Chapter Ten:

"He's still alive and hasn't surrendered, meaning that the match is still ongoing."

It should be simple, he was unconscious, they needed him to surrender or die, Kurapika needed to go and finish him off. Somehow though, Kai didn't think it was going to end up going like that.

"Oi Kurapika, go finish off that worthless trash."

"I refuse." Kura-chan promptly replied.

Upon being asked why he gave an almost self-righteous response;

"The fight is over; he clearly lost his win to fight even before I had punched him. I will not fight someone who has lost."

Leo-san was practically spitting angry at this. After all, it was his match next that was being held off because Kurapika was choosing the moral highroad.

"Hey," Killua stepped forward to speak to Kura-chan, "If you don't want to get your hands dirty, I'll do it. You've never killed someone, that's the problem right? Are you scared?"

"I've never considered if murder was scary or frightening. This is a one-on-one battle either way, you aren't allowed to interfere."

Kai floated next to Kura-chan, her legs floating in a pretzel style of sitting, "If it's because it's a one-on-one battle I have a way of doing it from right here. No one will be able to tell. There shouldn't be a problem right?"

Killua looked at Kai, wondering about that. There seemed to be no reservations in her for killing that man, with the look in her eye it definitely seemed as though she'd done it more than once before, but what he was really curious about was how she would do it without them knowing it was her.

It seemed that he wouldn't be able to get his answer though, when Kurapika replied to her, "I refuse. I refuse to have him killed as he lost his will to fight."

Kai actually got a little bit angry at that, "We're a team you know, don't you understand that you are ruining our chances as well."

Killua agreed with that, having been about to say it himself before Kai cut in with her offer.

"Even so, I won't change my mind."

This was why Kai sometimes had difficulty hanging around with moral highroad people. Even though the Seven Deadly Sins Captain was like that sometimes, he never did so at the expense of the team. This was just pathetic.

Leorio called for a show of hands on who wanted Kurapika to finish off his opponent so that they could get the show on the road, only no one voted to have him killed.

Kura-chan wouldn't change his selfish mind. There was nothing for stubborn fools.

Kai knew though, that this wasn't something that she would forget. Before, Kurapika had been sliding his way into her friend category. Now she knew, that Kurapika didn't really care if the groups suffered through his choices like this, she just couldn't trust him. Allies was what they were as of now.

You can't really be friends with someone you can't trust.

So they waited, for hours. With each one that passed Kai felt more and more sickened by Kurapika's behavior. He wouldn't even use that common sense Kai thought he had to at least check on the body, try to get him to awaken.

Gon and Killua were the first to notice something was wrong, "Hey, it's quite possible that he's already dead."

"Ehh?!" Leo-san explained, getting up from his place laying down, just looking at his stopwatch.

"Well, he hasn't moved in hours." Gon expanded on the idea.

Killua looked at Kai out of the corner of his eye, practically yelling the question. After all, the former queen had said that she could kill the guy without anyone knowing differently, Kai gave an honest answer though. Simply shaking her head, as she hadn't done it – Even though she kind of wished she had so that they could have had this over and done with hours ago.

"We want to check the body!" Leo-san exclaimed to the other side.

However it seemed to be what the person wanted, judging by the small smirk that Kai could see even from all the way on the opposite side of the rather large room.

"Then let's make a bet. We will bet with time."

With that, the third match unofficially started.

Leorio went and checked the movement of his pupils. They decided to bet using hours. Leorio betted that he's not unconscious while the opponent betted that he was. Leorio took blue man to the edge of the platform and was about to drop him down before blue man opened his eyes and ran back to the rest of his team in disgrace.

With that, the third match officially started.

The next bet was fairly simple, and rather obvious.

"Let's bet a few hours on whether I'm a woman or a man," The CLEARLY women suggested.

"Even if you claim to be a woman, there's no way to be sure," Leorio pointed out, and Kai already knew how this was going to go down.

"Well you can search me until you're satisfied."

"He's going to bet that she's a male," Kurapika claimed.

"Yep!" Killua agreed.

Gon just looked confused, wondering why on earth Leo-san would do that. Did he think it as a trick, and that the girl was actually a guy?

Leorio 'thought' about it, "I'll bet 10 hours on male."

"Perverted old man…" Killua said, unhappy with the outcome.

It was slightly hypocritical, for her to new disgust at Kurapika not to spread to Leo-san considering it was a similar situation. Leo-san was putting his ideals above the team, but it was also slightly different. At least he wasn't doing it out of some misconstrued moral highroad.

"Unfortunately I'm actually a woman," she had a smug smile on her face, not at all caring about what was going to happen next.

