“Kyotoryu – Tampopo.”
Before any sound could leave his lips, Nanami’s spear hand pierced his beating heart. In a single instantaneous motion, coming without warning – she’d drawn in the hand gripping his ninja garb to facilitate her spear hand’s rending encounter with the left side of his chest.
She could do without a wind-up or any other prefatory movements.
She was freeform, this was Form Zero – the Ichijiku.
The two of them fell together to the ground.
Harlequin Butterfly thusly interrupted, they made a violent landing. The impact made Nanami wince –
"N-No way..."
Hacking up phlegmatic blood, Chocho regarded Nanami with utter disbelief.
Shocked at her ability to emulate his Harlequin Butterfly? Nos so.
No, quite simply – her spear hand stunned him cold.
"No way a hand – can pierce through someone's heart... Bullshit, unbelievable. Not only that, my chains..."
Nanami had speared through the chains wrapped around his body as protection – especially for his heart. Even the shard of the Blood Crystal, a remnant of his late friend Kamakiri, which Chocho had slipped into his costume as a last line of defense – was shattered.
Swordless kenpo.
A spear hand driven like a true katana, only more menacing and destructive.
This was the Kyotoryu!
As if reading what was on his mind from his face, Nanami withdrew her spear hand from his ribcage – and let him see her gory fingers.
"The Tampopo is a grappling move, a normal spear hand unleashed while you are pulling in the opponent. And when I say normal, I mean normal. It might be able to break flesh, but common sense dictates that it could never go all the way through – unless maybe you're as strong as Shichika. What you just witnessed, I learned from your friend Kamakiri."
If you looked closely.
Nanami's fingertips – were sharp and pointy.
Nay, not her fingers, but her fingernails.
They had grown into talons.
