"Kid, after you finish eating, let me check the results of your training."
At the dining table, Senju Tobirama set down his chopsticks and looked up at Renya.
Renya paused in the middle of eating when he heard this, and suddenly the food in his bowl lost all flavor.
His eyes caught the faint glint of a kunai peeking from Tobirama's sleeve, and he sighed inwardly:
Looks like this old guy isn't here for a friendly spar...
Damn it, he even brought a kunai in advance...
"I'm done."
Renya swallowed the last bite, casually gripped Immaculate at his waist, then stood up and walked toward the courtyard.
Senju Tobirama stared at the Uchiha crest on Renya's back, lost in thought.
...
The evening breeze carried sakura petals across the courtyard as two figures—one tall, one small—stood facing each other on the training ground.
Without hesitation, Renya activated his Sharingan, drew Immaculate in a reverse grip, and with a dragon-like whistle, the blade's sharp sound pierced the silence.
Just as the cold flash of steel brushed Tobirama's sleeve, his figure turned into a spray of mist—it was a Water Clone.
"Too slow."
A cold hand suddenly gripped the back of Renya's neck, making his hair stand on end. His Sharingan caught the distortion of air behind him.
"Water Style: Water Prison Jutsu!"
He spun around and slashed, cleaving through the transparent prison of water. As water droplets scattered, Tobirama sidestepped effortlessly.
"Pay attention, kid." Tobirama's hands formed seals. "Water Style: Great Waterfall Jutsu!"
Renya gritted his teeth and infused chakra into his blade.
As Tobirama's massive water jutsu came crashing down, arcs of electricity suddenly burst from Renya's body.
Using Lightning Style: Body Flicker Technique, he pierced through the waterfall.
This was the ultimate move he had developed over the years, inspired by the Lightning Armor of the Raikage. By stimulating his cells with Lightning Style chakra, he enhanced both his offensive and defensive capabilities.
Combined with the Body Flicker Technique, it even had a trace of the feel of the Flying Thunder God Slash.
Renya named it: "Budget Version: Flying Thunder God Slash."
Of course, the two were fundamentally different.
The Body Flicker Technique gathers chakra in the feet to explosively propel the user forward, achieving speeds beyond human perception and creating the illusion of teleportation.
The Flying Thunder God, however, is a space-time ninjutsu that uses a sealing formula to mark a target location, then twists space to teleport instantly between locations, bypassing all distance limitations.
Renya gripped Immaculate and lunged forward at blinding speed.
Tobirama froze for a moment as he saw the technique.
That familiar style reminded him of a certain battle—of how he had once used a similar surprise tactic to kill someone...
But now, their roles were reversed—he was the one being targeted.
Tobirama quickly came to his senses and used Water Formation Wall to defend.
Immaculate, crackling with lightning, slashed down, only to be deflected by the water-based mirror-like shield.
Renya had anticipated this. He borrowed the rebound force to leap up, twisted his wrist mid-air, and even formed a seal with one hand.
"Fire Style: Great Fireball Jutsu!"
Tobirama's eyes flashed with approval.
"One-handed seals, huh?"
He noticed Renya had simplified the seal sequence for Great Fireball, allowing for one-handed execution—but not every jutsu could be simplified this way.
The reason Renya learned one-handed seals was out of necessity!
With Immaculate in one hand, it wasn't realistic to resheathe the blade every time he wanted to use a jutsu.
So, he had to force himself to learn one-handed seals...
A massive fireball roared toward him with intense heat.
Tobirama swiftly formed seals and countered with another Water Formation Wall, neutralizing the fire.
The clash of Fire and Water Style created a dense cloud of steam, blurring Tobirama's vision.
Silently, Renya appeared behind him and slashed down mercilessly.
"Got you!"
Tobirama's body turned into mist once more.
"Heh... kid, you're still too naïve."
Tobirama suddenly appeared behind Renya, kunai in hand, aiming to stab.
Just as the attack was about to land, Renya smirked.
Seeing this, Tobirama's eyes narrowed in suspicion—but the next instant, the Renya in front of him dissolved into smoke.
"A Shadow Clone?" Tobirama's pupils shrank. "When did he...?"
"Hey, old man! Don't zone out during battle!"
Renya swung his blade at Tobirama.
But before he could celebrate, the figure once again turned into mist.
Renya: "???"
At that moment, Tobirama instantly appeared in front of him.
Renya was still wondering if this was another clone when Tobirama raised a foot and kicked him squarely.
BAM—
Renya crashed to the ground hard, blood seeping from the corner of his mouth.
The pain made him suck in a sharp breath. Damn, this old guy doesn't hold back at all...
"Kid, I'll return those words to you." Tobirama stood over him. "Don't space out during battle."
Renya got to his feet, wiped the blood from the corner of his mouth.
"Old man, the battle's not over yet."
He held Immaculate, showing no intention of surrendering.
Tobirama looked into Renya's cold eyes and couldn't help but think of Uchiha Izuna.
This kid is becoming more and more like Izuna...
In Tobirama's moment of distraction, Renya launched another attack.
...
The fight lasted for half an hour. In the end, Renya collapsed to one knee from exhaustion.
Tobirama stood under the corridor, holding a teacup that had somehow been refilled.
"Combining kenjutsu with dōjutsu... That's real progress compared to last time."
If it had been someone else, they might've fallen for Renya's trick.
After all, once someone was caught in the genjutsu of the Sharingan, even the slightest lapse of awareness would allow Renya to use Body Flicker and land a fatal blow.
Unfortunately, the Sharingan was useless against Tobirama.
As the person who understood the Uchiha better than the Uchiha themselves, there was no way he'd fall for one of their genjutsu.
The fact he didn't use [Infinite Darkness Jutsu]to bully Renya was already a mercy.
Still, Tobirama was genuinely surprised. Renya had come up with the idea of using Lightning Chakra to stimulate his cells, combining swordplay with his dōjutsu and flicker movement—this was true genius.
Tobirama stared at Renya, deep in thought.
Maybe I can teach him the Flying Thunder God... But can this kid really learn it?
After all, Flying Thunder God is notoriously difficult, requiring deep understanding of space-time theory.
And Renya's academic grades...
Sigh, forget it. I'll bring it up later.
If Renya ever finds out he missed a chance to learn the Flying Thunder God early just because of his test scores... who knows how he'd react?
Tobirama returned to the kitchen and brought back a glass of milk for Renya.
"Tomorrow, bring Danzō and Koharu over. I want to see how their training is going."
"Got it." Renya took the milk and drank it in one go.
Tobirama nodded with satisfaction.
"It's late. Get some rest."
Renya didn't overthink it and headed to bed.
...
In the laboratory, Senju Tobirama wore a white lab coat and held a syringe in his hand as he approached Renya.
His exposed eyes gleamed with excitement.
