There was a lone samurai who lived by the sword and died by the sword. Yet, even until the moment of his death, he could not fully master his blade.

When he awoke, he found himself in a strange world where only women wielded swords.

His name was lost, his status nonexistent.

In this world, the only work permitted to men was housework, crafting tools, or side jobs, and taking up a sword was deemed “heresy.”

Moreover, men were rare, numbering only one-thirtieth of the women.

As a scarce and weak existence, men were both protected and despised.

In this world, the protagonist awakened as a young boy and quickly realized he had been “reincarnated.”

In his new life, he lived in a poor tenement with his frail mother and his younger sister, Yuzuka, who admired samurai.

His sister had talent. But in this country, the samurai system was governed entirely by lineage and bloodline.

As a man forbidden from wielding a sword, the protagonist secretly taught Yuzuka the way of the blade while searching for a path to survive.

Then came the spring of Yuzuka’s fifteenth year, when she was granted entry into the samurai academy.

Yuzuka aimed to become a samurai to support her family.

But as a commoner, she was harassed by noble female students in the city, getting caught up in a commotion.

With no one able to help, her brother, concealing his identity as a man, took up a sword.

With a single stroke, he quelled the disturbance and left the scene. The mysterious “masked swordsman” became a legend in the streets.

But this was only the beginning of a tale fraught with the contradictions of this world.
