Tokyo International Airport.
Carrying a gray canvas suitcase, Hoshiharu walked out of the passenger corridor, drawing surprised glances.
Upon closer look, he was clearly a handsome young man.
His facial features seemed meticulously carved by a skilled artisan, full of cleverness. His short, ink-black hair was not specially groomed, just flowing straight and high in the wind. The bridge of his nose accentuated his elegance.
Especially his dark eyes, as vast as the starry sky, irresistibly drawing people in.
It was early April, and the air in the island nation was still a bit chilly from winter.
Everyone passing by was still wearing thick coats, yet the young man was only wearing a white coat with a dark blue long-sleeve shirt. His lower body wore ordinary black casual pants, and he had on new white sneakers.
He looked only about fifteen or sixteen years old, with the unique charm of youth, but he was very tall, estimated to be around 1.75 meters. His limbs were long and slender, and at first glance, he even gave the impression of being weak.
"What an extraordinary man!"
Seeing the young man's figure, the passersby couldn't help but marvel inwardly.
Hoshiharu's eyes swept over the people around him, observing all the reactions.
He didn't speak, just walked silently towards the airport exit.
Tokyo International Airport is the largest airport in Japan, with a daily passenger flow of two to three million.
After a while, Hoshiharu exited the airport.
"Junior Brother, I'm here!"
At the exit, Hoshiharu immediately saw the long-haired girl waiting amidst the crowd.
It was a girl with long brown hair tied into two long braids. The braids reached her waist and swayed as she kept waving her hand. A tuft of ahoge hair on her head still fluttered in the wind.
Her facial features were quite ordinary, and at a glance, it was clear she was a rare beauty. However, the round-framed glasses on her delicate nose somewhat masked her appearance.
The girl had a tall figure. Although she was only 18 years old, her figure was quite impressive. Her chest swelled under the student uniform, so much so that it was almost bursting.
"Senior Sister, why are you here?"
Hoshiharu's eyes moved slightly and his gaze fell on the girl.
Bathing in the cooler air, he walked forward to join the girl.
"Master asked me to come and welcome you this time, of course I couldn't ignore it!"
Senior Sister smiled very gently and looked at Hoshiharu with a sigh in her eyes.
"We haven't seen each other for a year, and Junior Brother has grown so much. Last year you were about the same height as me, but this year you're half a head taller than me. Boys really grow quickly at this age!"
'Not as well as Senior Sister.'
Visual inspection indicated a D cup.
Last year it definitely wasn't this big. Don't ask Hoshiharu how he knew.
"Let me carry that box."
Senior Sister extended her hand, naturally taking the suitcase from his hand and carrying it herself.
"Senior Sister, I can carry it myself."
The box in his hand had been taken by his Senior Sister.
"Isn't your health very poor? You could barely get out of bed at this time last year, right?"
When Senior Sister heard this, she couldn't help but look him up and down, her eyes full of concern.
Her Junior Brother's health was indeed poor.
Five years ago, the first time she saw her Junior Brother was in a hospital bed.
According to the doctor, her Junior Brother had never left the hospital bed since he was born. It was only around the beginning of last year that he could get out of bed and walk around.
"It's okay. I'm much healthier now than before, otherwise, I wouldn't have flown to Tokyo alone."
Hoshiharu raised his hand, trying to show off his biceps.
But there were almost no muscles bulging on his slender arm, so he had no choice but to lower his arm angrily.
It had been fifteen years since he traveled through time.
He hadn't become a Shinobi, Shinigami, or Admiral, he hadn't developed a strong body, he didn't have magical powers as vast as the sea, he just lived like an ordinary human.
Oh, and he had a handsome face.
Other than that, nothing.
His life was very barren.
"Alright, let me help carry it. It's not far anyway, let's go."
Senior Sister chuckled, then she took the suitcase without any explanation and carried it to the nearest station.
Hoshiharu didn't argue and followed quietly.
"Junior Brother, Master asked you to come to Hagun Academy to enroll, right?"
On the way, the chestnut hair on Senior Sister's head swayed in the wind, attracting Hoshiharu's attention, and he occasionally heard her questions.
"That's right."
Hoshiharu shifted his gaze, took two steps forward, and walked alongside his Senior Sister.
"Master said that my body finally returned to normal and I shouldn't stay at home all day, so he sent me away."
Before sending him away, Master had told Hoshiharu to enroll in Hagun Academy and contact his Senior Sister for anything after arriving in Tokyo.
It felt like a disciple of a hidden master in urban literature going out, gaining a series of beautiful younger sisters and brothers, and practicing the art of showing off.
Hoshiharu complained inwardly.
"Don't worry, leave this matter to me!"
Senior Sister turned around, looked at him confidently, and patted her chest to declare that she would handle everything for him.
"After all, I am also the student council president of Hagun Academy!"
Unlike her, this was the first time her Junior Brother had come to a big city like Tokyo, the first time going to school, and also the first time appearing in public as the disciple of the God of War.
As Senior Sister, she had an undeniable responsibility in guiding and caring for her Junior Brother.
"I have already made arrangements at the school. As long as you pass the entrance exam, I'll let you stay in the dormitory with me. I have also bought all the daily necessities for you..."
Senior Sister spoke casually.
She had already arranged everything for him beforehand.
Those who knew thought she was Hoshiharu's Senior Sister, and those who didn't would think she was his mother.
As she said this, Senior Sister always exuded a strong sense of motherhood.
"Wait a minute, am I and Senior Sister staying in the same dormitory?"
Hoshiharu's ears twitched and he caught the information in Senior Sister's words.
"Ah~! I haven't told you yet. Hagun Academy has a new director this year, and he happened to be implementing school reforms and applying a mixed dormitory system."
Senior Sister reacted and turned to look at Hoshiharu, smiling helplessly.
"I also protested to the new director, but it was of no use at all. However, this just makes it easier for me to take care of Junior Brother."
Hoshiharu had long forgotten many details after years of time travel. What remained in his mind now was just vague information about this world.
"Is it really not going to kill anyone?"
Hoshiharu rubbed his chin and asked her anxiously.
"?"
Senior Sister tilted her head, looking puzzled.
What did mixed dormitory housing between boys and girls have to do with human life?
