Haruka Kaminogi’s plan to spend summer break goofing off with her friends gets derailed when she begins having visions of blue snow and strange figures.

Haruka is finally being used by La'cryma for their own diabolical reasons, but Karasu has other plans.

Yuu has decided to make it his goal to study in Tokyo, but Isami is in disagreement with him. Fukurou and Karasu are preparing themselves for a similar type of fight.

Haruka's worse nightmare comes true; Karasu and Fukurou start their dreadful battle, and she does not even know where to find them.

Haruka found an old video when she was younger. She looks around the town to find a tape that could hopefully play it, but in the process of it all, raiding units from Shangri-la have appeared, and Kuina has exploited his allegiance to Shangri-la.

Haruka deals with the concept of forgetting, as her memories of her grandmother are disappearing, and an old friend she had in Tokyo is unable to recognize her.
