- And once again, Killua give a one-hit K.O! And in the ring next to it, Gon is doing the same! And what is this? Another rookie, Okamirei with her strong kick! All of three them have six consecutive wins in three days of participation! Killua with the sharp of his hand, Gon pushing them out of the ring and Okamirei kicking them senseless! How far will they continue to go like this? Who will be able to stop them?! -

"There's a hurdle in the one-hundredth floor." Killua said as Okamirei stared intently at the TV.

"It'll be fine," Gon said.

"I'm worried about you!" Gon glanced at him with a smile.

"Hey, I'm improving already!" Killua smiled slightly, then continued explaining the one-hundredth level. Okamirei just continued to stare at the TV. She still had her nightgown on, and she needed to change, so in mid conversation she left to the bathroom in haste and changed into her clothes.

She slipped off the green, see through coat/dress and pulled on the skirt and shirt, then tugged on the armband and leg band. She pinned her tail into place in her skirt and placed the ears over her own, pinning them in place.

"Aah! It's in six minutes! I'm going to be late!" Okamirei heard Gon yell from the other room. What was in six minutes? She quickly wrapped her hair in the loose ponytail and walked out.

"What's in six minutes?" She asked.

"Gon's fight," Killua replied. Okamirei had an 'oh' face on.

"When's yours?"

"Ten minutes. You?" Okamirei looked a little surprised as she pulled out her card which stated the time she'd fight.

"Same," she replied. She looked up at Gon who was just about ready to leave. "Good luck, Gon. Though I'm sure you'll do great."

"Thanks!" Gon replied, waving as he took off. Okamirei looked at her card again.

"I hope I don't have to fight you," she said, looking at Killua. He looked down at his card as well.

"Yeah. Though it's doubtful. Come on, let's go." The two headed out and walked down the hallway together in silence. Since Gon's fight was packed full of spectators, and Okamirei really didn't want to be in the same room as all those people unless they had to, the two stood and watched his fight on the monitor outside. Like always, one push and he won.

Okamirei and Killua didn't have to fight each other, and, just like every other fight, they won with one hit.

"We have an account!" Gon exclaimed. Okamirei just smiled as she saw how excited the two boys were. "I've never seen so many zeros before..." Gon's eyes were huge. Their accounts were huge also because of the money Okamirei had been putting into them.

"And to think last week we were nearly out of money. Well, except Okamirei." Killua said, glancing at the she-wolf. She just smirked back at him. He slightly blushed, but it went away as Gon spoke.

"I saw Zushi on TV yesterday." Okamirei looked at him as well.

"Oh yeah, Zushi..."

"He was still on the fiftieth level." Killua replied with a slight smile. "But I'm really curious to what that 'Ren' is." Okamirei glanced at him. Ren? What was Ren? "We will be sure to meet more guys like that up there." Gon cocked his head.

"Huh? Wouldn't it be better just to ask Zushi?" Killua froze, blinking, then started to laugh. Okamirei, too, was curious.

"Let's ask him!" She said, running off. The three ran with her.

"Ren is one of the four major principles." Zushi said. "One of the four major principles for disciplining your mind and body. Fundamental for every martial art!" The three's eyes were huge as they tried to process the information. "You must know 'Ten,' learn 'Zetsu,' achieve 'Ren,' and reach 'Hatsu!" Gon's head was steaming, Killua sweat-dropped, and Okamirei's eyes were swirling. "This is all part of 'Nen' training!" Zushi finished, holding up a finger. "That covers everything."

"I have no idea what you just said!" Killua yelled in his face.

"Zushi," Okamirei and the others turned to where Wing had started towards them. "Are you sufficiently educated that you can teach others? Gon-kun, Killua-kun, Okamirei-chan, there's an old saying that if you learn something piecemeal, you'll end up knowing less than when you started."

"So a little knowledge is a dangerous thing?" Killua asked. Sometimes it is... Okamirei thought, sweat-dropping. "But I want to know right now. Because it's related to the secret behind my brother's power." Okamirei looked at him in surprise, then turned back to Wing.

"Then, your brother is able to use Nen?" Wing asked. He glanced at Okamirei, then back at Killua.

