How could she call it nothing? That simply couldn’t be. Even if she was a genius of unparalleled, unmentionable ability… poison and illness will take down even the greatest! Indeed, after absorbing but a single caltrop’s share, Mitsubachi was in such pain he felt his body being torn apart!
“Torn apart…” said Nanami, using the nails of her left hand to gouge out the second caltrop, skin and all.
Gouging her nails into her own flesh.
No change to her expression whatsoever.
“That’s nothing – I feel that way every day.”
“…”
“Like you said, the poison worked wonders as a painkiller – pain and suffering are old friends of mine by now. A little more can’t hurt – literally. Even if it does itch a little.”
Nanami Yasuri – a woman whos hould never have been born.
She’d done nothing to reach the top.
Skills other martial artists acquired only after coughing up their share of blood were hers to embody, through no toil whatsoever.
Her strength broke the mold.
Her strength broke the rules.
Surpassing – what we know as strength.
Which is why the gods punished her.
For being far too superior – they saddled her body with a billion maladies. Her body was gratuitously packed with these afflictions, each plenty fatal on its own – and inviting a whole suite of complications that made her life gratuitously excruciating.
Yet her innate genius rejected the maladies.
Rejected poison, and illness.
Through all the pain and suffering, even on the verge of death, her body refused to die. She could not get any weaker, and was too feeble to function – but held out, living on the brink of death.
She should have died by now.
She should not – have been alive.
Her body possessed an outsize capacity to heal, keeping her billion maladies at bay.
The gouges in her belly skin – would soon be gone without a trace.
