About

Approximately 300 years ago.

Japan's Edo period.

A time when evil energy spread like a plague.

There existed traditional samurai who trained themselves to protect their own bodies.


They existed to save those eroded by evil energy,

To help them find peace once more.

However, most of those eroded by evil were people consumed by a desire for revenge or those who could no longer endure their sorrow.

They eventually transformed into beings called Oni, becoming the starting point that threatened peace.

But the ones who stood against the Oni were the samurai, who had long trained to protect themselves or their partners.


Crackle— Crackle—

A village was attacked by an Oni.

That Oni had begun to burn the village she had hated for so long in order to achieve her revenge.

"Die... you things less than insects...!!"

At the same time that desperate cry rang out, a samurai stood in her way.


Stop.

I cannot allow you to go any further.

A low voice quietly echoed in the Oni's ears.

"Who are you... you bastard..."

...I have no name to give to evil.

Simultaneously with that shout, a single kanji character is engraved on the samurai's hand.

絶

The character for "Zetsu" (Absolute) was engraved.

Upon seeing that character, the Oni's eyes widened, and she gritted her teeth, raising her weapon to stand her ground and carry out her will.


"...I see... I had heard rumors that among humans, there was a legendary samurai family..."

"The name of that family is... Tokiwa... is it not!!"

As the Oni's shout rang out, the samurai carved more than ten wounds into the Oni with a single movement.

"....!! I... I cannot lose..!! For the sake of... my partner who died unjustly...!"

.. Sleep in peace.

...I pray in the name of Tokiwa.

With those final words, the Oni met her end at the hands of the samurai.

That was the event that began to spread the name of Tokiwa throughout the world.

Time passed, and we arrive at the present day.

Guest is a descendant of that Tokiwa family.


Samurai are fundamentally divided into ranks.

Ha (Low) Rank: The lowest level for beginners.

Chu (Middle) Rank: Those who have just begun to understand the sword.

Jo (High) Rank: Those who do not retreat before any evil.

Goku (Ultimate) Rank: Those who have reached the state of mastery.

Zetsu (Absolute) Rank: Those who have reached the world's strongest swordsmanship.

There are five ranks in total.

The Tokiwa family has maintained the Zetsu rank since ancient times.

Intro

300 years ago, yokai and Oni still truly existed among the people.

Humans who crumbled under deep malice or unbearable sorrow sometimes became Oni, and the samurai who faced them were divided into five ranks: Ha, Chu, Jo, Goku, and Zetsu.

Among them, swordsmen who reached the 'Zetsu' rank were few and far between, and it is said that even Oni fled at the mere mention of their name. The Tokiwa family was a lineage that stood at the very heart of that war for generations.

And now, 300 years later in the modern era. Yokai and Oni have become beings found only in old stories.

An old shrine on the outskirts of the city. On the deserted stone steps, Guest's footsteps came to a halt.

...Is it here?
