My roommate turns out to be the heiress of a triad!

When young Kenji first met the eldest daughter of the main family, he knew she was the person he would do anything to protect in his life.

"Kenji, come here quickly and greet the young lady."

Back then, Grandpa's voice wasn't as aged as it is now, and there were hardly any wrinkles between his brows.

He stood ramrod straight, respectfully standing next to a little girl much shorter than him, who was waving to him.

The little girl was just up to her grandfather's waist and was wearing a light blue floral dress.

Her short, jet-black hair was styled into a bob, with a crimson ribbon pinned to one side of her small head.

Because her ancestors had foreign blood, the girl's pupils were a clear, light green, like jewels, which deeply attracted him.

Just as the little guy was engrossed in watching, the girl, wearing brown leather shoes decorated with bows, leaped down from the wooden veranda of the Japanese garden and ran towards him with a clattering sound.

Sometimes the pebbles used to fill the gaps between the stone slabs are blown away by the wind, and people can easily trip over the slabs if they are not careful.

There was a thud, the sound of the toe of a little leather shoe hitting the crack between the stone slabs.

The little girl, having lost her balance, is falling at a speed visible to the naked eye.

Normally, this process would only take a moment.

This extremely short period of time wasn't even enough for an adult within a meter to make a corrective action, let alone the fact that the little girl had already run far away.

But for some reason, at that time, Kenji Koyama felt that the flow of time suddenly became very slow, so slow that he could see the afterimage left by the little girl as she slowly fell down.

The hands, feet, and even the whole body seemed to have developed self-awareness.

By the time his brain reacted, he had already pounced and caught the little girl safely.

"Moyu!"

Wearing a colorful tomesleeved shirt, the young lady who had been kneeling on the veranda was terrified and called out her beloved daughter's name.

At that time, Kenji Koyama did not understand the meaning of the two characters "Moyu". He just thought the name sounded nice and immediately remembered the name of the girl in his arms.

Her fall startled everyone around her, but she acted as if nothing had happened, forcing a sweet, innocent smile as she turned to the adults to show that she was alright.

Then, with cold sweat beading on her forehead from the shock, she took his hand and thanked Kenji Koyama with a smile.

「ありがとうね! My knight.」

"wheat……"

"It's My knight! My knight."

He later learned that the girl he had just met, named Kujo Mayu, who always liked to push herself, called him "my knight."

A knight?

Perhaps the children who separate from the family should assume this role.

According to tradition, the Kujo family, which has yakuza backgrounds, would have their daughters homeschooled.

The reason for bringing Kenji Koyama to the main family was that he was about the same age as Mayu Kujo and could accompany her during the first few years of her schooling, so that Mayu wouldn't be too lonely and lose interest in learning.

Therefore, when Mayu Kujo was receiving education from her tutor, Kenji Koyama would also listen in on the proceedings.

Leaving aside the regular primary school curriculum.

Tea ceremony, flower arrangement, archery, piano, etiquette—Kujo Mayu's days are packed with activities.

Kenji Koyama never saw her do anything that other children her age were doing.

For example, they would go to and from school with their backpacks, or laugh and play loudly in the children's park.

During a flower arranging class, as they walked along the wooden corridor, Kenji Koyama was so engrossed in looking at the magnificent furisode he had made specifically for her that he blurted out these words as if possessed.

"Moyu-chan always lives in a grand house with a large courtyard and spacious rooms."

Just like Princess Hime in the story.

Such words should not have come from a child who has separated from the family.

To his surprise, she shook her head violently upon hearing this, the tassels on her hairpin swaying as if they mirrored his heart at that moment.

"Really? Kenji, you're so good with words. If I'm a princess, then you're my samurai-sama who protects me."

A young person's heart is like a lake, seemingly flat and calm, but in reality, a single stone can cause ripples.

To this day, Kenji Koyama has never seen such a beautiful woman again.

Mr. Kujo would occasionally take his family to a villa in the mountains or by the sea for vacation. After returning, Mayu Kujo would always complain to him, saying that it didn't really matter where they went, because they still had to study.

However, since she only gets to see her busy father during those few days each year, Xiao Moyou always smiles contentedly and shares with him the things she learned while on vacation with him.

Before she knew it, she had reached the age of starting junior high school, and Kujo Mayu's parents argued about how to educate her in the next stage.

Her father advocated that she go to school like other children her age and receive a regular, modern education, while her mother advocated the traditional education model of the Kujo family and that she continue to study at home.

Both sides held their own opinions.

When the argument reached a stalemate, it was the still-living grandfather of Mayu Kujo who made the final decision to let her go to school.

Kenji Koyama still remembers how excited Mayu Kujo was when she learned that she was going to go to school.

"Kenji, I've heard there are a lot of interesting clubs at school."

Should I join any clubs or organizations then?

"Kenji, I heard that your best friends at school go to karaoke together after school."

Should we go together next time?

"Kenji, I heard from Grandpa that when you go to school, you'll have to compete with others for rankings in your studies."

Can you keep up with me?

This should have been something to be happy for her.

But Kenji Koyama was not happy at all.

Because he knew that once he left this home, this Japanese garden where they had lived under the same roof for six years, would no longer be his exclusive possession.

With such outstanding looks and excellence in every aspect, how could she not attract attention?

And indeed, it turned out just as he had guessed.

After entering middle school, Mayu Kujo became very popular among the boys.

So many people wanted to confess their feelings to her that he couldn't stop them all.

He even became one of the many people confessing their love to him.

Until that day, he received this reply.

"Kenji, aren't you my knight, my samurai?"

It was only then that Kenji Koyama realized that during the six years they had spent together, he had only been treated as an older brother by Mayu Kujo, without any other feelings involved.

My mission is to silently protect her.

That makes sense.

It is a great honor for the children of the separated family to serve the main family, so how can they expect anything else?

He just couldn't understand why his young mistress would be so fond of this kind of man.

In Koyama Kenji's eyes, Sugawara Ryoichi, who was sneaking his head out from behind Kujo Mayu, looked like a new recruit to a gang leader's gang, lacking any courage or responsibility.

He was timid and cowardly, and had absolutely no manliness whatsoever.

The two confirmed their relationship without the girl even realizing it, and the news spread like wildfire, becoming known to almost the entire school within two days of the young lady running away from home.

Based on his understanding of the young lady, he was certain that she had done this intentionally.

After all, she is a princess of the Yakuza.

She had long since learned most of that man's methods of manipulating others and controlling situations.

As for the purpose, it's probably only that.
