The Itezoras probably never knew what hit them.
Her arrival had upended their environs far swifter than an avalanche – precise, oh so precise, and devastating, oh so devastating – it blew through every member of the House of Itezora.
The Itezoras’ monstrous strength? Irrelevant.
Old and young, men and women and children.
The Itezoras – eighteen families and forty-six individuals, not counting Konayuki.
Every life was taken.
Without mercy.
Slaying total amateurs and seasoned veterans alike.
As if she were – a sword incarnate.
None of them could comprehend it, much less stop it, but one thing was clear – a cold and fleeting comfort.
At least they knew why she was here.
The Mutant Blade of Kiki Shikizaki – Soto the Twin.
The Itezoras were veritable sheaths, safeguarding the Twin throughout the Age of Warring States, not even surrendering the sword to the Old Shogun.
But once the sheaths were splintered, she picked up Soto the Twin, using the monstrous strength that she had gleaned whilst battling the Itezoras.
“Not the one,” she said.
Astouding – this was a Mutant Blade, one of the masterworks of Kiki Shikizaki, worth enough to buy a country, and she was being picky.
“I can’t use the Harlequin Butterfly, or this monstrous strength for long stretches… This thing will drag me down. It’s not too pretty, either. Not the sword for me. That’s fine. I’ll just leave it somewhere obvious so Shichika can find it. Anyway, I’m glad I fought them all at once. That made it easy. I would have lost if I’d taken them on one by one – I hope things work out like that again.”
