Attempting to FC RONDO's songs on EX (there's only one EX difficulty one right now) in D4DJ is the scariest thing I've done in my entire life. Currently, I'm trying to FC 瞬動-movement- and the chorus is impossible. Once Calendula's beatmap comes out, that's gonna be horrifying. To think that that song's beatmap is SO HARD that it's not even in the game yet.

Edit: Okay, I've gotten a hang of the first chorus now. It's now just the start of the ending chorus that gets me.
