I use a dictionary and thesaurus, but sometimes I miss some mistakes. I didn't see your review as flame and I'm always open for constructive criticism.

Enjoy the next chapter.

At the end of the two weeks, Jiraya was through most of the books. Jiraya, Usagi and Naruto discussed the next steps. They decided that Jiraya should go back to earth and investigate. Usagi and Naruto should stay on the moon to train. They agreed upon a meeting point in a month. Then Usagi created a portal for Jiraya.

Now

The keepers, Naruto and Usagi were outside in the garden. Chika the mate of Takeru walked to them. They greeted each other.

"Today, you will start with training for senjutsu. Senjutsu allows you to sense and gather natural energy. You will be able to blend natural energy with your chakra and empower your abilities. By blending natural energy with chakra, senjutsu chakra is created. Senjutsu chakra allows you to enter Sage Mode, which enhances your combat efficiency. You are able to learn new techniques based on senjutsu chakra or to power up existing jutsus. Chika-san will train you in senjutsu. For the training you will stay with the wolves." said Akira.

They bade farewell. Chika led Naruto and Usagi to a training area of the wolves that was offside of the wolves living grounds. Yoshi, another sage of the pack, was already waiting for them. They greeted each other.

"Yoshi and I will teach you senjutsu. Akira-san gave you already a short overview of senjutsu, but there is more. Senjutsu has advantages, but also disadvantages, which you need to know before we start. In Sage Mode your physical strength, stamina, reflexes, perception and durability are drastically enhanced. Your jutsus become substantially more powerful. You are able to manipulate the natural energy that surrounds you. That means you can use it as extensions of your body to increase the reach of you attacks. You will gain the ability to sense chakra around. These were the advantages of the Sage Mode. Now I will explain the disadvantages. If you draw in too much natural energy, you run the risk of transforming into an animal and then into stone. In which animal depends on where you gather the natural energy. Here it will be a wolf. If the petrification is completed, it can't be reversed. That means you need to keep the senjutsu chakra and your chakra balanced. To gather enough natural energy for the Sage Mode, you have to remain perfectly still. Because of that you can be an easy target for your opponent. You can only gather a certain amount of senjutsu chakra. During a fight you have to move because of that isn't possible to replenish senjutsu chakra. That means you can't stay within Sage Mode for extended periods of time. It is possible that you are exhausted after Sage Mode, consequently vulnerable for your opponents." explained Chika.
"Do you want to start the training despite the chance to become stone?" asked Yoshi.
"Of course." said Usagi.
"Yeah." said Naruto.

Naruto was bouncing up and down. He was excited about the training. Usagi laughed about his antics.

"Ok, we will train you separate. Serenity-sama, I will train you. Please follow me." said Chika.

Chika and Usagi started with mediation. The mediation should help Usagi to sense natural energy. Usagi had no big issues with the mediation part. She had watched Rei several times during Rei's mediation for the fire reading and could use her observations. The empathy helped her to connect to the nature in a better way. After the first day, Usagi could sense the natural energy.

On the second day, Chika explained Usagi how to gather the natural energy. The next days, Usagi learned how to gather it and keep it in balance with her chakra. A few times during the training, Chika had had to channel holy chakra into Usagi to prevent the transformation into a wolf. After three days, Usagi was able to create enough senjutsu chakra to enter Sage Mode. At first, it was an imperfect Sage Mode, because she adopted many characteristics of a wolf. Her fingernails grew and formed claws. Her eyes became wolf-like that means angular with yellow eye color. A silver shadow appeared around her eyes. The features of her face appeared wilder than normal. But she got the hang of it after another day. At the end, she got only the wolf-like eyes and the silver shadow around the eyes.

Naruto had more problems to learn senjutsu. Yoshi and Naruto started also with mediation, too. But Naruto didn't get the hang of sensing natural energy. After four days, Yoshi stopped the training.

