DSA a.k.a Danger Service Agency is a organization who takes jobs that the normal police wouldn\'t do. Mikura, Harada and Kuro deals with terrorists, killer android, gang lord ect... They are willing to risk their lives no matter how dangerous it is (for a price). However, sometimes they are stuck with the lowest job because they desperatly need cash. 3 years after killing Momoi, Mikura sense that somebody from the past is gunning for her and the rest of the DSA organization. She begins to train a girl called Asami because they might need some backup if thing goes at of hand. Will Mikura and the gang lives up to their reputation by succeding in every mission thrown at them ??? Will Asami be any help to them ???
