This has all the hallmarks of this type of anime: the sexy fighting girls, the embarrassed, reluctant male hero, titanic battles, and a darling way of presenting young love.
Still, it pushes things a bit! There is the over-arching story of a city being ruthlessly controlled by a corporate Police State; not a government, but a megacorporation that soared to power after its founder discovered a hidden technology on a remote island.
But there is another part to the story: that of the BONDS of LOVE that can cause people to reach so deeply, and call so urgently upon their strength in order to protect those bonds, that something BRAND NEW can emerge -- something wonderful!
Even the WINGED (emerged) Sekireis are subject to all the usual frailties ... jealosy, selfishness, wickedness; but the BIRDS of LOVE, as they are called, will teach and learn about love ... as ordained by the Sekirei of Fate.
As usual, the question looms: "What will prevail? The disasters brought about by human shortcomings, or that which lies on the other side of the BONDS of LOVE? And are the Sekireis and their Masters willing participants in the GREAT GAME (The Sekirei Plan), or are they helpless pawns, subject to the whims of a power-mad meglomaniac?"
You decide; but the girls are lovely, the action is great, and the story ... well, after watching through season 2 ...
I want more!
... to be cont'd!
