"Boom! Boom, boom, boom!" Two ninjas with monstrous strength were locked in a fierce battle. Every collision of their attacks made the backyard tremble.
Fortunately, this place was a detached villa.
It would not disturb anyone else.
However, Kurenai, who had been fast asleep, was not so lucky. Woken by the commotion, she rushed in panic toward the source of the noise...
"Huh? Why is Seiryū sparring with Tsunade-sama?"
Her hair was a bit messy, but it could not hide Kurenai's cuteness. She looked curiously at Shizune beside her. "Shizune, did Seiryū make Tsunade-sama angry again?"
Shizune: "..."
She did not know.
She had been halfway through cooking when she heard the noise.
She had put down her work and come over, also looking puzzled.
After a pause, she said helplessly, "Perhaps. Because Tsunade-sama swindled five million ryō from Seiryū, he has had some grievances against Tsunade-sama lately..."
Kurenai nodded. "It's possible."
As one of the people who knew Seiryū best.
She clearly understood how much he valued money. Being swindled out of five million ryō, it would be strange if he was not angry.
He had probably just recovered from his injuries and wanted to settle the score with Tsunade-sama.
"Five million ryō? What five million ryō?"
Jiraiya heard their conversation and curiously leaned in. "Is Seiryū that rich? He actually had five million ryō for Tsunade to swindle?"
"Oh, it's Jiraiya-sama."
Only then did Kurenai notice Jiraiya. After greeting him respectfully, she said, "I'm not sure about the details, but it seems to be compensation given to Seiryū by the Uchiha Clan."
"However, Tsunade-sama withheld it. Because the money was in Tsunade-sama's hands, Seiryū had no choice but to be swindled, so... Seiryū has had a lot of grievances against Tsunade-sama lately..."
Jiraiya: "..."
The way this master and disciple interacted was indeed a bit strange.
However, watching the two still fighting, he felt emotional.
This kid Seiryū, had his strength already become this powerful?
Although Tsunade was not completely serious, she was still using considerable strength. He did not expect Seiryū to actually block her attacks...
With this level of strength, he was probably not weaker than an average Jōnin.
He really was a little monster.
"Boom!"
In the arena.
Two fists collided once again.
This time, wind pressure surged, raising dust all around...
"Thump, thump, thump..."
The force transmitted through his arm made Seiryū retreat uncontrollably.
His right arm was also numb, but it was eased by pale green Kaidō chakra...
Shaking his arm, Seiryū looked indignant. "Aren't you being too ruthless? It's one thing not to let me use one hand, but you're actually using that much force. I'm not fighting anymore!"
Tsunade sneered. "Heh, you say you won't fight, so you won't? It's not that easy. Without my permission, you can't stop even if you want to."
"Boom!"
The punch landed, cracking the ground, but Seiryū dodged it.
Landing elsewhere, Seiryū looked at Tsunade unhappily, gritting his teeth. "Fine, fine, fine, that's how you want to play? Then don't blame me!"
He had already conceded.
This bad woman kept pushing, it was infuriating.
Then he would not hold back.
Seiryū snorted coldly. "I haven't forgotten you swindling me out of five million ryō. Old grudges and new ones together, I must give you a 'deep' lesson today!"
"Bakudō #63: Sajō Sabaku!"
He formed seals with one hand and spread the five fingers of his right hand.
Several golden chains, as thick as a human arm, extended from his palm, winding toward Tsunade like spirit snakes.
"Adamantine Sealing Chains? No, that's not right, they're just somewhat similar..."
Looking at the incoming golden chains, surprise appeared in Tsunade's eyes.
At first, she thought it was the Uzumaki Clan's Adamantine Sealing Chains.
But on closer inspection, it was not. It was only somewhat similar.
It must be a new jutsu that Seiryū had developed himself, yet it had a similar effect.
"Good kid, when did you develop this kind of sealing jutsu?"
Tsunade smiled.
She was no longer very surprised.
The speed at which this kid developed new jutsu might be faster than others learning ninjutsu.
"Swish, swish, swish!"
Using Body Flicker repeatedly, Tsunade dodged the golden chains trying to bind her.
While dodging, she also closed the distance to Seiryū.
She raised her long right leg and brought it down heavily.
"Boom!"
The immense force cracked the ground, fissures spread outward, strong winds rose, and shockwaves scattered.
"There are still many things you don't know. How could you imagine my talent!"
Using Shunpo to dodge again, Seiryū formed seals and pointed a finger.
"Sss, sss, sss!"
Six beams of light appeared out of thin air and struck Tsunade's waist, instantly restricting her movement.
Seiryū formed a seal and pushed his right hand forward. "Hadō #33: Sōkatsui!"
A scorching white flame expanded from his palm, forming a surging curtain of fire that engulfed the front.
"I haven't underestimated you, brat."
