To get this achievement you need to "Show all available sets of Garo gear to the disresputable priest"

So far i have shown the priest the Ninja and Machinist gear but my question now is, do you actually have to equip the Garo gear to show it to her? Because i really want the Makai Master title and i don't even have all classes at lvl 60. I can easily get the Garo gear for all classes, but leveling up all classes to 60 along with it? Come on.
