Background

Shui Daiyi serves as the foremost disciple of Asao Jun, the Grass Shadow. He accompanied Asao during an inspection of orphanage children for ninja talent, but neither he nor his master considered the selected candidates noteworthy. 2

While leaving the orphanage, Shui noticed the unusual chakra surrounding the five-year-old Yuexia Ming. Concerned that the child might pose an unknown threat, he approached Yang directly and questioned him with suspicion. Yang's ensuing display of Monstrous Strength left Shui stunned and convinced that he possessed extraordinary potential. 3 4

After Asao Jun chose Yang personally, Shui was assigned to collect and guide him. He came to view Yang as the future hope of the Grass Ninja Village and treated him with pronounced respect despite Yang's age. 4 12 13

As Yang's standing in the village rose, Shui became a regular intermediary between him and the Grass Shadow. He personally delivered summons when Asao required Yang's counsel on urgent matters and treated him with the same ceremonial deference normally reserved for the Grass Shadow. 61 103
