There she blows! Blowing the choppers out of the way.
Matsu powers up with norito and uses her power to temporarily take control of Kouten from Maya. Matsu then uses Kouten to literally blow away many of the enemy helicopters before Maya takes back the controls. Tsukiumi also powers up with norito to deal with the enemy ships on the sea. The invaders still manage to land some troops on the island, and they capture Sanada and uses him to threaten the other Ashikabis and Sekireis. After a discussion, Minato, Natsu, Higa and Mikogami come to an agreement to get rid of the invaders and carry out the Sekirei Plan, and so they all head to the middle of the island and rescue Sanada from the invading soldiers.
When Matsu mentioned something about Kouten, I didn't think she would try to take control of the flying island. Kouten has some potent powers, but it doesn't look like Maya is going to do anything to help the people on Kamikura Island. I guess to make it up to Kouten, the Ashikabis and Sekireis will have to earn their way up there by beating the invaders. The Ashikabis have formed a temporary alliance as expected. The invaders are numerous and have military equipment, but those things aren't all that effective against super-powered Sekireis, so I wonder if the invaders have any tricks or special equipment up their sleeves.
