9 Month's Training
Takahashi goes home to rest when he's stopped by Shiva.
"Takahashi, tomorrow I will be training you in chakra control," Shiva states.
"Why? I have perfect chakra control."
"Your reliance on certain chakra natures could become a weakness. What are your chakra natures?"
"They are Water, Wind, Fire, and Lightning."
"What about your nature transformation kekkei genkai?"
"They're Boil, Scorch, Ice, and Storm."
"Then why is it that every time I see you use ninjutsu its Nitric Release with the occasional Fire Release?"
Takahashi has no answer to Shiva's question.
"During this one month, I will help you learn the importance of using all of your chakra natures and show you how chakra control could be used for more than just conserving chakra when using a jutsu."
The next morning, Takahashi and Shiva go to their backyard for training.
"For your training, I will have you focus on a single chakra nature for 3 days, excluding nitric. The last 6 days of the month will be for teaching you shape transformation. This gives you 24 days to master your 7 nature transformations; let's begin."
Water is the first nature transformation Takahashi choose to master. He manipulates the molecular structure of the water to change it to steam and ice. This not only improves his mastery of the water nature transformation but his boil and ice combined nature transformations as well.
The next nature transformation Takahashi chooses to master is fire. He manipulates the oxygen of the fire to increase its heat, size, and range. This helps master the wind nature transformation and scorch combined nature transformation just as much as the fire nature transformation.
Following the mastery of the fire nature transformation, Takahashi masters the wind nature transformation, and the storm combined nature transformation. Takahashi barely masters the lightning nature transformation. For the last three days of nature transformation training, Takahashi uses the leaf-cutting method and similar methods to check his progress. The training method for water is to fill a closed jar with water then freeze the water without opening it. The key is to manipulate the density of the moisture in the jar.
The fire method is to light candles of various sizes from a distance without melting their wax. Lightning's training method is to pierce a variety of moving objects, such as leaves, feathers, and flies, from different distances. These two methods also improve Takahashi's accuracy and distance calculation ability. After completing the nature transformation training methods, he realizes that these methods are better than the ones he used before.
Nature transformation training ends and Shiva starts the shape transformation training.
"Shape transformation is an advanced form of chakra control. It changes the form and movement of chakra," Shiva Informs.
When Takahashi first began to train shape transformation he didn't know how to start. After thinking about it, he decides to try to learn the Rasengan. He believes that if he learns the Rasengan then it would be easier to train sharp transformation. Shiva recommends for Takahashi to use a water balloon and ball, but it's rejected. Other than learning the Rasengan, Takahashi also contemplates ways of developing a jutsu that utilizes nature transformation.