"Oh, damn it!"

'You look way too happy about it.' Thought Kurapika, Killua, and Kai

"Huh? You're a girl? I'll have to check just to be sure!"

"You want to see for yourself?"

Kurapika covered Gon's eyes just in time.

Kai moved her hands to cover Killua's eyes, "Don't worry Kil-kun, I'll protect you from the scene that dirty old man is making."

"Oi! I was going to shut my eyes, besides don't call me Kil!" Killua exclaimed, trying to remove himself from the females hold.

After that, they had a match of rock paper scissors. They betted on who would win. Eventually, Leorio's opponent won this round, Leo-san returned in disgrace, the first lost his fault.

Either way, they now had two wins and only one loss, it was pretty good odds that they would be able to win this thing at this point, even with Leo-san having lost.

"Hmm… Well I guess I'm next." Killua said, hands in pockets as he walked forward to face whoever would be unfortunate enough to have to face him.

"EHH?! I didn't even think about it. All that is left are these kids, of course they will lose. Shit, I really needed to win my round!" Leo-san exclaimed.

"…Oi what's that meant to mean. Damn this guy is starting to really piss me off!" Killua said with a narrowed look. Kai could feel her eye twitching in annoyance at the 'teen'

"Seriously, don't give up before we even know what the contest is. Well, if it's something like mental math I'm surrendering."

Leo-san went on to talk about how they still had a chance, Kai was paying more mind to the other side of the room. Of course Ban wasn't, but the other criminals seemed to be scared of whoever was coming next. Somehow the former queen seriously doubted they had any chance against Killua either way.

The guy uncloaked himself showing a weird looking blond old man. He seemed like the type of person all young kids should run away from.

"That guy…" Leo-san said, slightly worried even for Killua who he didn't really like all that much, "We should take the loss…"

Leo-san went on to explain who the guy was, what he'd done. It was certainly disgusting, but it was different from the abilities Killua would have. He'd probably killed people like this Johness before without any problems.

Killua pretty much ignored the warnings that were sent his way from Leo-san and stepped forward to his opponent.

"Kil-kun, I'll give you a kiss on the cheek if you win!" Kai teased him

Killua could feel his face light up in a blush, "Don't make me so tempted to lose! Also, don't call me Kil! – You're going to keep doing it aren't you…" The last part muttered under his breath as he reached the platform.

Nearly the second the match began, it was over.

Killua was holding the man's heart in his hand, covered with some cloth, but still beating. The technique used there was actually pretty impressive; it wasn't easy to rip a heart out like that, especially with so little blood.

"G-Give it back…" The man slumped over, his hand outstretched to receive his heart. Killua was nice enough to fulfill his final request, placing the heart in his hand before walking back up to the team.

Turning to the enemies, "Now… That's three wins and one loses. Kai still has to fight right?"

"Damn right she does!" Came a slurred voice, and the sound of handcuffs coming off as her opponent came into light.

Kai started stepping forward with a smirk the second that she saw him, having waited long enough.

"Kil-kun should get off the arena it's my turn now." As she said that, Ban kicked the corpse off the stage and stood, pulling off the cloak.

He was wearing just a pair of pants, his muscles shown completely, he had a slight beard, and blue but edging on silver hair. His tattoo on his side was in clear view, a fox.

"Been awhile, aye Ban?" As Kai stepped the final step to be facing the complete opposite as Ban. Killua had just stepped back into the viewing platform, but was giving the match his complete attention.

The whole group was, especially when it became apparent that the two knew each other.

"Mhmm~ I see you've actually changed which is quite the surprise, considering." Ban practically sang out the words, as he usually did when he wasn't serious about something, or was excessively teasing.

Kai gained a pinched expression, "Mmm… I was annexed, as punishment they ripped that from me. Must you bring up bad topics at our first reunion in what, eight years?"

"I can't help but want to get Kai worked up considering I haven't had a good fight in forever."

"That's because you let the holy knight's capture and imprison you. Embarrassing, for one of the Seven Deadly Sins." Kai said in a matter of fact tone.

"This coming from the member that fled the country."

They bickered back and forth, as was their way of greeting each other. Had it been Ban and the Captain which had been reunited it would have been different, most likely with a lot more bringing the house down. The back and forth insults were definitely more Kai and Ban's thing.

The group was pretty confused as to how Kai knew the criminal so well, but Kurapika gave a sharp intake of breath at the words 'Seven Deadly Sins' and refused to explain. That probably didn't mean anything good.

Eventually the two had calmed down their little greeting

"Ban, you know this arena is the perfect size." Kai suddenly mentioned, smiling sharply toward her opponent. Chastiefol's pillow form floating behind her, ready to change configuration at the slightest mental command.

