The Sun's Grace (KNY x Naruto)

One... More... Attack.... and the battle would've been done, Uppermoon 1, Kokushibo, Michikatsu, his brother, would've died. In the end however Yoriichi's aged body could hold out no longer, as all movement and signs of life faded from his body. As Kokushibo struck his brother's lifeless body down in rage he saw the small flute that he had given Yoriichi back when they were children, the realization of what he had done hit. However the story of the origin of the breathing styles did not end there it continued in another place, at another time.