"Naruto-kun, Jiraya-kun told me that you have signed the contract with the toads of Mount Myōboku. The toads have special oil that allows the natural energy to enter the body. This could help you to get the hang of sensing natural energy. We don't have such a device. Maybe, you should continue the training with the toads. Could you summon one of the toads to ask." said Yoshi.
"Sure."

Naruto bit in his thumb and laid his hand on the ground. A seal appeared on the ground around his hand and Gamakichi was summoned. Gamakichi looked around and his eyes widened.

"Ey Naruto, where are we?" asked Gamakichi.
"On the moon." answered Naruto and scratched his head.
"On the moon!?"
"Let me explain, little one. I'm Yoshi a sage of the Lunar Lupus. We are on the moon. If you look behind you, you can see the earth." said Yoshi.

Gamakichi looked first at the huge wolf and then turned around.

"Ok, we are on the moon. But why?"
"Naruto-kun came with Serenity-sama and Jiraya-kun to train and investigate. They are here for almost a month. The last three days, I tried to teach him senjutsu, but he hasn't made any progress. I know that the toads of Mount Myōboku have special oil that can support the senjutsu training. Could you please ask one of your sages whether Naruto can come to Mount Myōboku and learn senjutsu from them?"
"It doesn't surprise me that Naruto has problems with the training… Sure, I can ask Fukasaku-sama and Shima-sama, our Great Sages."
"Fukasaku-san and Shima-san are cordially invited to visit us. Serenity-sama would create a portal for the travel."
"Ok, I will go back. Naruto, summon me in a day. This should be enough time to clarify this."

The next day, Usagi created a portal to Mount Myōboku. She went together with Naruto and Gamakichi through the portal. On the other side, two small toads were waiting. They were only 10 inch tall. One toad was a male with a dark green body color. The hair of him was grey. The other toad was female with a light green body color. Her hair was violet.

"Welcome to Mount Myōboku. I'm Fukasaku and this is my wife Shima."
"Hello Fukasaku-sama and Shima-sama. I'm Serenity and this is Naruto. It is an honor to meet you."
"Likewise, Serenity-sama. Naruto-kun, we heard a lot about you from Jiraya-kun. We would like to train you in senjutsu. Jiraya-kun mastered senjutsu and we are curious whether you will master it as well." said Shima.
"But first, we should go back. Takeru-san and the sages of the pack are waiting for us." said Usagi.
"Lead the way."

They walked through the still existing portal and arrived at the grounds from the pack. Takeru, Chika, Yoshi and the Lunarian keepers were waiting for them. They greeted each other. The next few hours, they were sharing knowledge. They decided that Naruto was going to come along with the toads to Mount Myōboku to start the senjutsu training. Usagi was going to train with Chika. Then she was going to follow to train with the toads and Naruto.

Fukasaku and Naruto started the senjutsu training the next day. With the toad oil and shadow clones Naruto got the hang of the senjutsu chakra after three days. Naruto could gather enough natural energy to enter Sage Mode, but an imperfect one. Toad-like traits were visible: toad-like eyes, bigger nose and warts all over his skin. Fukasaku had a staff to knock out natural energy from Naruto to prevent his transformation into a toad. He needed to use the staff a lot on the first two days.

Afterwards, they started to mediate. Naruto needed to learn to gather natural energy without toad oil. He needed a week to master it without the oil. With the mediation he was able to enter a perfect Sage Mode that means he got only toad-like eyes with orange eye color and an orange shadow around the eyes.

During that week, Usagi arrived at Mount Myōboku. She was happy to see Naruto again. She had missed him, but she didn't want to interrupt his training. Shima started to train Usagi. They started with Frog Kata. The practitioner used the natural energy around him to create an aura as an extension of his body. Only persons who are trained in senjutsu can see this aura. After a few days, Usagi and Naruto started to train together supervised by Fukasaku.

This was only a short chapter, but the next chapters will be longer. So far the chapters belong to the introduction, but I will start with the story line soon. In the next chapter they will return to Konoha.
