Neon Bunkyo District, inside a somewhat old one-family building.

Wearing a short-sleeved sportswear, Nakano Mayu is holding one hand on the floor in the living room, doing push-ups in a standard posture.

Sweat dripped from his body, flowing down his body like a cheetah.

"Nine hundred and ninety-eight!"

"nine hundred ninety-nine!"

"one thousand!"

"call..."

After counting to a thousand, he took a deep breath and fell down on the light pink yoga mat under him...

[Ding, complete the weekly task, physical strength 1]

A translucent prompt suddenly appeared in front of his eyes.

This is the system he acquired after traveling to Tokyo with an unusual style.

Two years ago, when he had just crossed over from the Yan Kingdom and turned into a Tokyo boy whose parents were dead, had a sister and a house, he accidentally discovered that he could bend the iron stairs with one kick, and thought he was from this new world.

Superman.

But when he turned around, he saw his sister, who was just over fourteen years old and about 1.5 meters tall and slender, carrying two bags of rice weighing 50kg on each shoulder, walking as fast as flying...

After he paid for the repair fee for his neighbor's aunt's stairs that made a rattling sound with his fist, he knew that something might not be right in this world...

Then it was revealed based on the information he found online.

One day twenty years ago, everyone felt that the air between heaven and earth suddenly became fresher. From that day on, human bodies also underwent subtle changes and became stronger. However, the physiques of other animals were not that big.

Change.

The physical fitness of ordinary people is to the extent that they can catch a tiger with their bare hands and fight a crocodile with both hands.

Human beings have truly become the strongest creatures in terms of strength alone.

But no matter how human beings' physical fitness develops and improves, the order of this world will still remain the same...

After all, the world in which everyone has grown up is not much different from the world before when everyone did not grow up...

Students still have to go to school, and workers still have to work overtime...

When crossing the road, you still have to look at the traffic lights. In the past, I was afraid of being hit by a car, but now I am afraid that if I accidentally crash the car, I won't be able to afford the compensation...

"Nini~ Go wash up and come have breakfast..."

That was his sister, Nanako Nakano, who had been dependent on each other after her parents died...

"good..."

Nakano Mayu came to the bathroom and quickly washed away the sweat stains on his body.

He casually put on the washed and ironed school uniform that his sister had placed on the shelf, and picked up the hair dryer at the same time.

He blew on his refreshing dick and looked in the mirror.

The boy in the mirror, whose originally well-proportioned and toned six-pack abs were now completely covered up under his white shirt, made his figure look a bit thin.

The angular face is slightly three-dimensional, giving his temperament a sense of perseverance that is rare among young people.

What's most striking is the clear black and white eyes, which seem to have stars flowing through them, making them look both deep and mysterious.

If you accidentally look at it for too long, you will easily fall into it.

It was a handsome young man...

"Tsk, why are you so handsome?"

He thought about the various love letters that he had often opened the cabinet and scattered all over the floor over the years, which often took him a long time to sort out, and he complained with some annoyance.

"Nini, the rice is getting cold~"

"coming..."

When he came out, the originally wet yoga mat had been washed and dried in the small yard by his sister, and breakfast had been placed on the dining table.

My sister's face looked a little redder than before, like a freshly peeled egg, white and rosy, with a cute and well-behaved expression.

But he recently heard from his neighbors that his sister's behavior in middle school was not this well-behaved.

It seems that she was given the nickname "Unparalleled Sword Princess" by her classmates. Giving this kind of middle school nickname is a specialty of the entire neon society, and is not just something that middle school students do.

"Nini?"

He looked away from his younger sister, who was looking at him with some confusion, and did not ask her about what happened at school.

After all, adolescent girls also have many little secrets of their own...

...

Because Neon basically implements the meal sharing system, their family usually eats separately.

In front of Nakano Mayu's seat were two freshly fried fresh ocean fish, five poached eggs, three grilled sausages, a large bowl of miso soup and a bowl of rice.

His sister's appetite is less than half of his, but it is far more than the average breakfast appetite of girls in previous lives...

In the past, he felt a little bit magical every time he saw how much he ate, but he could basically eat cleanly. Over time, he gradually got used to it...

"Nini, when I was practicing my sword the day before yesterday, I also cut out the sword energy ~ a full ten centimeters!"

The slender girl wiped the water stains on her hands with the apron in front of her and said to him happily.

"oh?"

Nakano Mayu looked up and saw the proud expression on his sister's fair and smooth face, with a matching surprised smile on her face.

"Nanako is great, but remember what my brother told you. The Nakano Itto-ryu swordsmanship that our family has passed down can produce sword energy. You must remember to keep it a secret and don't tell anyone except your brother..."

"Oh...Brother, how many times have you told me that I won't tell anyone else. After all, I have never heard of a similar situation. If I are caught and sliced ​​for research, our Nakano family will be in trouble!"

When Nakano Nanako heard the warning, although her interest became low, she still nodded to show that she had listened to his warning.

"Hehe, Nanako is so good..."

After all, he didn't know whether there were many people in the world with extraordinary powers like him and his sister, or whether it was just him and his sister who had them.

If it's the former, it doesn't matter. Maybe he and his sister are just fledglings in the eyes of those real masters.

But if it's the latter, then you have to be very careful...

Nakano Mayu raised his hand and pinched his sister's soft face with some baby fat, and suddenly a bitter smile appeared on his face.

"Nini! How many times have I told you! Nanako is no longer a child, and you can no longer pinch Nanako's face!"

The girl felt her brother's kneading, and she showed an expression of enjoyment at first. Then she thought of something and pushed his palm away with a pair of cute little tiger teeth.

"Yes Yes Yes..."

He followed his sister and took his hand back, and at the same time suppressed the bitter smile on his face.

If this system had not appeared, his future would not have been bright, but with the high insurance money of his predecessor's parents and the inheritance of this house in Bunkyo District, Tokyo, at least he and his sister's tuition and fees would have been covered.

Basic food and clothing are still barely bearable.

But ever since the system appeared, he felt as if a high-speed rotating chainsaw was hanging above his head, and it would fall down at any time.

It's not because this is some strange system whose goal is to get rid of the host.

It's because of what's displayed on the system.

【Nakano Mayu】

【Age:17(18)】

[Stamina: 31]

[Intelligence: 15]

【Charm:25】

[Note, the average of the three attributes for ordinary people is 10]

[Item: None]

[Skills: Ancient Swordsmanship: Nakano One-sword Style lv2 Cooking Skills: lv1]

[Points: 0]

Yes, that's what's in the parentheses after his actual age.

He is about to celebrate his 18th birthday in half a year. The upper age limit at the back is marked as 18...

Just focus on the age brackets and it will become clear:

[This is the current upper age limit of the host]

Such a passage...

In other words, he, Nakano Maysuke, is the ultimate macho man who can slash seven swords in one second, crush a tiger to death with one hand, and practice swordplay all night long without getting tired!

Can only live until 18 years old!!
