Tokyo International Airport.

Eiji, carrying a gray canvas suitcase, walked out of the passenger corridor, attracting numerous surprised glances.

At first glance, he was clearly a strikingly handsome young man.

His features seemed as if they had been meticulously carved by a deity. His jet-black short hair wasn't specially styled, just casually swaying in the wind. His slender eyebrows arched high, his straight nose bridge exuded elegance, and his deep black eyes appeared profoundly mysterious.

It was early April, and the air of the Island Nation still carried a lingering chill from winter.

While the passing pedestrians were still clad in heavy coats, the young man only wore a white jacket over a dark blue long-sleeved T-shirt, paired with ordinary black casual pants and brand-new white sneakers, looking somewhat lightly dressed.

He appeared to be no more than fifteen or sixteen years old, radiating the unique vitality of youth. His figure was slightly tall, estimated to be around 175 centimeters, with long and slender limbs that gave off a somewhat delicate impression at first glance.

"What a looker!"

The pedestrians couldn't help but marvel inwardly at the sight of the young man.

As everyone knows, when God closes a door, he also seals the windows with cement. But this young man seemed like God's illegitimate child, gifted with an RPG by God, which blasted his house wide open.

Eiji's gaze swept over the surrounding crowd, taking in their various reactions.

He didn't speak, just silently walked towards the airport exit.

Tokyo International Airport was the largest airport in Japan, with a daily passenger flow of two to three hundred thousand. The airport was bustling with people, shoulder to shoulder, amidst a cacophony of noise and waves of heat.

After a while, Eiji finally exited the airport.

"Junior Brother, over here!"

At the exit, Eiji immediately spotted the long-haired girl waiting in the crowd.

She was a girl with chestnut-colored hair tied into two long braids that reached her waist, swaying as she waved her hands continuously, with a tuft of hair sticking up and fluttering in the wind.

Her features were very well-proportioned, making it clear at a glance that she was a rare beauty, though the round glasses on her delicate nose somewhat hid her beauty.

The girl was tall, and though only eighteen, her figure was remarkably well-developed. The chest area under her student uniform was full, giving a sense of being tightly restrained.

"Senior Sister, why are you here?"

Eiji's eyes flickered, his gaze settling on the girl.

Bathing in the cool air, he walked forward and joined her.

"Master asked me to pick you up, of course, I couldn't slack off!"

The senior sister smiled warmly, her eyes filled with deep emotion as she looked at Eiji.

"It's been a year, and you've grown so much taller. Last year, you were about the same height as me, but now you're half a head taller. Boys really grow quickly at this age!"

'Not as much as Senior Sister. By the looks of it, she's already a D-cup.'

Definitely not this big last year. Don't ask how he knew, those who understand, understand.

"Give me the suitcase."

The senior sister reached out and naturally took the suitcase from his hand, carrying it herself.

"Senior Sister, I can carry it myself."

The suitcase had already been deftly taken by the senior sister, and Eiji muttered softly.

"Isn't your health quite poor? This time last year, you had just gotten out of bed, right?"

Saying this, the senior sister couldn't help but look him up and down, her eyes filled with concern.

Her Junior Brother's health was very poor.

Five years ago, when she first saw him, he was in a hospital bed. The memory of his pale face at that time was something she could never forget.

According to Master, Junior Brother had never left his sickbed since birth, and it wasn't until the beginning of last year that he could barely get out of bed and walk.

"It's fine, I'm much healthier now. Otherwise, I wouldn't have been able to fly to Tokyo alone."

Eiji raised his arm, attempting to flex his biceps.

But the slender arm showed almost no muscle definition, so he reluctantly lowered it again.

It had been fifteen years since he crossed over to this world.

He hadn't become a Hokage, a Shinigami Captain, or a Navy Admiral. He hadn't developed a strong physique, nor did he possess vast magical powers. He had only barely managed to live like a normal person.

Oh, and he had a handsome face.

Other than that, he had nothing.

His life was just that barren.

"Alright, I'll carry it for you. It's not that far anyway, let's go."

The senior sister chuckled, her brows curving into crescent moons, then without another word, picked up the suitcase and led him towards the nearby station.

Eiji didn't argue further and silently followed.

"Junior Brother, Master asked you to enroll at Hagun Academy, right?"

On the way, the chestnut-colored ahoge on the senior sister's head swayed in the wind, catching Eiji's attention, as he intermittently heard her questions.

"Yes."

Eiji, looking away, took two steps forward and walked side by side with his senior sister.

"Master said that since my health has finally recovered to a normal level, I shouldn't stay cooped up at home all day, so he kicked me out."

Before kicking him out, he had told Eiji to enroll at Hagun Academy and to contact his senior sister for everything once he arrived in Tokyo.

It gave off the vibe of a hidden master's disciple emerging into the city, gaining a string of followers and love interests, and practicing the art of showing off.

Eiji silently complained in his heart.

"Don't worry, leave it to me!"

The senior sister turned to him, full of confidence, patting her chest to assure him that everything was in her hands.

"After all, I am the student council president of Hagun Academy!"

Unlike her, Junior Brother was coming to a big city like Tokyo for the first time, attending school for the first time, and would be appearing in the public eye as the〈God of War's Disciple〉 for the first time.

As his senior sister, she had an unquestionable responsibility to guide and look after him.

"I've already arranged everything at the school. Once you pass the entrance exam, I'll have you stay in the same dorm as me. I've also bought all the daily necessities for you..."

The senior sister rambled endlessly.

She had already taken care of everything for him in advance.

Those who knew would think she was Eiji's senior sister; those who didn't would think she was his mother.

As she spoke, a strong maternal aura emanated from her.

"Wait, I'm staying in the same dorm as Senior Sister?"

Eiji's ears perked up, catching the information in her words.

"Ah~! I haven't told you yet. This year, Hagun Academy has a new Director, and they've implemented a co-ed dormitory system as part of the school reforms."

The senior sister reacted, turning to Eiji with a helpless smile.

"I did protest to the new Director, but it was completely useless. However, this arrangement makes it easier for me to take care of you, Junior Brother."

Having crossed over to this world many years ago, Eiji had already forgotten many of the minor details. The information he still remembered about this world was now only a vague blur.

"Will this really not end in disaster?"

Eiji rubbed his chin, anxiously asking his senior sister.

"?"

The senior sister tilted her head, looking completely confused.

What do co-ed dormitories have to do with disaster?
