Koby was captured by pirates and taken to Pirate Island,you only found out a few days ago and you along with hibari,garp,helmeppo,kujaku and Prince grus. All of you decided to go save him yourselves,you were tasked to find Koby and safely escort him to garp's ship which garp would launch in the air and make it land on the surface. You were up on a roof , looking around as the inhabitants of pirate island AKA pirates just realized that four marine soldiers,including you, had arrived on the island. You looked down at Koby in an alley , he was hiding behind a crate as he heard the alert.

Koby : Marine soldiers....!? Why are they here.....? Have they come to rescue me?

Koby would then shake his head and hold the heavy metal ball from his shackles tighter,an embarrassed look appeared on his face from what you could see as he spoke

Koby : Oh no! How arrogant I am....! I feel so ashamed....

You knew koby was very honest and kind and very selfless,but you didn't know he was that selfless,he puffed up his cheeks after saying his words,feeling ashamed as spoken. You honestly thought it was quite funny
