but her expression had a satisfied smile seeing her results, turning enemies into corpses in a matter of seconds. It was really because she finally got to show the result of her effort and training completely, and that seeing the barbarians who destroyed the village for nothing died, she smiled more out of satisfaction.

But onlookers that noticed the smile all had different ideas and had fear and chill creeped into their spine.

Kakashi on the other side, killed multiple shinobi in seconds with Raikiri slicing them in halves and cutting their limbs. Blood splattered all over the battlefield as hundreds of Sky Shinobi fell. He watched Tsuyu for a second, seeing her prowess in real battle and how she was unflinching at the sight of corpses and blood. But that smile…

Minato sensei… will you be proud… or will you be worried? Kakashi wondered what Minato would think of his daughter if he saw her mercilessly killing them with a smile on her face at the moment.

Everyone almost collectively forgot Tsuyu was only 10 and half years of age because of the abilities and the killing intent emanating from her on the battlefield.

They killed their way into the Ancor Vantian main chamber - where Shinno was waiting as if he was the last boss.

As the group entered, he laughed maniacally.

"Look what we got here… Bunch of ants sending themselves to death! Nnhahaha!" He let out wave of dark chakra, sending massive pressure onto all of Konoha Shinobi.

A Hyuga at the back exclaimed in shock at seeing the overwhelming chakra from him.

"His chakra! It's… It's almost like a bijuu!"

The troops of Konoha felt a little panicky.

Shinno smiled in satisfaction and ego, seeing them cower. But before he could even talk, someone - Tsuyu - threw a Kunai right onto his face. He casually bent his head, dodging them as if looking down at them as a joke.

But in slow motion, as the Kunai was passing right next to his head he heard a psst… sound. His eyes darted to see an explosive tag was attached right on it!

BOOM!

The explosion blasted Shinno's head half open. And he dropped dead with a thud.

…

"Huh?" The Konoha forces were surprised.

After a second of processing, they breathe a sigh of relief. The moment Tsuyu heard the Hyuga said he had a chakra of a bijuu, she was not taking chances.

But then seeing the scene in front of them, everyone gasp, even Tsuyu had her eyes widened in disbelief seeing Shinno's head regenerate quickly as his body stood.

"DAMN YOU!" He felt so offended by whoever threw the kunai at him. And the explosive tag was really potent too! It was a specially made tag, after all.

Tsuyu was solemn. If half of his head being blasted can't kill him… then would she need to blast all of his head?

"Konoha shinobi! Today will be your death day! Gate of Life - Open!" The burst of chakra spread all over his body - his muscles ripping as if about to rip himself apart.

"HAHAHA. It's my first time to use this much power. Let's test it!"

Shinno with massive speed rushed towards Konoha shinobi. He received multiple jutsu and hits from them, and returned blow after blow, knocking each of them with a single punch or kick. Tsuyu also landed blow after blow, using Raging Fist that could crack bones each time it hits - and even Herculean that blew his arm off completely. But whenever his limbs and body received damage, they regenerated and became even more powerful! Tsuyu stopped hitting him and left the rest to the others.

A Hyuga tried to use 64 palms to seal his tenketsu - but his skin and chakra layer protected his tenketsu! Shinno slapped him, sending him to crash into the wall right after.

With a sadistic laugh, he mocked them.

"I am invincible!" He wanted to use more power and see how far he could go.

"Gate of Limit - Op- Arrhh!!!" Shinno suddenly felt extreme pain inside his body. As if insects were constantly digging and eating him alive inside out.

"Ark! W-what's…happening… AHHH!!!" Shinno felt his entire body suddenly agonizing pain as if ants were grinding into his skin and deep into his bones and flesh.

"Ahh!! Ahh!" He screamed in agony as he used more and more chakra to regenerate. But the more chakra he used, the more the insects Rinkaichu of Aburame's clan multiplied and his body regeneration couldn't keep up. Danzo was here, naturally his strongest Root member was also here - Torune Aburame. Shinno having a mere chakra battery from Reibi and regeneration; while having no useful jutsu at all to counter meant there's nothing he could do.

The Nara clans used their shadow binding jutsu to hold him still. The insects eventually eat him close to being clean, only a small blob of flesh left. Truly, what a terrifying insect. The last boss died miserably, overestimating himself and underestimating Jonin of Konoha.

But just then, a terrifying wave of dark chakra came out the dark blob of flesh, appearing as ten of meters tall, pitch black creature akin to a worm!

It let out a cry, much like an infant. And to everyone's shock, before anyone could react, that thing went to Tsuyu and entered her body!

"What the f-"

***

Tsuyu was pulled into her subconscious space. She saw that snake-like thing was constantly swimming in the air and pressing itself against the Red Gates where Kyubi was living in. Kyubi and Reibi looked at each other, while Reibi was constantly crying as if calling to him.

Kyubi was silently observing… he stretched his finger, and Reibi was actually rubbing its head on his finger.

"Kyubi-san. What's that? You know it?"

"… No. But…"

Kyubi can feel the connection. As if they were siblings. Much like other tailed beasts. But since when has he had a little brother looking like this? Hagoromo only created 9 of them. So what is this thing?

But still, Kyubi can hear the cries of the infant-like Bijuu. As if trying to seek protection from its brother. That's why it went directly inside Tsuyu. Kyuubi as the big brother naturally would want to shield it. Reibi went to slither along Kyubi's finger towards his arm and actually entered the seal and rested snuggly against Kyubi's fur. The gap of the seal had widened considerably for it to enter willingly.

Tsuyu felt that was kinda cute. Anyway, she could just kick it out easily too, but seeing Kyubi's reaction to it, and that thing wasn't exactly hostile to her for now, she let it and Kyuubi be.

She returned to the physical world, only to see everyone looking at her as if she was an enemy. That thing seemingly tried to possess her, so it was understandable.

She raised her arms, telling everyone it was fine and let everyone drop their guard a little. Danzo quickly went to her to ask what's going on and she explained what she had experienced - and Danzo being Danzo had a Yamanaka check inside of Tsuyu's mindscape to confirm it and already had the sealing squad ready.

Konoha forces captured the remaining living Sky Shinobi and took over Ancor Vantian. Danzo thought at least they had this Sky Fortress and perhaps their technology to prepare for the upcoming event. The attack on Konoha will surely trigger a war later. Konoha lost half of its entire force in a matter of a single day after all. Danzo's face darkened at the thought of war.

Danzo already planned ahead as to what to do to protect Konoha and its people. No matter the cost, even his humanity.
