Demon Slayer: The Strings of Infinity

I became Muzan’s last trump card, codenamed Upper Rank Zero.

He ordered me to deal a fatal blow to the Demon Slayer Corps during the decisive battle at Infinity Castle.

But as soon as the battle began, I linked the minds of every Corps member.

“Everyone, listen up. I’m your new commander.”

“Akaza’s weak point is the old wound on the side of his neck. Shinobu Kocho, don’t charge in and get yourself killed. Giyu Tomioka, dodge three steps to the right!”

“Today, we’ll avenge Big Brother Rengoku together!”

So there I was in Muzan’s lair, with a full map view, directing his mortal enemies as they wiped out every one of his Upper Ranks.

That is, until Muzan came charging at me, eyes bloodshot.

I laughed and spoke over the public channel. “Boss, surprised?”

“I flipped your chessboard.”
