What is the true spice of a secret affair?

If Suzuki had to explain why his private exchanges with Yugao were so incredibly addictive, it all came down to the thrill of the forbidden.

He knew it was wrong. He was absolutely certain Yugao knew it was wrong. Yet, because they spent all day suppressing their desires—acting like perfectly professional ninja under the watchful eyes of the village—the moment they finally locked the door, everything just erupted. Once they were alone, holding back was simply no longer an option.

Why were they currently awake before the sun even started to rise?

Because Tsunade and Shizune were heavy sleepers who rarely woke up this early. This stolen window of time was their absolute playground. Hidden away from the rest of the world, they let themselves fall completely into a forbidden, intoxicating rhythm.

Yugao was simply too tempting. The contrast between her deadly, stoic ANBU persona during the day and the flushed, breathy mess she became behind closed doors was enough to drive any man crazy. And Suzuki? With his Manager actively optimizing his physical stamina and his absolute mastery over Yang Release, he possessed an unfair advantage.

His physical endurance was practically limitless. Under his relentless pace, a high-ranking ANBU captain was reduced to melting into his sheets, completely at his mercy like a heroine in a late-night romance novel.

Sometimes, Suzuki had to pause and wonder about his own life. He had always considered himself a calculated, low-key guy. How did he suddenly end up perfectly fitting the mold of the "Four Horsemen of the NTR Genre"? It was a bizarre, self-aware realization, but frankly, he wasn’t complaining.

Still, their time together wasn’t strictly confined to the bedroom. When the sun came up, the tangled sheets were swapped for wooden swords, and their intense exchanges moved to the training grounds.

Initially, Yugao had been the strict teacher. But with the Manager recording and optimizing every swing, Suzuki quickly decoded her legendary swordsmanship and started pushing it even further.

Make no mistake—Yugao was incredibly deadly.

She was an ANBU Captain. In Konoha’s hierarchy, standard ANBU are elite killers hand-picked by the Hokage. To be a Captain meant Yugao comfortably operated at a High-to-Elite Jonin level. Her absolute specialty was Kenjutsu (Swordsmanship). She was considered one of the foremost blade experts in the village, having trained extensively with her late lover, Hayate Gekko.

Her signature moves were terrifying. The Dance of the Crescent Moon was a complex, A-rank assassination technique where the user created two shadow clones mid-swing. All three bodies would strike the opponent simultaneously from three different blind spots.

Many modern ninja looked down on traditional swordsmanship, but Suzuki knew exactly why Yugao’s style was so lethal.

The Dance of the Crescent Moon didn’t just rely on speed. It was a localized sensory overload. When three blades suddenly appear from three different blind spots at the exact same time, the opponent’s brain physically stutters. It tries to calculate the distance, speed, and trajectory of all three attacks at once. The human brain—and even standard tracking eyes like the Sharingan—experiences a split-second of "lag" under that massive processing load, making the strike feel instantaneous and entirely unavoidable.

Combine that with Hayate’s Transparent Escape Jutsu—which Yugao had also mastered—and their sword style became a nightmare. By camouflaging their bodies while moving at high speeds, they created a strobing effect. They flashed in and out of the enemy’s vision, completely destroying the opponent’s ability to gauge distance.

Honestly, Suzuki thought, the only reason Hayate died to that Sand Ninja was all due of a plot.

To Suzuki, Yugao’s sword style wasn’t just swinging a sharp piece of metal; it was the art of hacking the opponent’s brain. It relied on optical illusions, shattering the enemy’s kinetic vision, and completely scrambling their sense of rhythm before delivering the killing blow.

But Suzuki could take that concept and push it to a terrifying new extreme. He didn’t even need shadow clones to replicate the effect.

"How...?"

Yugao stood in the center of the training ground, completely dazed. She felt like she was trapped in a thick, disorienting fog. Suzuki hadn’t even used a jutsu, yet just by watching the way his body moved, she was completely losing her sense of direction, distance, and time.

"I’m just hacking your rhythm," Suzuki said, lowering his wooden blade.

"My rhythm?"

"In any real fight, people naturally fall into a beat," Suzuki explained simply. "Like a heartbeat. Step-strike, block-counter, one-two, one-two. My concept is to purposefully break that rhythm."

It was essentially a lag switch. Suzuki would move slightly off-beat—hesitating for a fraction of a second before a strike, or stepping uncharacteristically slow. This completely short-circuited the opponent’s reaction cycle. By the time Yugao’s brain registered the "slow" movement and decided how to block it, Suzuki had already accelerated to maximum speed and had his blade at her throat.

Stillness. Sudden, explosive bursts of speed. Sensory disorientation.

While Yugao had to rely on chakra and jutsu to trick the brain, Suzuki was doing it purely through the terrifying physics of his body movements.

If I pair this with invisibility, my enemies are already dead, Suzuki calculated silently.

His setup was practically a cheat code. He was Tsunade’s personal disciple, which meant it was only a matter of time before she taught him how to focus his chakra to gain the physical strength of a giant.

The raw, earth-shattering power of a giant combined with the untraceable, rhythm-breaking invisibility of an elite assassin? He didn’t need massive, flashy elemental explosions. Those two simple, perfectly optimized concepts alone would make him one of the deadliest ninja on the continent.

"You should go rest," Suzuki said gently, pulling his thoughts back to the present. "You’re exhausted."

"Um," Yugao nodded softly.

Suzuki’s stamina was just too monstrous. While she was an elite ANBU, she was still human. Her body had limits, especially considering how many times he had pushed her past the breaking point late last night.

As she turned to leave, her hair was tied up in a messy, casual ponytail. The style offered him a tantalizing glimpse of her pale, damp nape. His eyes trailed down the curve of her back to the tight fit of her training shorts, highlighting the smooth shape of her hips and her long, toned legs.

Suzuki quickly forced himself to look away, taking a deep breath to cool his sudden spike in body temperature.

He definitely needed a bath. Naturally, he didn’t follow her to the same bathroom. If he did, he knew his "rest" period would instantly be canceled. As incredible as it felt, he needed to let the poor woman recover.

"So comfortable..."

A little while later, Suzuki sank into the steaming water of a luxurious, private hot spring. He had been staying at this high-end hotel in the city for days, completely ignoring the exorbitant room rates because his stay was entirely free.

Why? Because he literally owned the hotel.

Between his various businesses, investments, and the Manager’s financial optimizations, his liquid capital was staggering. He knew exactly how to wash money from the shadows and turn it into perfectly legal assets.

He closed his eyes, letting the hot water soothe his muscles.

Suddenly, his heightened senses flared. His body tensed beneath the water.

"Come out," Suzuki said, his voice dropping to a freezing, lethal register. "Or I will instantly boil this water and burn everything in this room to ash."

"...."

Silence.

"One... Two..."

"W-Wait, nyaa! Wait a minute, nyaa! Please don’t burn us, nyaa!"

A panicked voice squeaked from the shadows near the ceiling beams. "We aren’t bad guys, nyaa! We just want to do some business with you, nyaa!"

Suzuki blinked, utterly dazed as two small, furry figures suddenly dropped from the rafters and bowed furiously against the wet tiles, begging for forgiveness.

"...Cats?"

Finally, the world of Naruto!

Also, I have been thinking for a while about his animal summonings, and many of them are somehow crazily strong, yet for a strength, I think that he doesn’t need it, as he is pretty strong enough, so what is the most useful pet for him?

I found the answer, but please wait for the next Chapter~!
