A/N: I really hope that the first chapter was better than the former version. Hope you'll like this one too.

Disclaimer: I have nothing to do with the Naruto franchise.

Undeniable

Rioko sat motionless in his chair, his eyes darting back and forth between his sensei and the hokage.

"Itachi..." Sarutobi began "...if this is true and you are correct, Rioko could be a danger to those around him and himself. It is essential that we determine for sure whether or not Rioko possesses the Naitekime no kokugen and take the appropriate measures."

He looked over at Rioko and said "Rioko, I'm going to have to ask you to remain here for the time being. Itachi, I need you to use your Mongekyo Sharingan to examine him."

Itachi looked at the hokage in shock "But Hokage-sama! The damage that could do to him is immense!"

"And the damage if we didn't could be even greater! We have no choice."

Itachi bowed his head in defeat and walked over to Rioko. "Rioko I'm going to need you to look into my eyes, it'll hurt but I have to do it for your own good. Do you understand?"

Rioko nodded and Itachi went through a series of hand signs. As Rioko looked into his eyes they began to change and his head began to hurt. At first it was barely noticeable but then it began to grow until the pain began so great that it felt like his head was going to split in two. Just as he felt that he couldn't go on, it stopped and Rioko slumped back in his chair.

Itachi got to his feet and looked over at the Hokage. "There's no doubt about it, he has it."

Sarutobi sighed and said "Very well, take him home but tell his family what we've learned. I also want you to keep and eye on him as much as you can. He will need training to control it and I need you to do that."

"Hokage-sama, I understand how important this is but I have other students that need training."

"Then you will need to train him individually when you are not working with the rest of your team."

Itachi bowed and then went to help Rioko up and then they both left the Hokage's office.

The next day, Itachi and Rioko stood alone in a training field looking at a practice dummy. "Rioko," Itachi said from his vantage point on the tree "I need you to try and recreate what you did yesterday, the fact that you were still conscious after that astounds me because of the amount of chakra it takes. I've done what I can to fully activate your kekkai genkai but you'll have to deal with the rest yourself."

Rioko looked up at him and asked "So what's it called and what was that about the Naitekime no kokugen?"

"The Naitekime no kokugen is the jutsu that the kekkai genkai allows you to perform. Your kekkai genkai is the Kokugan, now try to recreate your Raikosuru from yesterday." Rioko nodded and then faced the dummy.

He started going through the hand signs then felt a sudden rush of power surging through him and his eyes began to sting but not as badly as yesterday so he kept them open and saw the lightning forming around his hand. He looked around and saw that another change from yesterday was that everything was going even slower and even though Itachi was jumping out of the tree when he started, he'd barely moved.

Rioko then turned his attention towards the dummy and charged it. His lightning charged fist connected with it's stomach and Rioko cut of his Kokugan and everything returned to normal speed and he looked at his still crackling which ha gone right through the dummy and then the dummy exploded in a shower of wood chunks and sparks.

"Itachi landed and came over to him and said "I'm impressed, you were able to recreate it and went even faster than before. Last time I could at least see a blur but this time I couldn't see anything."

"Why was I able to go faster?" Rioko asked.

"I think your kekkai genkai allows you to adjust speed and this time you had more chakra to put into the start of it so you started faster." Itachi replied. "Now come on, your not my only student, we need to go meet Anko and Kakora."

__________________________________________________________________

Itachi and Rioko appeared at the training field to find Kakora manipulating her puppet to block kunai that were coming from every direction. Right as it moved to blocked another one, Anko came out right behind it and slammed into Kakora causing her to lose focus.

Then they noticed Itachi and stopped fighting and Anko said "Hi Rioko."

Rioko smiled and replied "Hi Anko!"

Itachi walked over and pulled Anko off of Kakora and Kakora then sealed her puppet in its scroll. "Where have you two been?" She asked.

"I was working with Rioko on a new skill he recently obtained." Itachi replied. "I think you may regret wasting your energy on each other with what I'm having you do next." The three of them remained silent and Itachi continued "I'm not showing favorites here I just want it to be fair s I'm having the two of you face Rioko and Rioko you are obviously not allowed to use you Raikosuru." Then he walked to the edge of the clearing and jumped into a tree and shouted "Begin!"

With that Kakora and Anko charged him from both sides. Rioko smirked and muttered "Kokugan" Then he looked at Anko and she gasped. When he looked at her she saw that the iris's of his eyes had gone black and the pupil was surrounded by a blood red symbol that looked like the biohazard symbol.

Then the world around Rioko came to an almost complete stop. 'Hmm...cool lets try that speed change thing out.' Rioko thought. And he began to urge time to move faster while he walked past Anko. He turned around and saw that everything was beginning to move faster. Rioko released his hold on time but kept his Kokugan activated and decided to test something.

The first time he had used the Kokugan he had closed his eyes but still been able to see. So he closed his eyes and was pleased to see that he could still see the world around him just with a blueish tint. He opened his eyes again and burst out laughing when he saw the looks on Anko and Kakora's faces. They charged toward him again and he slowed down time again this time running at Kakora and punching her in the stomach and then returning time to normal. Kakora let out a surprised gasp and then dropped to the ground unconscious. Anko turned towards him again and Rioko didn't even bother to slow down time, he just hauled oof and slammed her in the face. She went flying ten feet and landed on her back. She looked over at Itachi wincing and said "I give." Then her head dropped back down looking at the sky.

Itachi revived Kakora and then addressed the group "Rioko, that was extremely impressive. I saw you testing the different speeds and 'm very proud of the progress you've made in just a few tries. Kakora and Anko, while their was virtually no way for you to figure out where he was going, I thought that at least Anko should have been able to hit him considering he was right by you."

Anko looked at the ground, ashamed and muttered "He surprised us."

Itachi smiled and said "Yes I figured as much. However, none of you can afford to let surprises take you off guard in a real battle or it could mean your life. Now, you can all take the day off. Despite what you may think, I am very proud of you all."
