Sign-in System

Konoha, Year 59!

A small grove!

A twelve-year-old boy with black hair lay curled up on the ground.

He opened his eyes, only to see towering trees and scattered rocks.

"Where am I?"

"Ugh..."

As soon as the boy stretched, pain shot through his body. He sucked in a sharp breath.

"What on earth is going on? I've somehow ended up here, and my whole body hurts like hell!"

He endured the pain, leaned against the tree trunk behind him, and sat up.

Just then, unfamiliar memories flooded his mind, and his head spun.

Ten minutes later, the dizziness passed, and he came to his senses.

"So this bizarre transmigration really happened just like that!"

The boy was utterly bewildered. He clearly hadn't expected that he would actually transmigrate.

Before he came here, he had been playing an idle fishing game. This time, he had fished up an email.

"Congratulations, player! You have obtained a mysterious system through fishing. Would you like to enter the world of Naruto with it?"

On a whim, the boy chose to enter. Everything went black, and when he opened his eyes again, he was here.

As the memories merged, he also learned a few things about himself.

His body belonged to Uchiha Mirai, one of the Uchiha Clan's surviving orphans.

His parents and family had all been killed by Uchiha Itachi, leaving Uchiha Mirai with only a house and a little money.

Most importantly, he was often competing with Uzumaki Naruto for last place at the Ninja Academy.

At the thought, Mirai couldn't help feeling speechless.

"But I was told I'd be bringing a mysterious system with me. Where is it?"

Uchiha Mirai had fully accepted the fact that he had transmigrated.

But since he had arrived without seeing any system, he couldn't help wondering what had happened to it.

"Ding! Sign-in System binding in progress..."

"Ding! Sign-in System successfully bound!"

The system's sudden prompt startled Mirai.

"Ding! The host can use the Sign-in System to check in once a day and receive a random reward!"

"Ding! Would you like to check in?"

The string of system prompts helped Mirai understand how it worked.

Excitement!

Thrill!

Mirai was over the moon. He hurriedly started his first check-in of the day.

"Check in!"

"Ding! Congratulations, host! You have received the Initial Sage Body!"

A cool current flowed through his body, and Mirai felt the pain gradually begin to fade.

The current made a circuit through his body, then disappeared.

Thanks to it, his aching body recovered almost completely.

"Hyah!"

Feeling his body recover, Mirai got to his feet and stretched.

"As expected of the Sage Body. My body's self-healing and chakra recovery are more than twice as fast as before, and my chakra reserves have nearly tripled."

Feeling the power of the Sage Body, Mirai couldn't help marveling at it.

"Sasuke, just you wait. We'll settle the score from today..."

As it turned out, Sasuke was the reason Mirai had been lying there. Sasuke thought Uchiha Mirai was too weak and was disgracing the Uchiha Clan, so he had beaten Mirai to vent his anger.

After returning home, Mirai grabbed a quick bite to eat, then lay down and fell asleep.

He didn't wake up until the next morning.

The moment he got up, before even opening his eyes, Mirai checked in with the system.

"Ding! Congratulations, host! You have received the Three-Tomoe Sharingan!"

"Wakakaka!"

Mirai's eyes flew open. The surprise had come out of nowhere.

He hurried to the mirror and stared at the reflection of his Sharingan.

His eyes were red, with black pupils. Three tomoe encircled each pupil in a triangular pattern.

"So this is the Three-Tomoe Sharingan. It looks so cool!"

After admiring it for a while, Mirai put his Sharingan away.

He quickly brushed his teeth and washed his face, then took his money and headed out.

Mirai made his way to Ichiraku Ramen.

"Boss, one bowl of Tonkotsu Ramen!"

Sitting at a table in Ichiraku Ramen, Mirai called out to the owner.

The owner heard his order and replied while busy making the ramen, "Coming right up! Just a moment!"

A little while later, a steaming bowl of ramen was set in front of Mirai.

"Your Tonkotsu Ramen!"

"Oh, it's Mirai! You're early today!"

Teuchi brought the ramen over himself and only then realized Mirai was the one who had ordered it.

"I am a little early today!"

"Take your time. Just call if you want more!"

"Okay!"

Mirai picked up the bowl of Tonkotsu Ramen and tried a bite, then wolfed it down.

No wonder Ichiraku Ramen was so famous in Naruto. It really was delicious.

He ate three bowls in all before finally leaving, completely satisfied.

Ninja Academy.

Mirai walked into the classroom as usual and sat down at his desk.

"Good morning, Hinata!"

"G-Good morning, Mirai-kun..."

Hinata looked up and shyly answered him.

"Hehe!"

Seeing Hinata as a little girl made Mirai happy.

Hinata had been adorable even as a child. When he watched Naruto, he'd been very fond of her younger self.

Of course, he liked the grown-up Hinata just as much.

After all, grown-up Hinata had an excellent figure and looks, along with plenty of other fine qualities.

Looking at Hinata now, Mirai found her cuter and cuter. In the end, he couldn't resist reaching out and ruffling her hair.

"Mm..."

Hinata had been shy since she was little. When Mirai suddenly patted her head, her face turned bright red.

Even so, she didn't try to resist.

From his memories, Mirai knew that although his body's original owner had been timid, he had also been quite righteous.

Once, by chance, he had seen Hinata being bullied as a child and stepped in to help her. That was how the two of them had become close.

Now, that bond had been passed on to Mirai.

Just then, a blond boy with whisker-like marks on his face came through the classroom door.

"Morning, Mirai!"

"Morning, Naruto!"

After greeting him, Uzumaki Naruto darted toward Kiba's seat at the back.

The two of them started playing around there.

"Sasuke's here! Sasuke's here..."

"Sasuke! Sasuke-kun...!"

"Sasuke's so handsome!"

"Sasuke-kun is the most handsome!"

The lovestruck girls in the classroom started swooning as soon as Sasuke walked in with a cold expression.

Sasuke acted as if he hadn't noticed their adoration and went straight to the seat in the corner of the classroom.
