After some time to rest, Tear thought about something he read in the book about Chakra when he was studying these ninja arts... Something about them having elemental attributes. Now, naturally, because the book told him, Tear knew that he had been using chakra for a great many of things without him even knowing so... Even before he came here. However, he had been using this for Soul Energy and his Soul Wavelength rather than Chakra, and therefore did not know how to use Chakra that well. So, to gain perspective of not only Water Chakra, but also how to use it first hand, Tear went to the Freshwater Sea.
"... If I meditate on my chakra points... Just as I meditate on my Soul and Soul Wavelength... Then I should be able to understand the flow of chakra just as quickly as with Soul Wavelength and Soul Energy... Not only this, but I will have a greater understanding for Water Chakra... As my entire scheme is based off of liquids..."
Naturally, he was referring to his Crying/Liquid Soul, which flowed just like water with almost no flaws. He aimed to do the same thing with Chakra one day.
"... Well. The book said that walking on water was a good way to let the chakra flow... I walk on water all of the time... Now, when I do it, I just need to concentrate on it..."
Tear chuckled to himself. He looked outward to the vast, barren ocean, then closed his eyes, his signature, deadly, nonchalant smile right there on his face as he took his first few steps on top of the water.
