I don't think you can unlock them, I think they're there as placeholders for the other seasons since they use more than 3 slots.
They're supposed to be for events that you guys didn't get (Mesoranger DDR thing and Happy Cool Time), so I guess they just blocked them out lol.
Mesoranger DDR? Like, falling arrows? Nexon why :(
there was probably a way to crash server/dupe/item gen with it
Pretty much :|
It has a nice BGM too..
Too bad that didn't work out (also that it appears to have the usual time-limit style thing which probably means 4/5 attempts would get "not enough competitors found"). Looks like a neat thing to coordinate with MS.
I dunno if it's the same Mesoranger event, but
I'm more curious about the "Super Weekend Ring <Stage 5>" and Unique Potential Scroll that's supposed to come from the 7D attendance event.
