Naruto with OPM System

The afterglow of the setting sun bathed the Academy, enveloping the school in a blanket of golden light and shadow.

Within the classroom, near the window, a handsome young man gazed quietly outside, his already striking features enhanced by the soft sunset glow.

Beside the handsome youth stood a beautiful black-haired girl, her dark eyes brimming with a blend of curiosity and affection as she watched him silently.

"What's on your mind, Tenku? Nervous about the Genin exam?" the girl asked softly, her gentle voice giving some comfort.

"Yeah, I gotta work hard for our deal, my future wife!" Tenku replied, shifting his gaze towards the girl with dark hair, his words laced with sincerity and determination.

Her cheeks flushed hearing his endearing words, her big eyes getting all shy. Her cute ears looked even better in the soft light of the sunset.

Tenku looked at the little girl, his hand holding hers, their fingers laced together. She looked shyly up at him.

The girl in question was none other than the gentle and thoughtful Mikoto Uchiha from [Naruto], currently Tenku's girlfriend.

They had a deal.

After Tenku became a full-fledged ninja, he'd marry Mikoto Uchiha.

If Tenku becomes a Shinobi, Mikoto Uchiha would willingly marry him and let him do whatever he wants.

Determined, Tenku diligently pursued this goal.

Regrettably, his classmates in the class were formidable individuals.

Namikaze Minato, Akimichi Choza, Nara Shikaku, Yamanaka Inoichi, Aburame Shibi, and Uzumaki Kushina were really giving Tenku a hard time, especially since his Sharingan had yet to awaken!

[Ding! EXP +1]

Suddenly, a line of text popped up right next to Mikoto.

Upon witnessing this, Tenku's brows furrowed slightly, a tinge of surprise stirring within him.

[Ding! EXP +1].

Another line of text popped up in front of him.

Tenku took a hard look at the message, realizing it was from Mikoto.

'What in the world?' Tenku puzzled, his expression contorted in bewilderment as he tried to make sense of the unexpected turn of events.

"What's wrong, Tenku?" Mikoto asked, noticing Tenku's intense gaze, a hint of shyness evident in her eyes.

[Ding! EXP +1]

[Ding! Due to the owner's prolonged interaction with the plot characters, the One-Punch Man system has reached the activation conditions!]

[Ding! Congratulations to the owner for acquiring the Saitama Superhuman Physique [Enhanced Version]. Would you like to accept it?]

The mechanical voice suddenly echoed in Tenku's mind, prompting a smile to curl at the corners of his lips.

'So, as a reincarnator, I also have my own perks,' Tenku mused inwardly, a sense of realization dawning upon him.

He was about to turn 12, and the Genin exam was coming up. He'd always thought he was pretty average, nothing special.

However, it appeared that he had simply not met the initial requirements.

[Ding! Saitama's Superhuman Physique, in its enhanced version, will not induce hair loss, render the owner impervious to minor injuries, maintain emotional stability, and exponentially boost of strength. Would you like to accept it?] the system repeated.

"Definitely!" Tenku swiftly responded without any hesitation.

He'd watched One-Punch Man numerous time, he was well aware of the protagonist's formidable physique, surpassing even that of a god.

Now, on the brink of acquiring this physique, enhanced to an even greater degree, Tenku's strength would undoubtedly soar.

He was determined to make the most of this incredible opportunity.

[Ding! Congratulations to the owner for obtaining the Saitama Superhuman Physique Enhanced Version].

[Ding! Due to this enhanced physique being stronger than the original, it will gradually merge with you over the next few days. Consequently, your power control may be slightly diminished during this period, and your Chakra cannot be temporarily mobilized.]

Ding!

Tenku examined the data panel, his heart brimming with excitement.

Possessing the Saitama superhuman physique allowed him to use EXP to enhance various attributes.

This easy method of advancement brought immense joy, as he eagerly sought to accumulate EXP points effortlessly.

"Ouch, Tenku!"

A quiet voice of pain came from his girlfriend, Mikoto.

"What's wrong?" Tenku swiftly turned towards Mikoto, seeing her red hand from his grip, making him realize.

'As the bodies merge in the next few days, I'll lose some control. I gotta be careful not to accidentally hurt Mikoto,' Tenku thought anxiously.

He focused on controlling his strength, making sure he didn't accidentally hurt Uchiha Mikoto.

This kind-hearted girl, his future wife, deserved utmost care and protection.

Ring! Ring! Ring!

As the crisp school bell chimed, signaling the end of the day, students gathered their belongings and prepared to depart.

Tenku and his peers followed suit, hand in hand, exiting the school premises.

However, upon stepping outside, a serious-looking teenager blocked their path—Uchiha Fugaku.
