"Um?"
Leo stood with his arms crossed inside his towering Susanoo, a faint smile playing at his lips as he noticed the sudden transformation occurring in Might Guy.
"It seems you've finally made up your mind..."
"I have to say... I'm looking forward to this."
His crimson Mangekyō Sharingan spun violently as he spoke.
The power he inherited from Uchiha Madara was overwhelming—nearly peerless.
But now, for the first time since arriving in this world, Leo found himself... excited. Deep inside, he craved an opponent who could truly stand toe-to-toe with him, one who could push him to his limits.
And now—
"Kakashi!"
Guy's voice rang out.
He turned toward his old rival, who was fighting desperately against the shadow clones of Leo's Susanoo. Blood stained Kakashi's flak jacket, wounds running along his arms and abdomen. Yet despite his injuries, he continued to channel chakra alongside the other Konoha Shinobi, launching jutsu after jutsu at the seemingly unbreakable Susanoo avatars.
When he heard Guy call out, Kakashi instinctively pulled back from the clones, retreating to a safer distance. He turned, his breathing ragged, eyes meeting Guy's across the battlefield.
"Guy…!"
"Kakashi," Guy said, a warm but serious smile on his face. "This time… I win."
The words hung in the air.
Lifelong rivals. Eternal competitors. Though Kakashi often triumphed, in this moment, Might Guy believed with all his heart that the tide had turned.
Kakashi's heart sank.
"Guy… what are you planning?"
Just then—
Zheng—!
All of Leo's [Susanoo: Third Stage] clones suddenly halted.
Then—
Whoosh, whoosh, whoosh—!
They vanished. Dissipated into shimmering energy.
Their chakra flowed back into the original Leo.
He knew what Guy was about to do.
And for the first time since his reincarnation, Leo wasn't about to take his opponent lightly.
He withdrew every ounce of dispersed chakra, canceling the teasing battle with the Konoha forces. This fight was no longer a game. This was about respect—about honor. Because Might Guy... was about to go beyond human limits.
Only Guy, in this entire battlefield of elite shinobi, had earned Leo's full attention.
...
Tsunade, arriving at the right time, landed near Guy and stared at him in surprise and hope.
"Guy… have you truly reached that level?"
"Hokage-sama," Guy said, slowly lowering himself into a stance as his chakra began to swell. "Please move everyone away from here... Because the Blue Beast of Konoha is ready to bloom—burning every ounce of his youth for the sake of the village!"
His voice thundered with resolve.
Leo could have interfered—could have struck before the transformation—but he didn't.
He wouldn't.
Instead—
Squeak—
Inside the head of his Susanoo, blood began trickling from Leo's right eye.
Without hesitation, Leo reached up—gouging out his [Right Eye: Mangekyō Sharingan].
In a hidden movement, he stored the eye within the system's internal space.
Immediately after, he applied basic medical ninjutsu to stop the bleeding, and—
Hiss—
A new eye appeared in its place: a standard Three Tomoe Sharingan.
Now, his left eye still burned with the power of the Eternal Mangekyō, while his right eye had reverted to a more stable form.
Despite drawing back his Sharingan power, Leo's focus hadn't wavered.
He was preparing in his own way.
...
"Sensei…!" Lee cried out, tears brimming in his eyes.
He could feel it. The end. The peak. The cost.
"Lee! Be strong!" Guy shouted back to his student. "Carry your youth onward, no matter what!"
Then—
Before the eyes of every Konoha shinobi on the field:
"Eight Inner Gates Formation…"
"The Eighth Gate... the Gate of Death... OPEN!!"
BOOM—!
A massive surge of power burst from Guy's body as blood-red steam erupted into the air.
His body transformed, cloaked in an aura of steam so thick and violent it warped the surrounding air. The man himself was blood-soaked, muscles tensed, veins bulging.
He was terrifying.
He was beautiful.
"Teacher Guy!!" Lee sobbed uncontrollably.
Zheng huuuu—!
The sheer pressure radiating from Guy caused massive gusts of wind to blow outward, forcing many shinobi to shield their eyes.
"Guy…" Kakashi muttered, his own arms raised to block the oncoming force.
His mind flooded with memories—memories of when he first met Might Guy as a boy.
His father, the White Fang of Konoha, had said then:
"That boy… Might Guy. He'll become a truly great ninja one day."
At the time, Kakashi hadn't taken it seriously.
But now—
"Father… You were right."
...
"This chakra…"
Hyuga Hiashi's eyes widened as his Byakugan flared. Alongside him, Neji and Hinata also activated their dojutsu, stunned at the overwhelming force.
Even Tsunade was breathless, awed by the display.
But beneath that awe—was grief.
She, like the others, understood the cost of the Eighth Gate.
The Gate of Death was not named lightly.
...
But in this moment—none of that mattered.
Because Might Guy had become a force of nature.
And even Leo—wielding the full strength of Madara Uchiha—was stunned.
"This chakra... this steam…"
"I recognize you now, Guy."
"Then come… let's dance!"
...
Leo's Eternal Mangekyō Sharingan flared to life once more.
He took a deep breath.
"I'll go all out too!!"
BOOM—!
The already massive [Susanoo: Third Stage] began to expand.
Flesh turned to flame.
Steel turned to spirit.
The avatar grew and grew, towering now at over 80 meters.
Gasps echoed across the battlefield.
"He's still growing it?!"
But Leo wasn't done.
"It's not over yet."
"Complete it."
He smiled, slowly clenching his right fist.
Shua—
Zheng zheng zheng—!!
Energy surged across the Susanoo as it began to manifest armor—real armor—gleaming with blue light and jagged design. The skeletal frame gave way to muscle, form, and solidified chakra plating.
Until—
Standing in front of the entire Konoha force...
Was the complete Susanoo.
Towering. Glowing. A god of war.
A perfect match for Might Guy, who now stood as the ultimate taijutsu warrior.
The final clash was upon them.
The Blue Beast of Konoha, burning his life away—
Versus the Reincarnated War God, Leo.
