“Oh, and another thing.”
Nanami held up her right hand and flicker her thumb smartly at Mitsubachi.
“What did you call it, the Blunderbuzz?”
“How…”
Considering the caltrop lodged into his shoulder – the time had passed for asking questions and being surprised by the answers. As should be clear by now, Nanami dodged Mitsubachi’s longsword almost instananeously before countering – with none other than the Blunderbuzz!
“What, so you had a caltrop all along – conveniently enough? Did I just miss the part where they told us you have some on you?”
“You gave them to me – both of them.”
Nanami stopped flicking her thumb and showed him her kimono. The caltrops had torn through the fabric – but only one was there.
The other caltrop, the first Mitsubachi had unleashed, was gone.
“This Blunderbuzz – it’s great that you can attack from so far away, but it’s too bad that with each attack, you give your enemy your ammo.”
“Wha… B-But! Once they break skin, they should be almost impossible to remove! What about the barb –“
“You see…”
This time Nanami showed him her left hand.
Its nails – were much longer than they should be.
Almost like blades.
Mantis Talons –
“I gouged it free, skin and all.”
“…!”
Mitsubachi’s head began to spin.
The shock of hearing that Nanami had gouged into her own flesh was incredible enough – but there was more. If this was the same caltrop that he threw at her, then it was poisoned, and now that toxin was traveling through his body!
“H-How could… How did… When you only saw the Blunderbuzz – me, do it once…”
“Okay – not like this is a compliment, but that is not an easy move. I was aiming for the center of your back, but it strayed way up and to the right… and even this close, it had less force than I wanted. Surprisingly hard to do. I wish I could have seen it twice.”
