## Background

### Early Life - Part I - II

Seia was born into the Hoshigaki Clan from a normal human mother and a full-blood Hoshigaki father. Since infancy, he was very knowledgeable and had a strong connection to the seas surrounding his village and always wanted to be near the sea. He was captured by a group of shinobi and brought to Orochimaru who researched him in Konoha. News of his capture spread throughout Konoha and eventually reached Naruto. He snuck into Orochimaru's lab one morning and saw Seia in a test tube and read the files that had information on him. Orochimaru saw this, and freed Seia and he and Naruto became friends soon after.

Weeks pass and Naruto notices something off about Seia and noted that he seemed "sickly". Naruto went to Orochimaru and asked him what is wrong with Seia. Orochimaru explains that he is dying and that he and those close to him know that Seia's body is transforming as he told them this and at some point told Naruto who he must have misinterpreted it as something else. Naruto becomes saddened beginning to understand as Orochimaru goes on to say that he and his subordinates saw it start to happen but don't know why. Naruto sees Seia soaking himself in the ocean Seia then stands up and notices Naruto. Seia proceeds to thank Naruto for the friendship he had with him. After a moment of speaking Seia begins shining and walking further into the sea clearly showing signs of ill health as Naruto yells out for him, Seia tells Naruto that "the time has come" and that he predicted it would happen during the day time before he could say more, he collapsed into the sea. When Naruto dove in after him clearly confused, Naruto watches his form beneath the water, and the form of Seia swims around him and lifts him out of the water. Naruto awakens on the beach coughing up water after Hiruzen Sarutobi lifts him from the water and brings him to Orochimaru who proceeds to say that Seia ascended into a new form and it's ultimate purpose is still a complete mystery to him, Naruto, and other shinobi and that they were simply not meant to know.

### Part III / New Era

Years later, Naruto, now as Hokage starts to remember a mysterious boy he met as a child and teenager and starts to miss him. News spreads that a mysterious, nude boy was found on the beach by his own son Boruto after the latter was walking alone by himself. Naruto is overjoyed and proceeds to tell Orochimaru who proceeds to tell Naruto that Seia's form must have resurrected itself and that he is pleased .

## Personality

Seia was a very mysterious boy who was smart for his age. He was truthful to himself and to those close to him. In some ways he was like Sasuke Uchiha after the Uchiha Clan Massacre quiet and arrogant. But over time, started to warm up to Naruto as a close friend as well as his son Boruto and the rest of Konoha's generation.
