Furi

You will get this trophy after beating the ninth boss. The Beat is very different from the usual bosses and for most of this fight you will be chasing her with the occasional stop. While you're chasing her, some orbs will be shot at you but they can be easily dodged. Once you reach the first circle arena you will be required to dodge and shoot, if any orbs are shot at you just parry them with the button. Once you hit her enough it will be some more chasing, as with the last time keep dodging any orbs coming your way.

After a little while you will find yourself at another circle arena. This time she and her drones will shoot bombs that will create large circles you will have to dodge. While you're dodging her don't forget to shoot at the same time. Shortly after that a small cutscene will play then finally all you have to do is hit her. She won't attack you, just keep hitting her until she dies.