Watching the attack approach, the white flames reflecting on her face, Tsunade narrowed her eyes. "Use whatever moves you have."
Her monstrous strength erupted, directly shattering the Rikujōkōrō into fading specks of light.
At the same time, she raised her right leg and stomped down.
With a boom.
The earth shook, a huge rock rose up, blocking the flames.
Amid the roaring sound, the arena was filled with shattered flames and smoke...
"Bang! Bang, bang, bang!"
Stomping the ground, Tsunade leaped into the air.
Chakra burst from her feet, allowing her to step on air as she rushed toward Seiryū.
Her fair fist clenched as she smashed down.
"Bang!"
The punch was about to hit Seiryū but was blocked by a semi-transparent circular barrier.
"Huh?"
Tsunade was surprised.
What kind of jutsu was this?
Looking at her, Seiryū spoke calmly. "A barrier-type sealing jutsu focused on defense, Bakudō #60: Rikujōkōrō."
In this form, it acted as a barrier seal that could block frontal attacks.
Thinking about it, Seiryū had lacked strong defensive methods before.
Bakudō #60 filled that gap.
"A defensive barrier? You really are getting more monstrous..."
Tsunade sighed.
"Clatter!"
Before she could think further, a sound came from behind.
The golden chains attacked again, winding toward her.
"However, if you want to teach me a lesson, this is not enough."
A smile appeared on Tsunade's lips as she exerted force again.
With a crack, the barrier shattered like glass.
Her punch continued forward, striking Seiryū, though she pulled back slightly at the end.
"You'll know soon..."
Seiryū chuckled.
Just as the punch was about to hit him, he formed seals and spread his fingers.
A ball of light appeared in his palm.
"Hum!"
The light exploded, blinding everyone except Seiryū.
Hadō #20: Shōtenkyū.
It worked like a flashbang.
Its attack power was weak, but its effect was excellent.
"Bang..."
Tsunade was struck by the light and instinctively closed her eyes.
Her punch hit Seiryū, but it turned into smoke.
"This kid has too many strange jutsu..."
Tsunade realized she had hit a Shadow Clone.
With the blinding light, and her weak sensory ability, she could only defend passively.
She had not forgotten Bakudō #26: Kyokkō, which could obscure vision and even mask chakra.
This brat had too many strange techniques.
She could not fully grasp his abilities.
"Clatter!"
The golden chains continued attacking from behind.
Tsunade dodged again.
"..."
Her vision had not yet recovered.
She listened carefully, but heard nothing else.
"Let you underestimate me. Take this, Kaidō!"
Seiryū pointed forward, releasing pale green light.
It made almost no sound, and Tsunade was hit.
"Mmh..."
A strange, warm, comfortable sensation spread through her body.
She let out a soft moan.
Her cheeks flushed instantly.
Her eyes became watery and unfocused.
Her body trembled slightly as she bit her lip.
"You... bastard... how dare you use this jutsu... who allowed you..."
Her voice trembled, soft and breathy.
It sounded more like suppressed desire than anger.
"..."
Seiryū sighed inwardly.
It was truly a feast for the eyes.
Tsunade, usually bold and heroic, now showed a delicate side.
It created a striking contrast.
His heartbeat quickened, but he smiled. "I've discovered Kaidō can have unexpected effects."
"How does it feel? This time it's stronger than before."
Who said Kaidō could only heal?
Its peculiar nature made it useful in other ways.
It was even more extreme than the Sexy Jutsu.
On himself, it felt like soaking in a hot spring.
On males, it caused strange reactions.
On females, the effect was far stronger.
As his strength grew, so did its effect.
It was too improper.
As he spoke, Seiryū used Kaidō again.
"Mmh..."
Tsunade moaned again.
Her breathing grew heavier, her body trembling more.
Her legs weakened, and she knelt.
"..."
Supporting herself on the ground, she struggled to suppress further sounds.
Her charm reached its peak.
"..."
Even Seiryū felt uneasy under her gaze.
He calmed himself and used Bakudō #26: Kyokkō to conceal them.
He could not let others see.
Especially Jiraiya.
Walking closer, he crouched and smiled. "How is it? Do you admit defeat?"
"You... brat..."
Tsunade glared at him, her voice soft yet annoyed. "Just wait..."
"Heh, still stubborn?"
Seiryū smirked. "Admit defeat, or I'll use Kaidō again. Three, two..."
"..."
Tsunade bit her lip.
This brat.
How did he create such a jutsu?
She had only been hit twice, yet she felt weak.
Her mind was drifting.
"You brat... don't get arrogant... making me admit defeat... impossible!"
Just as Seiryū was about to say the final number...
Tsunade suddenly grabbed him.
Pulling him into her arms.
Then...
Her lips pressed directly against his.
Her mind was hazy.
Her solution was simple.
If she blocked his mouth, he could not finish counting.
She would not admit defeat.
(To be continued.)
