Why oh WHY Can't I capture Hatsune Miku and make her part of my unit??? I have defeated her 8 times straight and even used two of my vocaloid units as a form of encouraging invite to join after defeat...why can't I capture her?? I have been waiting for a whole year for her return! And its her BIRTHDAY for cryin' out loud! Someone please, I beg of you, PLEASE give me some clues or unit tips on how to acquire the goddess of my dreams!! PLEASE!
