Eureka Seven AO

Description: Eureka 7: Astral Ocean

Ao, the son of Eureka, lives on Okinawa. He comes into contact with Mark 1, which turns out to be Nirvash, his mother's mecha, which no one has been able to make it work since his mother used it. Ao ends up joining an organization called Generation Blue with Nirvash and helps fights G-Monsters/Secrets.

The story is set on Okinawa's isolated island of Iwado, which has seen a growing movement advocating a return to an autonomous government. Ao Fukai, a 12-year-old boy with a missing father, lives on the island with an old doctor named Toshio and is about to enter middle school. Ao's mother was taken away a decade ago by unknown individuals. Naru Arata, Ao's 12-year-old childhood friend and the story's heroine, lives with her father, older sister, and grandmother. She has a "Yuta" power awakened within her due to an incident when she was young. A mysterious entity called "Secret" suddenly appears and launches an attack on the Scub Coral lifeform on the island. Ao launches a certain military FP called "Nirvash" aboard a Japanese military transport in his fervent desire to protect the island.
