Konoha: The thirty-year-old Uchiha is not motivated.

"Very good chakra."

Seeing the rising momentum of Number Four, Madara Uchiha rarely showed a serious expression. Judging from the quality of chakra alone, this imposter clone's power had completely surpassed that of the real Onoki.

"But a knight's battle doesn't rely entirely on chakra."

Madara Uchiha gently shook his head, raised his blood-stained sword, and swung it. A sharp blade of light sliced ​​through the thin mist, and several blue sword beams shot out.

Seeing that the sharp blade was about to slice Number Four into a human stick, he moved.

"Bah!"

It was the classic parry, only this time, a layer of dark red lava armor had appeared on top of the shattered gauntlets. When the blade struck it, it only produced a muffled thud.

"Oh?"

Madara Uchiha paused in his sword-wielding motion, a hint of curiosity flickering in his eyes beneath his mask.

It was a power he had never seen before.

After blocking Madara Uchiha's attack, the surrounding crimson mist was finally completely absorbed by the abdominal opening at Number Four's waist.

"boom!"

The next second, dark red, gelatinous chakra gushed out from his gaping belly, transforming into streams of scorching magma that climbed up the number four red outer armor, flowing in a pattern resembling human veins.

Once all the veins converged at his chest, a brand new dark red armor appeared.
Within the veins running throughout its body, flowing magma shimmered with a golden-red hue like blood, perfectly embodying the true meaning of power within its heavy armor.
"This is?"

Having witnessed the fourth transformation, Madara Uchiha's curiosity deepened. He had beaten up Onoki before, but this was the first time he had seen the Four-Tails Knight in this enhanced form.

Feeling the intense energy within him, Number Four clenched his heavy fists, a flicker of desire for victory appearing in his empty eyes.
This power
Can win!
[Photon Lava Burst Pattern]

This is an enhanced form that materializes the power of the Four-Tails' Lava Release. It not only requires a large amount of tailed beast chakra as support, but also demands that the user have a strong will and be able to endure the unbearable high temperatures with a mortal body.
In this form, the Four-Tailed Rider's power and defense will be maximized. It boasts high health, high defense, and immense strength, with high damage output from both its left and right hands – a pure stat-based monster.
"Snapped!"

Number Four clashed his fists together, sparking bursts of fire. Having just received his enhanced form, he couldn't wait to test his current power.

"Boom!"

With a slight crouch, Number Four's eyes flashed with a sharp light, and scorching lava instantly erupted from beneath his feet, baking two large, dark craters into the hard ground.
"Boom!"

Using the recoil from the impact, his seemingly clumsy body displayed unprecedented agility, transforming him into a land tank as he rammed into Uchiha Madara.

"Boom!"

The commotion was so great that the entire island trembled slightly. Tsunade, her eyes filled with terror, clung to the rock wall beside her, unable to comprehend how a human could create such a disturbance.
"Well done!"

Madara Uchiha, who was seen as the target of the attack, appeared unusually excited. Facing the aggressive Number Four, he not only showed no intention of dodging but instead drew his sword and charged forward, his crimson eyes filled with fighting spirit.

"This is the kind of battle I've been wanting!"

"Don't fight!"

Watching the two figures about to collide, Tsunade let out a helpless cry. She didn't understand the meaning of this battle; she only knew that both sides fighting to the death were important members of her family.
"Tap!~"

Just then, a blue figure descended from the sky and landed beside Tsunade; it was none other than Uchiha Izuna, who had arrived late.
"What happened? What happened?"

"who are you?"

Tsunade warily watched the overly familiar blue knight, retreating while assuming a fighting stance. This suspicious fellow was the thief her aunt had cursed for years; he was definitely not a good person!

"Uh, I am his companion."

Uchiha Izuna opened his mouth, about to introduce himself, but then remembered his faked death. After a brief hesitation, he raised his hand and pointed at Uchiha Madara in the arena.

"Grandpa Ban would never be friends with a thief!"

"Who told you I'm a thief?!"

Enraged, Uchiha Izuna gritted his teeth and asked,
"You stole Grandpa Izuna's money!"

"."

Tsunade's answer left Izuna Uchiha speechless.
I stole from myself?
"Cough cough cough, that's all in the past. I've turned over a new leaf now. Tell me what exactly happened."

The past is too painful to recall, so he chooses to forget that accident and focus on the present.

Seeing Izuna's appearance, which resembled Madara Uchiha's, Tsunade frowned, but ultimately chose to believe him. She then briefly recounted what had happened.
"A clone similar to Erzhuzi?"

After listening to Tsunade's brief explanation, Uchiha Izuna nodded thoughtfully.

"Boom!"

At that moment, the two finally collided, and the shockwave from the collision nearly knocked Tsunade over.
"careful!"

Fortunately, Uchiha Izuna reacted quickly and grabbed the Senju clan's eldest granddaughter, preventing her from falling flat on her face.

