So far you've been sailing along quite smoothly ever since you left the Baratie. Luffy is resting at the bowsprit of Sanji's small boat, and Ghin's taking his first real rest since he became a pirate along with Yosaku and Sanji. You were taking a nap from all that chaos that happened.
Luffy lets out a yawn as he awakens from his nap. "This weather's perfect!!" He then rushes to the stern of the boat. "So which way is the Grand Line??"
You opened one-eyed and noticed that Ghin tensed up at the mention of that dangerous sea.
You chuckled and said, "Easy now, Luffy. I know you're excited but we have other business to tend to, such as bringing your dear navigator back"
"Listen to (First Name)-koi!! She knows what she's talking about" Sanji defended you. "You need to sit. Jeez, you bug me"
"How do you keep up with this guy, (First Name)??" Ghin questioned.
You hummed in response. "I don't know. He just listens to me. Either give him what he wants or knock him out"
Luffy apologized but his excitement was still present. "I'm just excited that we finally got a cook on board!! Now we just need Nami, then nothing will stand between us and the Grand Line!!"
"Nami??" Ghin repeated confusedly.
"She's their navigator. The one I told you about earlier after we set sail" you explained.
"The one who stole their ship earlier?? Remind me again why would you want someone like that back on our crew??"
"She's a great navigator. Great at what she does. Plus there must be a reason why she did that" You defended her.
"Nami" Sanji sighed dreamily and the smoke from his cigarette was now heart-shaped. "I can just sit around all day and think about how beautiful she and (First Name)-koi are. I can't wait until I get to see her again"
Luffy sits down on the bow rails of the boat. "So, are we getting close to where Nami is?? Y'know, the island??" he asked Yosaku who hadn't said a word since they left.
Then he had enough and explained to him about Nami's reaction when she came across Arlong's wanted poster before she went and stole their ship called the Going Merry.
Luffy brushes Yosaku's worries with a yawn. "That's nice. Let's eat"
"Sounds good" Sanji quickly agreed.
"I could go for something as well" Ghin joins in.
"Same here" You spoke.
"Don't tell me you guys are so clueless that you have never heard of the evil Arlong!!" Yosaku exclaimed.
"I'm kinda offended that you assume that," you said with a blank expression but it fell on deaf ears.
"Uh, no. So, who is he??" Sanji asked.
Luffy is just as equally as confused as Sanji is. "Yeah"
Yosaku's head dropped in defeat. He then blew a whistle loudly to gain everyone's attention. "Listen up!! All of you!! Time for your education on the cunning shark that is Arlong. Arlong is a Fishman who used to destroy everything in his path up and down the Grand Line," the bounty hunter explained.
"A Fishman??" Sanji echoed.
"That's cool" Luffy commented. "I don't think I've ever met one of those before"
"I've heard that females on Fishman Island are some of the most beautiful creatures in the world to behold" Sanji swooned then he recalled your hybrid and mermaid forms. "Dear pearl, you must be a gift from that very island"
"I don't know about that, Sanji" you humbled yourself.
"Oh, yeah!! (First Name), where did you get that tail from?? I want to see it again" Luffy beamed.
"I got it after I turned 18 years old. It just happened overnight. And about showing you my forms, I could show them to you in the water cuz there isn't any space in the ship" you replied. You stood up and jumped off the ship into the ocean. Luffy, Sanji, and Ghin looked over where you jumped as you surfaced and swam in your mermaid form.
Luffy's eyes sparkled in excitement, Sanji swooned over your form while Ghin was awestruck.
"That's so cool!! I didn't know you could do that!!" Luffy jumped up and down on the boat.
"Amazing . . ."
You jumped back onto the ship and shifted to your hybrid form, revealing your shark tail while your legs were there. You lay down on your stomach to give them a clearer view.
"Can I touch them??" Luffy asked as he couldn't hold himself back from excitement and curiosity.
You chuckled. "Sure, you can. Just don't touch my sensitive- Aah!!" you jolted from the sudden touch on the sensitive part of your tail.
"Woah!! It feels so smooth!! I wonder if you can carry me with your tail" Luffy rubbed your tail.
The thing is, you have a very sensitive spot on your tail. No questions asked on your reactions.
"L-Luffy, I was about to tell you to not touch the sensitive spot on my tail" You turned to him as you frowned.
"Hm?? What happens when I touch it??" Luffy asked.
You turned back and sighed. "I doubt you wanna know. Plus you're too young to understand this"
"Hey!! I'm not a little kid anymore!! I'm a man!!" Luffy retorted.
"I don't think you should question her anymore. She might not want to talk about it" Ghin defended you.
Luffy pouted when you shifted back to your human form. "I still have the characteristics of a shark. My teeth and my gills. I always wear a crop top because my gills are like my second pair of lungs" You showed them your shark gills and your sharp teeth. You accidentally showed them your tongue which is quite long.
"Ah, sorry about my tongue" you apologized. You slipped your tongue back into your mouth and wiped off your saliva, not noticing the flushed faces of the others.
Luffy was the first to snap out of his blush and change the subject. "Fishman sounds weird" He took out a sketchbook and showed you a drawing of what he thought it looked like. "Do they look like this??"
Sanji and Ghin laughed at the terrible drawing.
"CAN'T YOU ALL JUST FOCUS FOR JUST ONE MINUTE, PLEASE?!" Yosaku shouted. He then calmed down and explained. "Alright, I will start from the very beginning. The reason they call the Grand Line a pirate graveyard in the first place is because of Arlong and the other two powers like him who rule over it"
"You're talking about the Seven Warlords of the Sea, right??" You interrupted.
