10: Judge of Character

The enormous and quite honestly hideous woman sneered down at the three young pirates and the cabin boy. Chara just glared, lazily lifting her knife in a defensive position. Luffy and Frisk were confused, tilting their heads to the left, almost identically.

"COBY! What was that you were saying?! Who are you going to turn into the Marines?!" the woman bellowed, pointing a spiked club at the terrified boy. Chara glared at the woman.

"Oi, you ugly b*tch! I asked you a f*cking question, don't ignore me!" she snapped.

"Chara, don't you know who that is?!" Coby shouted in frightened disbelief. The red-eyed girl just glared, shaking her head.

"I would if she'd f*cking tell me. Who is she?" Coby froze, almost shaking, though he knew not for what.

"That's...that's...that's...THAT'S THE UGLIEST HAG ON THE SEA, CAPTAIN ALVIDA!" He screamed, now closing his eyes as he braced for the inevitable impact of a club. Chara and Luffy broke out into hysterical laughter, while Frisk just smiled, shaking her head.

"Oh my god kid, that was great!" Chara said, lifting her knife to block the angry blow aimed for Coby's head while Luffy punched out some of the henchmen who had also decided to attack.

"Shishishi! Yeah, you really stood up for your dream there!" Luffy chimed in, grinning widely. Frisk gave a smile an a thumbs up to the boy, who was now smiling in awe at the pirates before him.

Chara, meanwhile, glowered at the enormous hag known as Alvida. Parrying the attack with her large kitchen knife, a dangerous look in her eyes, Chara lunged again, aiming for the woman's ample stomach. Alvida saw this and jumped back with surprising speed for a woman of her size, Chara just smiled, dropping and swinging her leg out, tripping the woman. Then, Chara noticed some of the woman's henchmen chasing Frisk.

The red-eyed woman immediately ran for it, when she heard a "thunk" behind her. She looked and saw Luffy, blocking a blow meant for her. Chara grinned, giving a salute.

"Thanks, captain!" she called, going over to aid their sister once more. Luffy grinned, landing a hard blow to Alvida's face, sending her flying over the railing and into the ocean. Chara, now at her sister's side, quickly ran through the crowd of pirates, all over them falling to her attack.

"Demon Blade," Chara muttered to herself, standing upright and looking at the remaining adversaries, most either knocked out or bleeding on the deck of the ship.

"So, why didn't you just sleep powder these guys, Frisk?" Chara said. The younger girl smiled sheepishly saying, "I left my belt in the barrel."

Chara facepalmed, muttering something about why she came with them and how did she forget something like that on an enemy ship. Frisk just chuckled nervously, hoping her sister wouldn't be too mad.

The makeshift group of four now sat in a small boat, making small talk about the island they were currently headed to. Apparently, there was some big-time pirate hunter kept as a prisoner on the island and Luffy, the knucklehead, had become attached to the notion of having the man join their crew.

"Are you insane?" Chara asked once her brother had declared this, "He is a pirate hunter, Lu. We are pirates. By definition, he is our enemy, you idiot!"

"Yeah, but he sounds really strong! Besides, I won't let him join if I think he's a bad guy," he insisted, causing his eldest sister to facepalm.

Goddamnit, why do I have to be the responsible one here?!

"He has a point, Chara," Frisk said with a light smile, "Besides, we'll let you be the judge of his character." The two boys stifled their laughter while the red-eyed girl glared.

"I honestly don't know whether to be proud or to slap you."

"I know; I have a true gift for that. Hey Coby, you never told us how you got on Alvida's ship in the first place."

"Don't change the subject like that!" Coby, now sort of used to Chara's (mostly) empty threats, nodded.

"Well, it all started with a fishing trip…" Several moments later, he had told them of how he had mistakenly gotten on a pirate supply boat instead of a fishing boat.

"Wow, that's so lame!" Luffy exclaimed with his signature laughter and Chara was smirking. Frisk sent her siblings a reprimanding glare, but she almost agreed.

