It appeared that after breaking off his arsenal of nails and stripping him of all the weapons on his person, Nanami had relaxed, thinking he lacked any means of recourse – but no.
She underestimated his Mantis Talons.
Kamakiri was able to shoot out new nails repeatedly. Sure, he had his limits – but breaking off or tearing free his nails just once was not enough to leave him weaponless!
“What have you understood?”
“Ah, I mean, I’ll talk, about our ninpo – ninpo – Ninpo –“
But Kamakiri’s cry became a battle cry –
“Mantis Talons!”
Kamakiri shot out his nails.
Unable to give them time to fully form, they were somewhat lacking in thickness, but he made sure the tips were plenty sharp. Aiming straight for Nanami, he grew all ten nails at max speed.
Giving him ten spears.
Yet –
“…”
Nanami, with a slight twist of the hips, dodged all ten of the talons. No clean break, the ten nails tore through her kimono, nearing her skin and plunging deep. At first glance, it appeared that she had moved too late, but not so – in shifting slightly, she had intentionally caught the nails in the cloth of her sleeve. By dodging him with such precision, she had barred the nails from further action. Thanks to her kimono, all ten had been taken out of service.
Of course, this was no more than a precautionary measure. In other words, she could comfortably dodge Kamakiri Maniwa’s ten nails regardless –
Thus evading his attack, Nanami jammed the talons down his throat. Their tips tore through the back of his windpipe – into the trunk of the tree behind him.
