Tall and impressive, the Heaven's Arena loomed high above the city. The great tower rose like a single sunflower, its many levels jutting out on either side like leaves. Each one leading up the massive stem to the untouchable face; the coliseum. Capping the monolith sat the arena wherein the most prolific fighters did battle. When she first set eyes on the structure, the young Spirit Detective felt unbridled excitement. Since she first heard of Heaven's Arena, participating consumed her every thought. She desired a place to demonstrate her abilities. Coming from the strict tutelage of Genkai, the young woman wanted to test her strength against worthy opponents freely and without restriction.

In the past Genkai had helped her to wield her Spirit Energy with almost surgical precision. In a single year, the young woman had undergone fierce training in mind, body and soul. She learned alongside Yusuke, Kuwabara, Kurama and Hiei how to harness and use her power for the world's good. There were times when she longed for her home in America but those pining's were few and far between as Genkai kept her involved in one rigorous test or another. Through the old psychic, she gained formidable knowledge in battle tactics and strategy. In addition, her physical body was molded into that of a warrior's. Her arms and legs were strong and toned, her stomach was flat and hard. Her breast size shrunk a bit but not enough to take away their alluring shape. Her agility and endurance increased to where Hiei often challenged her to one-on-one fights. Thus far, Hiei had yet to lose and she would be damned if he LET her win. She had one victory on Kurama and many on Kuwabara. Yusuke, on the other hand, was a different matter. In power she was most like him and as such their fights ended in draws. He found it positively great her progression and engaged her in battle to assist her development.

They spent so much time together that Genkai began to suspect other reasons for the solitary matches. The young woman and Yusuke both refuted the rumor and insisted that their relationship was platonic. Genkai frowned on romances during training believing it to be too large a distraction. Though what she did not know was that her newest pupil and Yusuke had, in fact, attempted a try; A single kiss. Both joined in willingly and found it hard to stop yet when they realized what they had done, they agreed that it was not the proper time. They maintained their friendship and placed their growing attraction for each other into their fights. Blasts of blue and white Spirit Energy lit Genkai's temple complex. Scorched earth and broken trees were left after their battles, decimated by Yusuke's Shotgun and her White Arrow Assault. Genkai monitored the young woman's strength and was pleased to see her rise to Yusuke's present level easily. Only when Yusuke would receive the Spirit Wave would their power level shift. But she could still reach even that high, Genkai often thought.

The young woman continued with her training, evolving her Spirit Energy. However, she soon grew tired of merely fighting Yusuke and his friends and begged to be enlisted in the next Dark Tournament.

"Let me join Genkai," She said with contention. "I can do it. I'm strong enough."

"No. Not yet. You are not ready yet."

Reduced to sit on the side and watch changed her and she made the decision to go off on her own. One day she packed her things and went to leave Genkai's temple when the old woman stopped her. The young woman explained to her that true advancement came with practice and experience.

"You cannot fight regular humans (y/n)—that would be murder." Genkai told her.

"I know that. I will find others who have abilities. I will take them on and defeat them all. When I return, I will be different. I know enough how to keep my Spirit Energy under control. I will become powerful on my own."

Those had been her last words to the old psychic. Now a year and a half later she found what she searched for. I'm ready, she thought. Plus I have a few new tricks up my sleeve that I can't wait to try. As she walked through the city she overheard three children discussing a very interesting topic. They spoke of some force called Nen that, if harnessed, was used to win in Heaven's Arena. The young woman followed them at a safe distance and completely withdrew her energy. She did not want them sensing her. Using one of her new skills she heightened her hearing and listened in on their conversation. Nen was powerful, she gathered, much like Spirit Energy. Yet unlike Spirit Energy, which could be transformed into Sacred Energy with the right training, Nen was a mortal (life) force and had limits. Based on their details of one notorious Nen user named Hisoka, the young woman surmised that his strength was equal to an upper B class demon, like the younger Tugoro. Hisoka…he might be the one I should contend with.

She rolled the name on her tongue and enjoyed the way it felt. Hisoka. The syllables rose and fell nicely. I wonder if he will be hard to find…

The following few hours went by in a flash. She entered into Heaven's Arena and won her first match with a sound high kick. Her opponent was sent flying from the square ring. The kick was ruled as a critical hit and knockout and she won entry to the famed 200th floor. As she made her way to the elevators, she picked up on feint tendrils of energy resonating from her destination. Nonetheless she took the elevator and rode it to the upper level. The instant she stepped from the lift, the menacing energy nearly choked her. She trailed its source rounding a corner to a singular hall. She stopped short. It encompassed an area of the passage that, coincidentally, led to the registration booth. Curious, the young woman approached the whirling mass of dark energy. It formed a de facto wall, made to intimidate her.

