An extra story for those who liked Nose-Gun:
-In a couple of years... (where Luffy is the Pirate King)-
"Hmm, you've gotten better," Zoro commented as Kaku scratched his nose.
"I know, I took your words to heart, but there are somethings in this world that I can't do," he sighed as he readied himself for the next blow, "I've seen that you've gotten even more arrogant."
"Thanks," Zoro grinned back, his headband was already on, "And I noticed you've changed as well."
"Is that so?" as they started a small battle with endless blows and blocking.
"Yeah, you're more..." both jumped back a couple of feets as the green-haired swordman unwavering eyes smirked.
Now, on the other side, the capped-male was awaiting the words, stronger, weaker, monstrous, weapon, machine, disgusting, words he was used to, words that he grew up with. Not was Roronoa Zoro had prepared for him.
"...Human."
A word that Kaku had forgotten about. A word that he never figured the defination about.
But for whatever reason...
It felt natural.
Maybe that's what counted.
