Izuna added, "You should be careful with the Rinnegan. You should not go around announcing your powers to everyone. I shall only train you to use the Rinnegan if you promise that you shall use its powers only when you need to save someone close to yourself or when you have no other option."

Naruto was getting excited. He knew that he shouldn't show off his powers to others. He told his father, "I promise to use the Rinnegan when I have no other option at my hand. Can we start training now?"

Izuna said, "Agreed. But first you need to work on your basic Kamui, Amaterasu, Susano'o and your Chakra armour."

Naruto was clearly not happy at this. He wanted to learn to use his Rinnegan but his father wanted him to first perfect his mangekyou Sharingan abilities. He understood why but he really wanted to master his Rinnegan. This blew away all his excitement and enthusiasm down the drain.

Izuna looked at naruto's sad-ish face and said, "Though your level 3 Susano'o more than enough for your age, your Kamui, Amaterasu and Chakra armour can use a little more practice. Now we shall practice these three over the first week then we can start on your abilities with the Rinnegan. Today and tomorrow we shall concentrate on your Kamui."

Naruto was happy that he could practice his Rinnegan abilities for two weeks in which his father would train him separately. All of a sudden a few kunai came lashing out at him. He did the only thing that came to his mind. Used kamui on all of them and thankfully he had succeeded. he saw Izuna grin. He made a mental note to himself, "Be all the more alert when tou-san grins in the middle of a training session. Else, you will find yourself dead in the next second.' While he made the mental note, about a hundred or more kunai just came at him. He tried his BEST not to die.

Meanwhile in Training Ground Three

Shadow clone Izuna smiled and told Mito, "I shall train you right over here. Before that, manifest your Mangekyou Sharingan. But be wary. If you use your mangekyou Sharingan too much, you will go blind and you will have to transplant the eyes of someone who is close to you by blood who has also manifested their mangekyou if you want to keep your vision intact. This is called the Eternal mangekyou Sharingan."

Mito was aware of her mangekyou Sharingan though she was perplexed about the fact that she would go blind if she overused the mangekyou and she had to take the eyes of a close blood relative if she wanted to keep her vision intact. She had felt her mangekyou the day of the Uchiha massacre. She immediately did as she was told. Her mangekyou was the same as his grandfather's before he had attained the eternal mangekyou Sharingan.

Shadow Clone Izuna sternly told her, "Try to cast Tsukuyomi on me."

Mito did as she was told. She channelled chakra into her eyes. She tried to use Tsukuyomi. Itachi had done it many times. She tried hard but she was completely unable to use it.

Shadow clone Izuna understood that Tsukuyomi was not one of Mito's mangekyou's abilities.

He told her, "I don't think Tsukuyomi is one of your abilities. Thus, I think Amaterasu and Kamui are the abilities of your mangekyou Sharingan. Try to send this kunai into your Kamui time space. Concentrate on sending this kunai into a Kamui time space."

Saying so, he took a kunai and placed it on the ground. He observed it carefully for results.

Mito once again channelled her chakra into her eyes and tried to make the kunai go to another dimension. A small swirl began in the position of the kunai. It was working. The kunai was starting to go to another dimension. But the swirl stopped and only a small part of the kunai had gone to another dimension. She got sad at the fact that her Kamui didn't work perfectly.

Shadow clone Izuna looked at her face and said, "Don't worry. You did your first time better than Naruto. He wasn't even able to break the kunai in his first go. Though now, he can probably send a moving kunai into his Kamui time space and break a huge tree into half like you just broke the kunai into two parts. You will also reach that level soon."

Mito was actually celebrating at the fact that she was able to do Kamui better than Naruto at least, her first go was supposedly better than Naruto's.

Shadow clone Izuna said, "This week, we shall concentrate on your Kamui."

Mito was excited to increase the extent of her Kamui.

Meanwhile in Training Ground Zero

Menma and Sasuke were brought here by two Shadow clones of Izuna. One of them took Sasuke to one part of Training Ground Zero and the other shadow clone took Menma to another art of Training Ground Zero.

The part of Training Ground Zero to which a Shadow Clone Izuna took Menma

Shadow Clone Izuna asked Menma, "What do you know about Shadow clones except for the fact that they take a lot of chakra?"

Menma casually said, "I don't know. Why would I know?" as though it was unnecessary to him.

Izuna hadn't been expecting anything else from Menma. He said, "Do you receive memories from your shadow clones when you use them?"

Menma was surprised. He said, "I do not remember anything of that sort."

Shadow clone Izuna made another shadow clone and called it Shadow Clone Izuna 2 and asked Menma to make his own Shadow Clone. Menma made one. Shadow clone Izuna 2 and Shadow clone Menma went to a place where the original Menma couldn't hear them. They made a bet which Menma won and then dispelled. Once they dispelled Menma jumped in happiness when he got to know that Izuna would later get him Ramen at Ichiraku Ramen. Shadow Clone Izuna didn't care about it for he knew this was inevitable as Menma would have clearly asked for Ichiraku ramen while going home.

Then Izuna said, "You see, there is a memory relay system in shadow clones. You know how to use them perfectly and keep them intact for a long time. You can also share chakra among your shadow clones." Menma was celebrating as though he didn't care about it. He perhaps listened to no other part than the memory relay system and chakra sharing.

Shadow Clone Izuna put his arm to his head and said, "Now we shall work on your Rasengan. Show me your Rasengan. Use it on the ground right over here."

Menma channelled chakra and concentrated it above his palm. The chakra started to take a spherical form. Soon it had a spherical form and Menma hit it at the ground. It formed a small crater which could be considered as a toe of some animal which was slightly bigger than a human. Menma looked up to him in a glorious way. Izuna sighed and told him, "That is not a proper Rasengan. It is too small to be called a Rasengan. The basics are the same but you need to concentrate a much more chakra for it to be called a Rasengan. Look at this," saying so, Izuna formed a rasengan in his hand. It was much bigger than Menma's. He hit it at the ground and it formed a huge crater compared to Menma's.

Shadow Clone Izuna told, "See Menma, though mine was only slightly larger, it had much more chakra than yours making a greater impact. You will have to do better than your rasengan for it to actually be called one. You need to channel more chakra into your Rasengan if you want it to be greater have a much greater impact."

Menma now put his head down in sadness. He then put his head back up and asked, "What should I do now?"

Shadow clone Izuna looked at Menma sulking and said, "You need to practice more, besides, the more you practice, the more bowls of Ramen I shall treat you to."

Menma was kind of sad but he was up to the challenge. He was getting ready to make a Rasengan when Shadow Clone Izuna said, "Use some shadow clones. You will be able to gain more experience faster."

Menma hadn't thought of it. He directly performed the hand sign for shadow clone jutsu and ten shadow clones of Menma popped up next to him.

All of them started practising the rasengan. All of a sudden, that side of Training Ground Zero became the loudest place in Konoha.