What is this stuff? She reached out to touch it. Pulling her hand back she studied the substance. It was thick and viscous on her fingers. This is not demon or Spirit energy… bringing it to her nose she sniffed it. It has no scent. Usually energy has a smell of some kind. The more she rolled it between her fingers, the more it took on the consistence of …gum? The young woman widened her eyes. Stretched tightly between her index and thumb was a strand of pink energy. Ok, now I'm interested.

"Wow, it's like bubble gum. Is this Nen?" She said.

Checking quickly to see if anyone was coming her way, she grinned and stuck her whole left hand into the mass. She retracted her arm and laughed upon seeing the energy stuck to her like glue.

"If this is Nen this is going to be awesome!" taking a few steps back she whipped the elastic energy like a whip. "Aw I gotta find out. Hey, I know you're back there. I can sense you. Tell me, is this your Nen ability?"

From beyond the dark wall of aura, its owner watched the strange woman interact with his Nen. She was unafraid of it. Actually, she was playing with it. He had never seen this reaction before. Who is this girl? He thought. She has no fear. It's like she knows she could destroy it. I must get a better look.

"Why do you not come closer?" Came his hauntingly sweet voice.

She started, not expecting the tone to be masculine. "Who are you?"

"I will not answer that until you prove yourself worthy of hearing my name."

The young woman smirked. Inside the wad of pink Nen she closed her hand. Sending a bit of Spirit Energy into her fist, the sticky substance melted away. Aware that she was in the presence of the creator of this obstacle, she put aside the childish antics. Setting her eyes hard she released her energy. It surrounded her, forming another of her new abilities; the Spirit Shield.

"Prove myself? If you wish." She took one step, then another.

The master of the Nen wall blinked in wonder. She was walking through his Nen. No pain rattled her face, no anguish struck her limbs. His barrier fell away from her as if being nullified. His eye twitched. It seemed as if she was also weakening his Nen somehow. How can she do this?

"Your power has no effect on me, whoever you are. As you can tell I am unfazed." She came to the end of the Nen wall, stepping through the void.

Her white, glowing Spirit Shield was invisible to him and he narrowed his piercing yellow eyes in frustration. Why don't I see her aura? If she can manipulate her energy that proficiently so as not to be detected at all, she must be formidable indeed.

She emerged unscathed and dissolved her shield. Unfortunately for the Nen owner, she was not foolish enough to let her guard down. Her powers braced, she flitted her sight down. What she saw surprised her. Seated on the floor was a man in what appeared to be jester influenced clothing.

The man looked up at her with half lidded eyes. She could not help the flash of red that colored her cheeks, despite her efforts to keep it at bay. His gaze was just as gripping as his Nen and without breaking their stare, he rose to stand. Like a grasshopper his long legs extended, his strapping arms flexed as he brought his hands to rest on his hips. Her breath halted. Those hands! They were perfect; their form, the length of the fingers, the subtle hint of vein under the white flesh as they contoured over his knuckles. Their connection to his wrists and forearms resembled those of a marble statue—flawless. His arms were strong and enticing and the heat in her face increased as she noted how the ivory skin moved over the cords of muscle like milk. Her chest rose with a deep intake of breath. His chest was broad leading to his square shoulders. She observed the smooth column that was his neck and lowered her lids in approval.

"I do not need to guess who you are. You're Hisoka aren't you?" She asked in a low tone.

Hisoka smiled. His lips lifted smartly giving him the appearance of a cunning fox. "You guess correctly. I am Hisoka. Now it is only fitting to know who you are."

She felt herself smile in return. She mused at the painted star and tear drop on his high cheeks. Even his face was immaculate. His nose was long and thin, coming to a slight point. His forehead was smooth like porcelain. Arched brows sat testily above eyes of striking yellow contrasting with his shock of spiked red hair.

"Why should I tell you anything Hisoka? You tried to hinder me from registering. And seeing as how I easily resisted your Nen trick, it looks like I win. And we haven't even fought properly yet. So as far as I know, you are not deserving of my name."

Hisoka grinned devilishly now. His face shadowed by his mounting blood-lust. This woman bested my Nen and now she insults me. I shall have to remedy that. A task I will enjoy!

"Then how will I earn my knowing your identity then?"

The young woman tilted her head. "What about a battle?"

Hisoka's smile widened. The familiar tingling in his fingertips traveled up his arms and down his legs. His drive was increasing rapidly and he knew he had to quench it before he ripped into her. Struggling to get his maddening lust for blood under control, Hisoka also pushed down the growing bodily lust for her. To Hisoka, body and blood lust were remarkably close and he could hardly feel one without the other nearby. This woman wet his appetite for power, as the boy Gon did. But by the same token, she was extremely beautiful with her long dark hair and foreign features. Her eyes, he was titillated to see, were the exact same color as his. She fueled his need for sex just as profoundly as she had his wanting to take her in the arena. He loved a challenge and the thoughts of what this strange woman could provide made his throat tighten.