"Thank you."

After regaining her footing, Tsunade's face was deathly pale, and she looked at Uchiha Izuna with a hint of gratitude in her eyes.

"Stand behind me."

Uchiha Izuna shook his head, gesturing for Tsunade to hide behind him so she wouldn't be injured by the aftershocks of the battle.
"Please try to persuade Grandpa Ban; that person isn't a bad person."

Looking at the blue figure blocking her way with a complicated expression, Tsunade spoke with a hint of pleading.
"I'm sorry, I can't interfere in his fight."

Even if Izuna had a hundred times the courage, he wouldn't dare disturb his elder brother, who was in the heat of battle. If he rashly went up, he might end up getting attacked as well.

"But."

"Don't worry, if what you say is true, I can guarantee that the clone's life will at least be safe."

If the clone fighting below is truly in the same situation as Erzhuzi, Big Brother will definitely show mercy.

Upon hearing this, Tsunade shook her head with a complicated expression.

"But I think Grandpa Ban seems to be having trouble holding on."

"what?"

Uchiha Izuna was startled upon hearing this and quickly looked towards the arena.
War is indeed unpredictable. Madara Uchiha, who was just evenly matched with the clone, was now being pushed back by his opponent, looking like he was about to collapse.
"What?! How is this possible?"

Izuna's eyes widened, and she cried out in disbelief.

"Boom~Boom~Boom~"

On the field, Madara Uchiha felt unprecedented pressure. Even when facing the power-type Eight-Tails, he had never felt this overwhelmed.

"How could a mere counterfeit product go to such lengths?"

Looking down at the furrows he had plowed at his feet, Madara Uchiha asked in a deep voice.

"I don't know why, all I know is I can't give up yet." Number Four uttered these words slowly and deliberately, each syllable an ordeal for him.
The scorching energy within him caused a burning pain all over his body; every cell felt like it was being bathed in lava. With each increase in strength, a large portion of his life energy was consumed.

This is the price of power!

"you"

"Boom!"

Madara Uchiha's eyes widened, as if he could see the chaotic state within Number Four's body. He was about to ask a question when he was struck squarely by the opponent's iron fist.
"Boom! Crack!"

The scorching fist, imbued with immense force, slammed into the protruding rock wall, leaving Madara Uchiha feeling dizzy and disoriented. The last time he felt this way was when he was directly struck by the Eight-Tails.
"Snapped!"

However, before he could catch his breath, Number Four, who had successfully launched a sneak attack, pressed his advantage, raising his clasped fists high and slamming them down towards Uchiha Madara's head.
"Susanoo Armor!"

At the critical moment, a red light flashed in Madara Uchiha's eyes, and indigo armor appeared out of thin air.

"Boom!"

However, Susanoo's strength was only slightly stronger than a plastic bag, completely unable to block Number Four's thunderous attack. In the instant Susanoo shattered, Madara Uchiha seized the momentary delay and sidestepped, barely dodging the giant fist that grazed his cheek.
Even through the mask, he could feel the stinging pain from the wind.

"boom!"

Taking advantage of the moment when Number Four's fist slammed into the ground, Madara Uchiha raised the tip of his sword and thrust it towards his opponent's relatively vulnerable armpit.
"Bah!"

Such thick armor.

Seeing the white markings on the fourth armor, Madara Uchiha had no choice but to change his approach and start looking for other weaknesses.

Unfortunately, things didn't go as planned. Number Four's defensive capabilities were now comparable to the Three-Tails, and no matter how he attacked, he couldn't inflict any damage on the opponent's dark red armor.
"Have you had enough? Now it's my turn."

Number Four silently raised his right fist, and the chakra gushing from his elbow transformed into scorching magma, enveloping his entire arm and instantly expanding in size several times over.
"have you eaten?"

"not yet."

Seeing the extravagant gesture of number four, Madara Uchiha subconsciously replied,
"Didn't eat? Then take this punch."

The next second, a fist bigger than his head slammed down, casting a massive shadow over Madara Uchiha.
"Kamenride~~~Kurama the Nine-Tailed Fox!"

At this critical moment, Madara Uchiha pulled out the Nine-Tails Card he had just stored away and, with all his might, pushed it into the card slot on his waist.
As the phantom of a fox's head rose, Madara Uchiha's crimson robes were replaced by red and white, and a cloak formed from nine fox tails crossed behind him, blocking his view.
"Oh!"

After a deafening thud, Madara Uchiha, still shaken, looked at his slightly trembling fox tail cloak and finally breathed a sigh of relief.
Fortunately, I had a card on hand: the Nine-Tailed Knight's power is a mechanic-based monster, which is perfect for countering enemies that rely solely on stats.