"So it's the Captain's rules then?"

Both of them stepped forward into the middle of the arena, stomping a foot down in a ready position. They stayed in that position for a moment, looking at each other, tensing up in preparation for the fight.

"Please externally explain 'Captain's rules' so we can judge accordingly" The loud speaker interrupted, just as tension was building to its max.

Ban looked seriously put out at the interruption, so Kai opted to explain, "The Captain's rules for Inner- Seven Sin's fights, rules are as follows; One, no permanently killing. Two, First person completely out of arena loses. Three, no bringing the arena's surroundings down around you. Four, no permanent damage to sanity. Five, the first person unable to fight for 15 seconds loses. Six, surrender is allowed. That's the rules." Kai ticked them off on her fingers as she went down them

There were actually several unwritten rules, ones that you needed to read between the lines for.

Killua, Kurapika, and Leo-san wondered about that. What kind of sparing match are you taking part of if you need rules against 'permanently' killing someone, or causing permanent mental damage?

They were about to find out.

Kai pulled out a coin and threw in the air, both Sins tensing, waiting to hear the drop.

When it hit, there was an explosion of movement. Ban knew Kai's weaknesses to a T. After all they had worked together for many years, so it was no surprise that the moment the coin hit the ground, Ban attempted to grapple her into close combat.

Kai knew that was coming, it was something that Ban always attempted but always failed at. Until now that was, as Ban had grabbed her by the pig tail with a dirty smile on his face. The former bandit didn't care how low a move he had to make to get the win.

Ban punched her in the stomach, repeatedly. Each time he asked her if she wanted to give up, but instead got something else gasped out, "Chastiefol Configuration One: Spear."

Her opponent heard her, but paid it no mind in favour of dishing out more damage before she found her way loose. This was his mistake –

Whoosh

Splat

Crimson

Blood dripped from Kai's face, getting all over her clothing, the grip on her hair loosened to slack. The former queen took this chance to jump back a reasonable distance. The sight before her was just as planned.

Ban's heart was impaled straight though. The man slumped to the floor, a quick move later, and Chastiefol was jerked from the 'corpse' of undead Ban.

The watchers were suitably confused.

Rules stated that killing wasn't allowed, yet there was a dead body on the floor.

Killua was surprisingly one of the most effected throughout the experience. Every punch to the girl's stomach made him wince and fight the urge to look away. At the same time, the way she took all the hits, no sound except the fail inaudible gasp, made him warm. Kai was strong, able to endure pain like that. It made him feel, admiration?

Gon was simply cheering on the fight, although suitably worried about the harm toward his friend as she was punched in the stomach, she had nothing but faith. This paid off it seemed, considering she clearly beat her opponent.

Leorio was fighting consistently not to look away, especially when Ban had been hitting their teammate. The oldest looking man had been spitting expletives toward the small girl's opponent, this attitude quickly changed when the man lay ruthlessly slain. Leo-san didn't really know what to think.

Kurapika could barely keep his mind on the fight. The implications of Kai being a member of the Seven Deadly Sins lay heavy in his mind. When looking up the Phantom Troupe, there was a mention of a group similar from an un-united continent, the biggest criminals they had. The Nanatsu no Taizai, or Seven Deadly Sins. Not much information was available from that place, but the crimes committed were said to be unforgivable. It sickened Kurapika, to even think he had been close to befriending a criminal such as that. Kai had just killed her comrade without any remorse, just reinforcing the idea.

The watchers seemed to think the fight was over, it wasn't.

Kai didn't stand down, staying tense and waiting, looking at Ban's corpse for signs of movement.

"Oi, was that needed?" The same deep gravelly toned voice everyone recognized as belonging to Ban spoke, and the corpse sat up.

"Ban was hurting me, besides something like that won't kill Ban, nothing can." Kai rolled her eyes, Chastiefol spinning in idle circles as Kai slowly floated to a height over Ban's head.

It almost seemed like Kai had the upper-hand.

So why did Kai have a really bad feeling.

End Chapter:

Authour Note: Soo... A lot happened here. Ban in a fight, one of my favourite from Taizai who fights in with this just too damn well considering his situation at the time in that show. I have every intention to add in a Taizai arc although I'm not sure if before or after Ant arc. After all, we got to wait quite some time before the more content comes out in Hunter X Hunter huh? ... Wow I just notice how long that will make this story. Oh well, it's worth it. It's all caught in my head right now anyway.

Read and Review! I would like to respond to your reviews but I haven't gotten many. It's sad :(!