"I need to know what Nen and Ren even mean! I'll agree to the full learning process rather than a quick explanation! And if you're willing to teach me, I won't try to figure it out myself." The two stared at each other intently.

"I understand," Wing said, lowering his head. "Come with me to my residence." The two left, and after a quick exchange of glances, the three headed after them.

The three stood in Wing's bedroom, facing him and a whiteboard. A bunch of words were written on the board. "Do I have your attention?" Wing asked. "Nen means to burn your own soul. In other words, it tests your strength of will. And the four major principles are part of a training curriculum for strengthening your will." Okamirei sat down on the couch, yawning. Why were humans so confusing? Why did they have so many words, and why did they have to use them all? It would make life so much easier if they just used simple words...

Okamirei started to nod asleep when her skin started to prickle and she opened her eyes instantly. She straightened herself as she looked in Wing's direction. Anger and the intent to kill was seeping from his body in unimaginable strengths. Killua looked terrified and Gon was scared. Okamirei started to growl as her nails sharpened and her eyes flashed a dull red grey. She snarled at Wing, ready to attack if he moved at all.

He flinched and Killua disappeared. Okamirei flinched as well, ready to attack, then dug her claws into her skin and closed her eyes to calm herself. The feeling disappeared, but she was still on edge. She opened her eyes to see Wing staring at her with an interesting look on his face, then turned and saw Killua attached to the top corner of the room.

"The concept of bluffing derives from this," Wing continued. Killua fell from the wall, glaring at Wing. "Ren hardens that which is soft, and you lose the ability to correct an incorrect idea." Okamirei looked at Zushi, who had a hard look on his face. "Therefore, you should avoid using Ren until your soul has fully matured. Right now, you boys," He nodded at Okamirei, "girl, and Zushi should be training your souls."

There was silence. "Let's go, Gon, Rei." Killua said, heading to the door.

"If you wish to learn about Nen," Wing continued, "you should focus on mastering Ten. If you do, you will no longer feel the pressure of an opponent's will." Okamirei scoffed. Pressure? Yeah right, it just strengthened me, almost making me lose control. If I was in a battle and someone did that to me, I would attack instantly.

The three left. "Thank you very much!" Gon yelled. Killua and Okamirei were walking next to each other and Gon was running behind, trying to catch up. "Wait up, Killua, Rei!"

The three walked back to the tower, silent. "He was lying." Killua said. Okamirei nodded her agreement.

"I saw it on Zushi's face, and I could feel it in the air," she replied.

"He was lying?" Gon asked.

"Yeah. The explanation made perfect sense, and Wing is clearly very strong, but his story had holes." Okamirei nodded.

"Huh?" Gon asked.

"Zushi's toughness. He kept getting back up after I knocked him down. I was getting irritated, so I used all of my strength during my last attack." Okamirei nodded her understanding. She would be in the same position if she had an opponent like that. "Willpower didn't keep him standing. He's hiding some other secret."

Gon looked like he was in thought.

"Killua." He paused. Okamirei and Killua waited for him. "Punch Rei."

"Huh?!" Both of them said. Surprised looks on their faces.

"If it's OK, Rei... I wanted to try something." He looked at Killua. "Punch Rei at full strength, just like you did with Zushi." Killua and Rei exchanged glances.

"I'm fine with it. I'm curious what your full strength is." Okamirei smiled. Killua sighed.

"OK." He faced Okamirei, then suddenly disappeared and appeared in front of her, sending a punch straight for her stomach. She grit her teeth in surprise as blood trailed out of her mouth, and she flew back a bit, raising a dust cloud. Killua looked surprised as well as Gon as they stared. Okamirei stood, holding her stomach.

"Ouch," she said, spitting out blood. "That was strong. I might have a broken rib." She walked forward a bit. Killua grit his teeth, then smiled.

"Yup, exactly like Zushi."

"Rei, do you know what Ren and Nen are?" Gon asked. She shook her head.

"I've never heard of them until now." Gon shrugged. Maybe his theory was off?

"Come on," Killua said. "We need to get back to the tower. I'll see if I can find a way to get you checked out, just in case, Rei,"

She nodded as she slowly followed the two boys. Wow, that actually really hurt, she thought.
