Eleven-year-old Sara Werec's elder brother, Ralph, was sent to the frontlines of an interstellar war 130 light years away, and Sara vowed to reunite with him one day as a comrade. Five years later, Sara is a student at Grapera Space Armed Soldier Academy, training to become a Reasoner, a pilot of an advanced weapons system called a "Strain."

When the academy is suddenly attacked by enemy forces, Sara enters battle against a Strain that quickly overpowers her. After incapacitating her, the pilot reveals himself to be her Ralph. Killing all the other students and destroying the school, he disappears, leaving Sara to question everything she has ever known. Soukou no Strain is the story of Sara as she reenters training under a new name, now determined to confront her brother and make sense of her brother's actions.

Soukou no Strain is without a doubt one of the best sci-fiction series out there. The series isn\'t heavily focused on the war itself and between regular mecha battles but instead its primarily focus is on Sara Werc, on how she cope with the loss of her friends and the betrayal of her brother.

Clearly the first episode is what drives us towards the edge of our seats. With the lost of Sara friends and the shocking revelation of being betrayed by her own brother, it instantly give us the questions into why he betrayed her? what made him betrayed her? etc. and in addition, who ...

In the future there are giant robots (shocking, eh?). Humanity has been forced into a civil war (for some reason) and is battling each other in space (wow). There are two factions, arbitrarily named the Union and the Deague; about the only noticeable difference is that the Union uses robots called Strains, which have to be piloted by a cannon-fodder teenager--in this series named after characters from The Little Princess. The Deague is smarter and uses unmanned drones. Oh, yes, to pilot a Strain, you also need a mysterious black box which is the crucial plot element in this story.

So, there's Sara Crews, Cruz, Werec, ...

There's ideas of something that could have been good but the show either only mentions off handedly or brought ...