"Yes. A battle. The two of us together in the ring—it seems almost poetic no?" Hisoka licked his lips hungerly. "I am very interested. Could you be a Specialist?"

She raised a brow. "A Specialist? What's that?"

Hmmm, I'll take that as a no. "Then, can I get a hint?"

He's trying to get me to reveal what my Spirit Energy is so that he can train to best it. Good luck. "It's energy."

Hisoka's heart rate sped up. She's figured out what I'm after. Oh! This is torturous. I must discover what her power is. My whole body is burning. I can practically taste her. He touched his lips and chuckled quietly.

"I see. So you are going to make me guess are you? Fine. I will think carefully on it. In the meantime, I propose we should observe each other's skills."

He is really determined to figure me out isn't he? She thought. Although, he does have a valid point. If I can watch him fight I will have a better idea of what will be expected of me here. And no matter if he sees me because he cannot see my Spirit Energy. And apart from his Nen his spirit is not heightened to use Spirit Energy…so in this respect he is a normal human. Moreover if I can get him to deplete his Nen then he will be powerless.

"I agree. We should take note on each other's power." She stated with a shrug.

"Excellent. I fight in two days. I will see you in the stands." Hisoka winked.

Extending his right hand, Hisoka reached for a strand of her hair. She tensed and watched his digits caress her locks. Hisoka smirked darkly at the red hue painting her face and focused his Nen into his hand. I want to see if she will be able to sense my Bungee…

Before he could finish his thought, her hand clamped down hard on his wrist. Under her grip, Hisoka watched as his aura was overpowered by an invisible force. She glared up at him with cold, knowing eyes.

"Don't. I'm not some newbie that you can trick with your little charades. As a matter of fact I find your attempt insulting. When we fight, I hope you will treat me with respect and battle me like the blood thirsty beast that you are."

Hisoka was raving. His chest constricted in unstinted thrill that he thought he might turn inside-out. Tremors lightly shook his extended arm raising goose pimples along his light skin. They traveled down his spine and over his hips. A cool sheen of perspiration dampened his clothes. His teeth grated hard together. I don't know how much longer I can stand it.

The young woman had only met him but already she knew there was something amiss about his mental state. It was clear that he desperately wanted to tear her apart. It poured out of him. And he was having a painful time trying to restrain his yearnings. In a perverted way, She was flattered that this man saw her as an opponent worthy of such a reaction and she too felt similarly towards him. Finally here was a person who could more than likely withstand her powers and give her a descent spar. He would not disappoint her by going half-cocked in their battle.

"Oh, believe me my dear," Hisoka purred dangerously. "When we face each other, I shall make you writhe as I discover what it is your hiding and take you down."

She flashed her teeth in a dark smile. She removed Hisoka's hand from her hair and released it by his side. Taking two steps forward, she stood at his chest, her head up to look at him. She liked this Hisoka. Her attraction to his beauty was apparent but her inclination for his Nen abilities was stronger. She had to give him credit for his seductive allusions, making her writhe and the like, and figured that if he was going to play that card then she might as well. Let's even this playing field, she thought. Hisoka watched her right arm lift slowly, and tensed as he felt the back of her hand brush against the loose cloth of his trousers. Grazing over his hip, she worked her hand gently up his firm belly, up his chest and along his neck. Hisoka could hardly comprehend what was happening. His yellow eyes clouded with volcanic lust and they lulled beneath his shutting lids. They snapped open when her hand closed around his throat, pushing his head back into the wall. She held him not in malice but in trial. She was displaying her fortitude as one not to be underestimated.

"You seem pretty sure of yourself, Hisoka. But I have come a long way and I do not intend to loose. I hide nothing but my name. If you are unable to detect the power I employ then that is a shame for you. Being afraid of something you cannot see will be rather humiliating in the arena. I'll tell you what though, when our day arrives, I will tell you what my power is. And we will see if your Nen can stand up to my abilities. Now, if you'll excuse me, I have to register."

She released his neck and moved to go around him. Hisoka remained pressed to the wall, his head tilted to the ceiling in relish. The trembling in his limbs, the burning taking root in his groin, the rush of blood in his cheeks as he touched the spot where she had him all flooded his brain. Bringing shaking fingers to his mouth, Hisoka touched the tip of his tongue. Licking the digits that had held her hair, he rolled his eyes back in pleasure.

"Oh, my little mouse," his voice came out in groans. "I will have you both in the arena…and out."
