When Hikari was younger he lived with both his parents and his grandfather. Hikari always loved to play as a pirate discovering ancient treasures, and expressed an interest in exploring the depths of the ocean. His parents played it off as just a child’s fantasy, but his grandfather supported him in ways that his parents never did, convincing him to pursue a future in Marine Archaeology, which was the closest thing to a pirate you could get. Eventually, Hikari studied all that he could when he was older, and successfully became the newest Rising Ultimate Marine Archaeologist after being invited to the Ultimate Banquet by Japan’s government. He’s finally succeeded in his goal, but in the end, will he sink or swim?

This is a supporting role.

Hikari is very kind-hearted and an optimist. He has a very calm yet friendly demeanor.