"Yeah, that's right!! It makes me feel better that at least one of you has enough sense about the Grand Line"
"Seven Warlords??" Luffy repeated.
"The Seven Warlords are pirates authorized by the government" Yosaku continued.
"Seriously?? Why would any pirate on the sea want the government's approval??" Sanji inquired.
"For protection. The government looks the other way in exchange for a cut on their treasure and they're allowed to exist. Of course, to other pirates, they're just government dogs. But they didn't get to where they are by being weak. These guys are powerful. And not to mention the Unofficial Eighth Warlord"
"Unofficial Eighth Warlord??" Ghin questioned the last part.
"The Phantom Theif, Arsene. There are rumors that she was offered the Shichibukai position despite the full vacancies because the World Government sees her as a bigger threat due to unknown reasons. It's to keep them in check"
You chuckled while Sanji and Luffy were holding back their laughter as they glanced at each other. Ghin raised a brow and looked at you, gesturing you whether to reveal this information. You nodded as you smirked.
Ghin turned back. "The unofficial eighth warlord you're talking about is right in front of you, Yosaku"
"Eh??"
"Hey. Over here" you waved at Yosaku.
"EEEEEEEEEEEEEEEHHHHHHHHHHHHHHHH?!?!"
Luffy and Sanji couldn't hold back anymore and started laughing.
"Wait wait wait!! Hold up!! You're Arsene?!" Yosaku asked while pointing at you.
"Why would I lie??" you said with a neutral expression.
"I-if that was the case, then there's no need to worry about losing against Arlong!! We have a powerhouse right here!!"
You hummed in response. "Yeah, that does seem to be the case"
"Wait. Then where is your ship?? There's no way you swam in your shark form to the East Blue from the Grand Line" Yosaku looked around the ocean.
You grew an irk mark on your head when you thought about your destroyed ship. "I was on my way to the Baratie when my ship was destroyed by a cannonball"
"Destroyed by a cannonball?? How could they not notice you??" Ghin questioned.
"I was resting on a small rocky island with a big rock behind it when suddenly rocks fell from above and sank my ship along with all my supplies. All my money is in there which is why I asked Zeff if I could work there again" you explained.
"No wonder. Who could do such a thing to you??" Sanji frowned, thinking of kicking their asses for destroying your ship.
Luffy and Yosaku went pale from your explanation.
"Y-you didn't see the ship, didn't you?" Yosaku asked nervously.
"Hm?? I saw what it looked like. It had a weird goat figurehead on the front. When I meet these bastards again, I will make them dummies for my training" You cracked your knuckles.
Luffy shrieked in horror and went pale from your words. Yosaku was sweating in fear of your wrath. Ghin noticed it and raised a suspicious look at them.
"What's wrong?? Why do you guys look so pale??" Ghin questioned. You looked at them and furrowed your eyebrows.
"N-nothing. I-it's just that I get reminded when you did that when we were younger" Luffy nervously tried to cover it up. You're only making it even more suspicious with your stuttering, Luffy. . .
Sanji stood up. "Anyways, I'll go get lunch started"
"Bout time!! Let's eat!!" Luffy cheered while changing the subject.
"What?? Food??" Yosaku looked up, away from suspicion.
"What are you in the mood for??" Sanji rolled up his sleeves.
"I want meat right off the bone!!" Luffy shouted with gusto.
Yosaku ran up to Luffy. "I want sauteed bean sprouts!!"
"I'll stick with the fish," Ghin said.
"I'll have fish as well" you voiced.
"Okay," Sanji walked to the ship's kitchen. "Leave it to me" He grabbed a pan and ladle before getting to work. "This won't take long. Meat, bean sprouts, and fish. No problem"
"Man, having a cook is the best, huh??"
"It sure is" Yosaku agreed.
"Bring me meat!! Lots of meat!!" Luffy demanded.
"Sprouts!! I want bean sprouts!! Bean sprouts!!" Yosaku shouted like a mantra.
You then realize the mention of having Sanji as their cook. "Speaking of which, have you thought about what position Ghin holds on the Strawhat Crew?? Mind telling me what positions your other members held??"
"Hmm. Let's see, I'm the captain, Zoro is the first mate/swordsman, Nami is the Navigator, Usopp is our Sniper and now Sanji is the cook"
"As the chief commander of the Kreig Pirates, I took care of keeping many of the newer recruits in line as well as take note of all the loot we pillaged" Ghin explained his previous line of work.
"And though you may not show it, you're probably the most well-educated out of the whole fleet"
You run through the possible positions that are suitable and you get one. "How about the quartermaster of the crew??"
"Quartermaster??" Luffy tilted his head in position.
"It's a bit similar to his previous job. They help maintain order on a ship, settling quarrels, as well as taking into account the amount of treasure that might be brought on board" you explained.
"Alright then!! We have a quartermaster!!" Luffy cheered.
Ghin also looked satisfied with his new position.
Once the table was set, it was a bit of chaos. Sanji waved off Luffy and Yosaku's thanks for the meal saying that he's practicing for the evening he can make dinner for you and Nami. Ghin shakes his head at the lover boy chef's ways regarding women, finding it hard to believe the tough guy he fought could become so soft when it came to the opposite sex.
You chuckled and asked, "Now you know why I had to leave early before I got caught??"
"It's surprising to see this side of him"
"You'll get used to it"

"There it is!! Arlong Park is dead ahead!!" Yosaku announced.
"Right!! Next stop, Arlong Park!!"