Chara and Frisk found themselves walking through the town while Luffy took Coby to sign up for the Marines as well as to find their possible crewmate, Roronoa Zoro. After much debate and Coby assuring the girl's he wouldn't let the straw hatted boy get into too much trouble, they split up. The girls (mainly Chara) attempted to "borrow" some supplies and they now had a nice stockpile of food, booze, and other useful items. Frisk was lucky enough to come across and abandoned apothecary set with most of the herbs and plants still useable. She could easily make some more of her potions and powders she liked to use in battle.

"You think we should go find our idiot?" Chara asked Frisk as soon as they loaded the last of their illegally acquired things into the small boat. Frisk smiled, nodding as she jumped back on land. They started their walk to the ominously looming base and Chara couldn't help but glare at it.

Although the genocider didn't know too many Marines other than Gramps, she didn't like the idea of a military that would hunt down someone like Ace just for being born. Besides, the Marines, or rather the Celestial Dragons, were the reason she hadn't got the chance to meet Sabo, Ace and Luffy's former brother. Not to mention, from what she heard, the Marines would probably go after her friends and family from the Underground in the event they escaped. She didn't like that idea one bit.

"Chara? We're here," Frisk said, looking at her sister with slight concern. Chara blinked, then realized that they were indeed at the base, looking at a green haired man tied to a crucifix. Bruises and cut littered his tan skin and his breathing was heavy with overexertion.

With ease, the young woman swung herself over the fences blocking them, her younger sister following suit. Chara sauntered over to the man, giving an unimpressed look.

"So you're that pirate hunter Coby was talking 'bout, huh? Don't look that impressive to me. I could've already broken those ropes and took out at least half of this base. You want some help outta here?"

The man looked up with intense dark eye, sporting a glare that could have given the red eyed girl before him a run for her money. Chara smirked while Frisk looked on from a distance, studying the interaction. She wasn't sure if she could trust the man her brother wanted to recruit for their crew.

"F*ck off, lady. I'm strong enough to leave on my own. Trust me, if I wanted to leave, I would've already," he growled, causing Chara's smirk to widened.

"Oh really? Pretty big words there. Hope you'll be able to back them later, it'll be fun to fight against someone other than my brother when we set out for the Grand Line."

"The hell are you talking about?" he grumbled irritably, much to the brunette's amusement. Chara was enjoying this interaction, that much Frisk could tell. Her sister was trying to gauge the man's personality by goading him into a fight.

"What, didn't Lu already get here? Not really that surprised if he didn't. He has a bad sense of direction. He's a weirdly happy guy with a scar under his left eye and a straw hat. Seen him?" Recognition flashed in the man's eyes as he raised an eyebrow.

"Wait, you mean that kid was telling the truth about being a pirate?" Zoro asked, causing Frisk to giggle. The man finally noticed the other girl who was keeping her distance.

"Yep. That guy is out little brother and captain, even though he doesn't seem like much," Frisk replied to the man with a sweet smile. The pirate hunter just scoffed.

"Well, I'll tell you what I told your brother: I refuse to work for some scumbag pirates. Now get lost." Chara shrugged and started to walk back to the wall.

"Oh well. C'mon, Frisk. We need to go make sure Luffy hasn't caused something to spontaneously combust." Frisk gave her sister a confused tilt of her head, but followed her out of the courtyard anyway. Once they were a fair distance away from the base, Chara grinned.

"We're totally getting that guy to join."

A/N: Hey people! We've finally gotten to a main member of the Straw Hats! Whoo-hoo! Next chapter will be a battle and then off they go! If you have any questions, please feel free to leave a review or PM me. I always appreciate reviews, they make me happy. For the reviewer JarOfIdeas, I'm sorry, but I don't know if they'll be seeing Ace or any of the Whitebeard Pirates until they make it into the Grand Line. Although it would be cool to have them meet up, I don't think it would be a good idea at the moment. But, who knows? Maybe I'm lying and we'll see everyone's favorite, shirtless fire user in the near future? Also, I am in desperate need of ideas! I don't really know what I'm doing after this next chapter! Please leave any ideas! Thank everyone who who has supported this story! It means a lot to me.
