Ghostbusters decide to shack up in Japan! They start taking calls for the curses in lieu of either jujutsu high schools. For the sake of argument, the ghost gear works on curses. How well do they do against curses!?
Round 1: The OGs Peter Venkman, Raymond Stantz, Egon Spengler, and Winston Zeddemore.
Unless I'm heavily missing something, Ghostbusters will actually lose this battle unless there's expanded material that has them be superhuman to some degree.
