[Kazu-kun]

Here's the synopsis from the movie's website. It's not the same from ANN. This one has more juicy bits:

Spoiler for kind of spoiler-ish synopsis:

That day when she was still young.
Her father, Ken, went to fight leaving a young Anemone behind and he did not return.
Regret was left deep in the small chest of Anemone who couldn't say goodbye properly.

Seven years passed. Anemone was in Tokyo, the battlefield of her father.
Humanity's hope was entrusted to Anemone as a member of the organization Acid to fight humanity's enemy, the seventh Eureka, Eureka Seven. Anemone sends her spirit into Eureka Seven.

What Anemone found in Eureka Seven was a young man named Dominic and a girl with blue-green hair called Eureka.
What does this encounter mean? And there's the figure of a boy named Renton that appears and disappears.

Dewey, a mysterious man who was captured by Acid predicts "The Eureka Seven you are watching is not Eureka Seven. Countless unnecessary worlds created and destroyed by a false god. It's a mountain of garbage"

When Anemone and Eureka met, all the truth becomes clear and the door to a new world opens.

Speculation time.

Spoiler for speculation:

I wonder if this "false god" the synopsis mentions isn't Ao. He basically created and destroyed many timelines at the end of Eurake Seven Ao, right? Maybe Anemone's timeline was messed up by Ao's crap somehow.
