Finally, after 5 1/2 years since I came to watch and conclud Eureka Seven I got to start the sequel.

With just the first time around I couldn't get all the details in the first episode.

Spoiler:

I understand that Gazelle's gang were to deliver important goods while avoiding detection from the Japanese Army but fail to deliver all the contents; the missing one resulted a bracelet found by Ao which at the end of the episode triggered within him his lost memories about likely his mother, whom he remebered as Amber and a promise made.

The phenomenon happened at Iwato island saw witness to a return of a Scub Coral, which later births into a G monster type looking after just wanton destruction with Ao now stucked amidst a mayhem of carnage and destruction.
In a single day and night, Ao's everyday and normal world changed drastically.