With a flick of his nine fox tails, Madara Uchiha swiftly retreated, creating distance between himself and Number Four. Watching the dark red, heavily armored knight silently retract his fist, a slight smile played on his lips.
"Your strength is quite impressive, but it will be mine in a moment!"

Having said that, he raised his accompanying weapon, which had transformed into a gunblade, and began his attack on Number Four in his former knightly form.
Kamen Rider Decade was just having fun; he found the Nine-Tails' power much easier to use.
Sensing Madara Uchiha's tendency to tire of the old and crave the new, Indra, hidden deep within Madara's consciousness, slowly raised his head, a barely perceptible hint of displeasure appearing on his usually indifferent face.

"A mere reincarnation"

How dare you look down on yourself?
You, as a reincarnated being, have chosen a narrow path!
However, he only muttered a small complaint in his heart about the ignorant Madara Uchiha, and did not choose to trip him up or make this reincarnated person suffer a setback.

Turning his head, Indra focused his gaze on the towering tree behind him, looking at the star-like greenery dotting the branches, a hint of anticipation appearing in his eyes.

"You bastard, you're finally waking up."

"Oh!"

"Bah!"

Wielding a spear blade wreathed in white light particles, Madara Uchiha moved at a speed imperceptible to the naked eye. The white particles, imbued with the power of Yin-Yang Release, slashed at Number Four, leaving wounds on his dark red armor that emitted bursts of crimson chakra.

"Pfft!"

Another sword fell, slicing a deep, bone-revealing gash across Number Four's chest. Severed veins spewed forth golden-red magma, which melted and left mottled marks on the ground.

"Admit defeat."

Madara Uchiha flicked his spear, spraying out the scalding blood clinging to the blade. The blood, imbued with the power of Lava Release, evaporated into the air before it even hit the ground.

"."

Number Four didn't answer, not because he was impolite, but because he was in too much pain to reply.
He forcibly infused every cell of his body with the power of Lava Release. This form couldn't last long; if he delayed even a few more minutes, he would completely turn into a lifeless mass of magma.

unless
There is something that can replenish his life energy.

Number Four frowned, and out of the corner of his eye, he suddenly caught sight of a small thing in the corner.

"That is."

Looking at the drawing of the grinning Shukaku, a slight thought stirred within him.
Number One is dead. This well-stocked outer shell will soon degrade automatically, transforming into a chakra core.
That's his best supplement!

Thinking of this, a glimmer of hope suddenly rose in Number Four's previously despairing heart.
Gurgle!

"what?"

Seeing Number Four suddenly roll away and create distance between them, Madara Uchiha, who was preparing his surrender speech, was stunned.
"Crack!"

After obtaining Shukaku's Hōzō, Android 4 did not use Android 2's Hōzō to enhance its transformation like Android 3 did. Instead, it directly crushed the Hōzō's outer shell into pieces.

While using Shukaku's Hideout can grant him some of Shukaku's abilities, its effect on him is far less significant than that of pure chakra.
"That's my trophy!"

It wasn't until Number Four stuffed Number One's chakra core into his abdomen that Madara Uchiha, belatedly realizing what was happening, finally cried out in annoyance.

If you eat it, how am I supposed to explain it to my older cousin?
He also wants new enhancement items!
"Well"

After swallowing the Chakra Pill, a cool power surged into his body, greatly relieving the burning sensation within him. The comfortable feeling made him let out a long sigh of relief.

"Come again."

With this emergency energy, Number Four regained the confidence to fight Madara Uchiha for three hundred rounds.

Madara Uchiha was unhappy; he had almost failed in his attempt to "reform" this clone.
He thought the opponent's health bar was about to be depleted, but then the opponent took drugs right in front of him, treating him, Uchiha Madara, like a dog.
"Damn it! I shouldn't have let them pass!"

He muttered curses as he pulled the Nine-Tailed Fox card, which had given him an advantage, from its slot, and the red and white figure returned to its flamboyant pink form.

He looked up at his younger brother not far away, about to call out, but then he caught sight of Tsunade beside him. He could only click his tongue inwardly and coldly command,
"Quan, give me the card!"

"Okay."

Sensing his older brother's bad mood, Izuna quickly tossed his card case over.
"despair!"

Madara Uchiha caught the black card box with a blank expression and pulled out eight Tailed Beast cards, stacking them together with the Nine-Tails card in his hand.
A blinding flash of light appeared, and the nine cards merged into one. This strange operation piqued Tsunade's curiosity.

"What is Grandpa Ban going to do?"

He was really angry.

Uchiha Izuna scratched his head helplessly. The last time his older brother was this angry was because Sasuke stole the chakra pills they had painstakingly collected.
Glancing at the card displaying silhouettes of the nine tailed beasts in his hand, Madara Uchiha reached behind him, and when he raised his hand again, a Decade-themed touchscreen was now in his grasp.
"The show is about to begin." (End of Chapter)
