Based on the world of Naruto; Shou is reincarnated into the world of shinobi. He and his brother Haku lived peacefully in the snowy village. Albeit they are poor like everyone else, but they are happy. Shou discovered he could control body of water with his thoughts and will; and decides to warn Haku realizing his brother is the same Haku that ends up accompanying Zabuza and served him as a 'tool'. He does not want to believe it but the puzzles pieced too perfectly with the settings he was born into. He loved his family and brother very much and does not want their peace interrupted. Especially knowing Haku's fate he does not want his brother to experience such things. However, fate is unkind. Despite Shou's warning to prevent tragedy, fate played a cruel joke on all of them in different ways. Shou had no choice but to embark the path of Shinobi along with his brother Haku - raised as tools and subordinate of Zabuza.
