S.A.D.F (Sadofu) -- "The Special Armed and Defense Forces".
This is an organization that protects the people that live in its country.

Two new troops were recruited into CUE this spring, which is a special forces unit composed of the best and most talented members from the S.A.D.F.

One of them is 18 year old Tsubasa Hayama. Even though she was a bit lost as to why she was chosen to be assigned to CUE, every day her connection with the other members deepened.
Around that time a series of incidents of random street attacks started. In order to resolve the situation the members of CUE were dispatched.

Something is happening in Tsubasa's body as she is running about...
A variety of blue colored lights fills her field of vision.
Wherever she looks is deep blue...
