(Extra Information)

What Is the Black Agency?

The Black Agency was a covert task force initiated through a secret alliance between the Prime Minister of Japan and Kaito Toshio. Founded with the ambitious goal of achieving global peace through Project Inyo, the agency operated in the shadows—specializing in espionage, supernatural defense, and advanced technological warfare. Under Kaito’s leadership, it grew from a peacekeeping initiative into a powerful organization with influence stretching across nations and realities.

Who is Kaito Toshio?

Kaito Toshio is the central protagonist of The Legacy of Mr. Spades—a complex antihero shaped by loss, betrayal, and unrelenting ambition. Once a brilliant strategist chosen by the Prime Minister of Japan to lead the Black Agency and carry out Project Inyo—a mission for global peace—Kaito's life took a darker turn after the deaths of his parents and wife.

Stricken by grief and driven by vengeance, he struck a forbidden pact with the demon Zathathan, gaining immortality and supernatural powers. As his ideals twisted over time, Kaito evolved from a symbol of hope into a ruler of shadows—conquering Japan, dismantling corrupt powers, and later reshaping the multiverse itself. Though feared by many, he remains a tragic figure—a man who sought peace but was consumed by the price of power.

My oc's Origin story: How He was made.

The story of Kaito Toshio, also known as Mr. Spades, began in my childhood, back when his first form was known simply as Mr. Black and White, created in MeepCity on Roblox. From there, his identity evolved through various phases: first adapted into Mr. Ying Yang during Yandere Simulator roleplays on roblox, and later refined into the masked persona Mr. Black Spades, eventually becoming the definitive Mr. Spades.

But despite the passion I poured into him, my OC was often overlooked—ignored by the very communities I tried to share him with. Tired of being dismissed, I stepped away from Roblox and chose a new path: storytelling.

What began as a school project grew into something more—a full book series built on lore, purpose, and personal growth. That’s how Kaito Toshio was truly born—not just as a character, but as a reflection of perseverance.

Now, I’m turning that story into a manga series, hoping that the world will finally see him not just as my creation, but as a character worth remembering in the anime world.

Yatagiato Ayashi

"I was never the one on the battlefield.

Not the one giving orders or drawing lines on a war map.

I was the one waiting at the door.

The one who brewed tea during strategy meetings…

Who kept the house warm while Kaito carried the weapons of a broken world.

Some called me just a housewife.

But I was more than that.

I was his calm.

His shadow.

His reminder that he was still human, even when the world tried to make him a weapon.

And now, I see our son walking the same path.

Hayato is strong—stronger than he knows.

But strength isn’t just fire and fury…

It’s knowing when to listen. When to love. When to rest.

I won’t fight beside him.

But I will always be behind him.

Guiding. Watching. Believing.

Because sometimes, the quietest voices build the loudest legacies."

Hayato toshio

"They call him a legend.

I just called him Dad.

The world saw a conqueror. A genius. A god.

I saw a man who never slept… because peace was never promised.

He built an empire from shadows, carved justice with fire.

But fire burns—

And I carry the scars of every choice he made.

I’m not here to worship his footsteps.

I’m not here to wear his mask.

I carry his blood, not his chains.

And if legacy means becoming him…

Then I’ll rewrite what legacy means.

Not as the son of Kaito Toshio—

But as the one who chose a different light."
