"Were going to the celestial tournament! For training and earning money" Gon said excitedly.

Her grin widen, "what about you?" killua asked, looking curiosity at the female.

"I got some business in the same city as the tower. Sooo~ I will join ya"

They all grinned heading for a new adventure.

As soon as the group entered the city, they headed straight for the tower. You wouldn't miss it – for it was the tallest building in the city, by far. As they lined up, Mari lifted her red hood up over her head and to hide her face, earning a weird look from killua.

"What?" she asked smirking.

"You know what" he responded giving her an eye roll at her playing innocent.

The smirked turned into a wide grin, "they don't like me here," she shrugged off-handily, "that's why I won't be joining you in there"

Killua narrowed his eyes slightly, there was something else going on he knew it, instinct told him so. "Don't worry" she commented, "You'll find out soon enough"

The sliver haired boy pouted, but didn't respond as the line in front of them moved.

Soon enough the boys stood in front of the reception, a kind looking women smiled and passed them the forms to file out. Her smile disappeared as soon as she spotted Mari who stood behind them, the women eyes flickered to something they couldn't see before a nervous smile returned to her lips, "please fill out this form with the required information"

The boys nodded proceeding to file out the forms, not noticing the women's sudden nervousness.

Shadows loomed up behind them, Mari looked up at the men from under her hood. "Hey boys~" she purred, gaining the attention of those around them. "Can I help ya?"

"You're not welcome here" one of them responded.

There was three of them, tall and wide in black suits with sun glasses and shortly cut dark hair. All three of them were identical. She pouted, crossing her arms before tilting her head back to get a better look at them, "aww~ I was only giving my friends some good luck, no need to get stressy about it"

"You're not welcome, please leave" the man on the left stated.

This time she turned fully towards the man, "what you gonna do if I don't?" she asked sweetly, a smile dancing across her face.

The men tensed before her as the temperature dropped at the underlining threat, the silence only to be broken by the one on the right as he spoke up, "ma'am, please leave. Let's not cause a seen"

"I jest I jest," she giggled the tense air instantly vanishing, before turning to the pair of boys, "gonna have to go now, don't worry I get in touch" she winked at killua, "see ya soon"

Mari walked out the building of the tower closely followed by the three men, "ma'am?" the one who spoke up last called when she was far enough from the tower. She turned towards them, "try not to get caught next time"

She grinned before turning fully away, a hand waving towards the man. Obviously he knew who she was. Or what she was capable of.

She quickly doubled back into an alleyway, checking the coast was clear she changed her appearance. Brown unruly hair to straight blonde with a black ribbon. Red hoddie to black and white gothic Lolita dress that came up to her knees, white tights and black heeled bucketed shoes. Her bag changed into a black parasol, with she placed on her shoulder opened as to hide her from the sun. Her skin became lighter and eyes greener, face thinner. The only thing that didn't change was the necklace around her neck. But that would never change, no matter what shape she took.

All in all Mari looked like a different person. She stepped out of the alleyway heading back towards the tower, she had to see Gon and killua again before she began working. She giggled to herself, wondering how they would attract to this appearance.

Mari walked back into the lobby of the tower, heading straight to the elevator, where she let her aura do the work, as she searched for the presence of the two boys.

The lift dinged, as it came to the 50th floor, already this far huh? She stepped out to zooming in on the boys.

She walked up behind them, seeing the small smiles on their faces, "now how should I act today?" she mumbled as killua and Gon started talking to another boy. He looked to be their ages if not younger.

"Killua-sama and Gon-sama, I presume?" she spoke softly, even her voice had changed to that of one of the higher class, even a higher pich.

Both boys jumped and turned towards her, "whose asking?" responded killua cold, with a look of distrust on his face.

Good.

"Pardon the intrusion, Mari-sama asked me to deliver something, she did however inform me of how you would reaction. No need to be alarmed, I am just passing this on" she produced a piece of paper and handed it to the sliver haired boy.

"Her message, 'phone me, you better keep in touch killua or I'll take all your chocolate' that is all, have a good day, killua-sama and Gon-sama" she curtsied slightly before turning away.

"Why did she only mentioned you?" Gon moaned.

"A big give away would be that she knows I have a phone and you don't" killua snickered before turning back towards the other boy.

The women grinned as she stepped into the lift, clicking onto the lower floors of the building, where she was going - most didn't know existed unless you where floor 200th and of a certain age.

The lift binged open to the underground bar and nightclub, the blonde stepped out into the room. Due to it being early morning the place wasn't exactly 'open', there was an however occasional fighter, already drinking.

She headed towards the back, no one taking much notice of her as walked though, parasol slung over her shoulder. She smiled spotting the person she had been looking for, she slipped into the seat opposite him. The man scowling at her.

"What do you want?" he growled.

"Mari-sama sends her apologies, she unable to make it to the building today" she spoke softly still smiling at the man.

He signed, putting a hand to his face understand the code, "try not to get caught next time"

"Of course kida-sama!" she nodded, head bobbing. The women character perfectly acted out.

"Mari has got five requests, one information hunt, two heists and lastly two exterminations" he said putting a brown folder onto the table between them.

"Any time limits?" she asked, taking a quick peek at the contents.

"None, put the information need to be collected first, if you wouldn't mind." He took a slip of his drink.

"Thanks, kida-sama see you soon" she stood, putting the brown envelope under her arms before walking out of the tower a smile across her face. she had work to do.

-Later that night-

Mari in her normal form, smiled as her phone ringed. The wind blow at her hair as she shifted slightly, sending the call though her headset. "Hey, killau! Finally decided to call?"

"Oh shush, Mari! What was that thing this morning?!" he demanded down the phone.

She laughed, "oh that? Well few years back, I entered the tower in a competition with the floor masters. Even though in was technically in the rules, I kind of killed them all. Owner of the tower weren't toooo happy about it so they banned me from entering. Normally I can get in without much trouble"

"What really?" she heard Gon gasped on the other end, before killua told him to shush.

"Now boys, what do you want?"

"Where are you right now?" Gon asked

"I'm at work sweetie" she grinned at the naïve boy.

"Doing what?"

"This and that, at the moment I'm just swinging around" she giggled, swinging her legs in the air around her.

"Right," killua unsure with her answer, "you know what Nen is?"

"Nen?"

"Yeah nen"

She paused, moving the camera in her hand about, quickly snapping a spot before answering. "I know abit, why?"

"Just wondering" killua responded, telling her about the encounter with ping and what he had told them about nen.

She nodded, remembering about what Hisoka had told her in trick tower. "Yeah sounds like what I heard too, can't help you much with thought."

She could hear the pout in his voice as killua commented, "Fine then, I leave ya to work"

"Killua wait, let me know if you find out anything more on nen, and kiddo?"

"Yeah?"

"Phone me when you reach the 190th floor, k?"

"Sure, Mari!" she heard Gon yell, she chuckled.

"Good luck guys!" she said before hanging up, concentrating on her job at hand.

She currently was sat, hanging in the shadows of a suspension bridge taking photos of some boat party's below, in a vase network of ropes. Information hunting jobs always paid the best. She had been asked to take photos to identify everyone party member face, she was unsure as to why but she could always guess.

The underground world was a backstabbing reality.
