MegaMan StarForce 2

I defeated the guy who steals the friend in the cinema part of the game but I have no clue what to do next.

Go to shopping plaza, 2nd floor, talk to Mr Boreal(Amaken guy).

the part where you need to bust all ghosts? (I just noticed this!! it's a ghost busters crossover!!!)

Get the Wave Vacuum Cleaner.(I know, when i got it, i was like WTF!?)
