After a few weeks of chasing Genma around the village, Rai finally cornered him on his break between meetings about the Chunin Exams. He said it was called, 'Reiki Ryu', or 'Dragon Aura.' He's still working out the glitches in the jutsu, but it is basically visible chakra concentrated into a small beam of light, it can be as powerful as the amount of chakra put into it, and aiming it at a vital point on the body, it can immediately become fatal. Genma had shown Rai what a certain amount of charka could do.
"The more distance, the more chakra you need to put into it. It becomes weaker over the distance, so it is more of a close-medium range combat technique." Genma told her after he did a small demonstration. "And with every action, there is an equal and opposite reaction," Genma restated the famous Law of Physics. When a certain amount of chakra was pushed into the beam, more than the user's weight, they would be pushed back by the power. Genma explained this to Rai. Genma gave another demonstration, though he dug his feet into the ground, he was pushed back almost a good meter; this was only one of the glitches that he was talking about.
After a few practice rounds with him, Genma had to leave, but Rai, being her stubborn and determined self, continued to work on the jutsu. Rai took off her konoha and let it hang around her neck. She regained her breath and wiped the sweat from her brow. She muttered to herself while she made the hand signs, "Of the dragon, dog, boar, hare, ram…" She paused and took in a deep breath and let it out. She made the sign of the bird, aiming the center at her target. She concentrated on the target, building up her chakra. "Reiki Ryu, Release!" She demanded. A small beam appeared, not even for several seconds before shorting out and disappearing. A pulse mark formed on her temple. She gritted her teeth and growled a bit. She did the hands signs repeatedly for roughly ten minutes, or less. She got frustrated. "Okay, that's it!" Rai spat. She got into a stable horse stance and vigorously formed the hand signs again. Once she hit the sign of the bird, a symbol appeared on her forehead, it looked like the Hiragana symbol for Chi. "Reiki Ryu," Rai yelled, once she felt the burning sensation of her chakra flowing through her, "Release!" As she stated that, crimson symbols quickly appeared and slithered down her arms to her hands, her back around to her front, down her torso and legs, and forced the chakra our from her hands into a beam.
The beam was bigger than she expected, it completely obliterated the target and forced her dug feet back about a meter plus a half. When she tried to release the jutsu, the beam imploded and caused an explosion. Rai was sent flying backwards and crashed into a body some odd meters away.
Asuma had been training Shikamaru nearby and heard the ruckus. The next thing he knew, there was an explosion behind him and he bolted to it without even thinking. He saw the plume of smoke over the trees and wasn't able to see a figure fly towards him. It collided with him and he caught it and skidded back about several meters. "What the?" Asuma stated as he glanced down at the limp form of Rai. Rai squeezed her eyes as she tried to regain consciousness. Rai opened her eyes and looked up.
"Ade?" She muttered to herself in confusion. Asuma looked down at her, equally confused. She squirmed and stood up, her hitai-ate falling from her neck. Asuma helped her balance herself.
"Are you alright?" He asked her. Rai held her head with her left hand.
"Yeah, I think so…" She glanced at her arm; her symbols began to fade away into nothing but her bare skin. She bent down and picked up her konoha.
"Are you sure?" Asuma asked, "That was a pretty nasty explosion." Asuma glanced in the direction where Rai had come from.
"I'm fine," Rai assured with a big smile, "Really!" She closed her eyes. She opened her eyes and walked away, as if nothing happened. Asuma stood there, scratching his head in mass confusion.
Later, Asuma told Kakashi about what had happened in the forest. Kakashi had a sneaking suspicion he knew who it was who taught Rai. So, he hunted down Genma in the missions room and confronted him. "Why did you teach her something like that?" Kakashi growled at Genma.
"She kept nagging me until I showed her," Genma sighed. "I couldn't get her to leave me alone." Genma looked up at the glaring man in front of him.
"And you still showed her?" Kakashi's voice raised slightly. He let out a breath. "How new is this jutsu?" He asked in a calm tone.
"There's a few bugs that need to be worked out, but that's basically it." Genma assured Kakashi. Kakashi raised an eyebrow.
"That's it?" He questioned.
"Basically," Genma shrugged. He looked to his right.
"No… Explosions?" Kakashi interrogated the poor Chunin.
Genma jerked his head back slightly, "Explosions? What?" He was surprised at this question. "Only if it's unstable," Genma explained, gesturing with his hand.
Kakashi almost stumbled over. "Baka! Idiot!" Kakashi could have knocked the senbon chewing Chunin out cold. He leaned forward and raged at him, "You, of all people, should know what she can do, and that she has an unstable control of her chakra!" Kakashi scolded. Rai had just rounded the corner and moved to the doorway of the room. "She's just a child! You can't teach her a dangerous move like that until she's able to control herself!" Kakashi glared at Genma, who glanced over Kakashi's left shoulder to see Rai standing in the door way, scared, confused, sad, and angry. Kakashi let out a breath and turned to see what Genma was looking at. "Rai…" Kakashi was in slight shock. He was caught off guard. "I didn't mean what I-" He stuttered.
"That I'm a child?" Rai asked. There was a bit of uncomfortable silence. "Is that what you think of me as? A child?" She raised her voice slightly.
"No, Rai it came out wrong." Kakashi tried to assure her.
"It didn't sound wrong to me." Rai glared at him. She turned the way she came and left.
"Rai wait!" Kakashi bolted to the door to catch her. He got to the door and looked to his left, but she was gone. "Awe, great…" He cursed to himself.
Rai had been sitting by the edge of the lake, staring out over the ripples. A presence came and stopped right behind her. "Listen… That didn't come out right…" It was Kakashi's voice. "I honestly wasn't thinking…"
Rai scuffed, "No, duh."
"I didn't mean what I said." There was a pause.
Rai lowered her eyes, "Is that really what you think of me?" Rai asked. She glanced over her right shoulder, "A kid?"
This knocked Kakashi off guard, "What? No I-"
"Is that all I am to you? Another mission, an assignment… a nothing…"
"No Rai…" He explained softly. He crouched down beside her, "You're not a nothing to me. You're my friend… my lifelong friend." He put an assuring hand on her shoulder. "I'm here for you." Rai glanced at him. "And I hope you're here for me too." Rai smiled slightly.
"I hope this doesn't ruin our friendship." Rai stated.
"It won't… It's just another bumpy road we had to take." Kakashi smiled. Rai smiled back. Rai turned and faced the lake.
After several minutes of silence, she spoke, "Hey Kakashi." He looked over to her. Do you remember when the Nikkei attacked us?"
"Yeah…" Kakashi recalled, "What about it?"
"Something they said stuck out as they were retreating." Rai stated, biting her lip.
"And what would that be?" He asked.
"They said, 'Master won't like this'…" Rai stated, "That bugs me for some reason." Rai shifted at the awkward feeling that crept through her stomach when she remembered.
Kakashi gazed out over the lake in thought. "Do you think they could possibly mean Nikkei?" Kakashi inquired.
"Maybe," Rai shrugged. "It's just I have a bad feeling about that."
"Well, as long as it doesn't concern you, then don't worry about it." Kakashi turned to her and smiled. Rai looked at him over her shoulder and his hand. She smiled. "Oh, yeah," Kakashi patted Rai's shoulder before standing up. "That reminds me, while I'm gone, could you watch over Sasuke for me?"
Rai shrugged, "Sure." She sat there, watching the lake, while Kakashi turned and walked away.
