Right after leaving thriller bark, Luffy sneaks up on y/n. Y/n felt something roughly placed on their head, they took it off, it was a hat, it was similar to aces but with a red ribbon on it like luffys. "Shishish! There you go y/n! Now you ace and I all have cool hats! I hope you like it! I was gonna give it to you on your birthday but I didn't want to wait! And I don't know your birthday. Huh!? Why are you crying! Did I do something wrong please don't cry." Luffy had never seen y/n cry ever and was panicking . "Nothings wrong Luffy *sniff* I'm just so happy! I'm so happy I'm apart of this crew and that you and ace are my brothers! I never wanna leave! I'm just so happy!" Luffy wrapped his arms around y/n acouple times and picked them up. "You should be happy! You're the best! You're so strong and brave! We're gonna adventure forever, just you wait! And one day I'll be the pirate king!" Y/n nodded. "Ya! And I'll be right by your side the whole way!"

When y/n had met hachi on the safety of the sunny they pounced on him, looking at his forehead. "You were a... a sun pirate!" Y/n cheered shaking all of the octo-mans hands. "I'm y/n a friend of Jimbei, it's so nice to meet you!" "You know Jimbei? Well anyone who is a friend of Jimbei is plenty good in my book!" Zoro and Sanji watches on in confusion, when meeting humans y/n usually keeps to themself but they're so socail with fishmen it would seem. The young pirate and the fishman talked all the way to sabody. Of course when meeting and talking y/n keeps on there mask. When they reach sabody, y/n follows after Luffy, knowing of the dangers on the island.

After saying goodbye to Nami and Robin
They soon came across a pirate with a collar around his neck, he was begging saying he just wanted to go back home, the crew watched in horror. Before anyone could stop them y/n was already infront of the man. "P-please help me! I have a family. -!" Y/n jumped up ripping the collar off throwing it into the sky as it exploded. A cloud quickly picked up the once slave and moved him far out of sight. Y/n ran back to the fishman hiding behind him. A few celestial dragons came by "who helped the slave!" Everyone but the celestial dragons could feel the killer intent y/n had, it scarred any would be snitch's into silence, y/n hid behind hachi so they wouldn't have to bow to the celestial dragons. Once they pasted everyone took a break on a large root. "Y/n... what were you thinking. I thought you would know better! You know a celestial dragon can call an admiral here don't you?" Hachi spoke The group looked at y/n in shock. The masked swordsman shook in there spot. "I'm well aware of what could of happened. But I wasn't gonna let that man continue to be a slave. I've done it before, more than dozens of times. I know what happens when you mess with celestial dragons I have the scars to prove it. Haha anyway we should keep going, don't wanna keep the others at the boat waiting for too long."
After dealing with some bounty hunters the group had arrived at a bar. Y/n looked at the bar. "I've been here before! When I was really little I met a real old guy with a scar! Can't remember what his name though..." "ah! You must of met Rayleigh, he's great isn't he, that's the man we're looking for at the moment."
The crew settled into the bar you sitting next to Brooke and Luffy, the bartender shakky talking about the pirates on the island. You recognized most of them. Shakky walked over to you. "Are you spark by any chance?" "Yup that's my old pirate name." "Huh is that so, it's quite rare for a crew member to have a bounty larger than there captain." She placed a bounty infront of you, it was one of your old bounty posters, you glanced at your bounty. " 4-... 424,000,000 berris!? That's 100 thousand more than my old one!" "Huh? Wow that's a big bounty...." The gears in luffys head slowly turned. "Y/n that's your bounty! H-How is it higher than mine! I'm the captain!" "Don't take it like that Luffy... remember I've been pirating for awhile longer than you, I just had more time that's all." "That does mean that 'spark' currently has the highest bounty of all the supernovas on the island." Shakky spoke with a smile. "This isn't good..." y/n whined.
