Sasuke Uchiha’s Isekai Domination

Chapter 1: Sakura Haruno's Confession

As a shut-in otaku, Takahashi Haruto could only fantasize about anime waifus, game beauties, and lazing around while waiting for death.

Never in his wildest dreams did he imagine he would actually travel to another world.

When he opened his eyes, touched his face, jumped around, and felt his own heartbeat and breathing, he looked in the mirror.

“Oh my god!”

“I actually became Sasuke Uchiha?”

“Is this some kind of joke?”

Am I dreaming?

To confirm, Sasuke pinched his thigh. "Ouch!" The pain was real.

In the Naruto universe, while Sasuke might be the second male lead, his good looks and popularity rivaled that of the protagonist, Naruto Uzumaki.

“Wait a minute!”

“What time period is this?”

As someone who once lived his wildest fantasies in his dreams, the now-reincarnated Sasuke wasn’t nervous at all.

First, he decided to check his abilities.

“Wait a second! Where’s my system? A proper isekai needs a system!”

Sasuke called out, “System!”

To his astonishment, a transparent interface appeared in the void, accompanied by a voice:

[Host, I’m here.]

Sasuke marveled, “Wow, what a user-friendly system.”

[Thank you for the compliment, Host!]

“What kind of system do I have?” Sasuke asked. “How do I level up and complete missions?”

[This is the Invincible Check-In System. Simply trigger a check-in event to receive invincible rewards.]

Sasuke’s eyes lit up. “I love it! A check-in system is simple and fits my lazy personality perfectly.”

“So, where do I start checking in?”

[The Invincible Check-In System doesn’t assign direct tasks. It’s similar to the open-world gameplay in *Genshin Impact*—you’ll need to explore to find check-in opportunities.]

Exploration-based? Sasuke was intrigued yet slightly nervous. “Will it be hard?”

[Not at all, Host,] the system reassured him. [Simply touching certain objects will trigger hidden exploration missions and grant rewards.]

Nodding in understanding, Sasuke replied, “Alright then, let’s give it a shot.”

He searched around the room but couldn’t find anything to trigger a check-in.

“This might be trickier than I thought.”

Suddenly, he felt an itch in his eyes and rubbed them. To his surprise, the system chimed in:

[Congratulations, Host, you’ve successfully checked in. Reward: Eternal Mangekyō Sharingan upgrade.]

Instantly, his eyes burned with energy, as though a source of immense power had been unlocked.

“Damn!” Sasuke exclaimed, stunned.

“That was so easy? I just touched my eyes, and my Sharingan evolved?”

“Awesome!”

Excited, Sasuke continued exploring his body. He touched his arms and legs, but nothing happened.

Then, when his hand brushed near his abdomen—

[Ding!]

[Congratulations, Host, for checking in. Chakra level upgraded to Jōnin.]

In an instant, his dantian surged with overwhelming chakra, filling him with warmth. Sasuke felt so powerful that he believed he could kill an elephant with a single punch.

“I’m so strong now!”

Sasuke was elated.

Checking in had given him the Eternal Mangekyō Sharingan and chakra at the Jōnin level.

“As expected of the Invincible Check-In System! At this rate, the Naruto world is mine for the taking!”

He laughed maniacally. “Mwahahaha!”

Just as Sasuke was celebrating his newfound power, a knock came at the door.

Opening it, he saw a petite girl with pink hair standing outside. She wore a red slit dress resembling a qipao, accentuating her slender and alluring figure.

“Haruno Sakura…”

Sasuke was surprised. Up close, Sakura’s delicate skin glowed with a rosy tint, and her shy, youthful face looked incredibly adorable.

Wow, a real-life anime beauty, Sasuke thought. Her faint, sweet fragrance lingered in the air.

“Sakura, what’s up?” Sasuke asked.

What came next shocked him to his core.

“Sasuke, I like you. Will you be my boyfriend?” Sakura said, her cheeks bright red as she shyly offered him a homemade meal.

This…

An invincible check-in at the start.

And now, a confession from a beautiful girl?

What a thrilling start to his new life!

In the original series, Sasuke would have likely rejected her outright.

But this wasn’t the original Sasuke.

Takahashi Haruto, now Sasuke, was anything but cold and rigid.

“Well then, Sakura, from now on, you’re my girlfriend,” Sasuke declared confidently.
