@Mattthecat, about your question ''Btw can anyone tell me what the deal was with "Sudden Death" this time, especially Ayaka (and Mayama)? ''
I watched this live yesterday, when each member is eliminated, during this song, it goes like ''Nakayama OUT'' and such (as you know already) but when comes the elimination of Ayaka the voice say ''Yasumoto Giriseji''.
Google translate say this means ''Fair share'', so Mayama and Ayaka are in equality i guess.
"Giri safe" means "barely safe", by the skin of your teeth
Basically, if you watch the rest of Sudden Death performances, Yasumoto always (?) gets eliminated in the first round (facts could be wrong, but she always loses)
Last time, in one of the performances, can't remember where, Yasumoto got a "giri safe", but then the narrator said something on the line of "nah, as expected, out!"
This time, though, Yasumoto got her wish, multiple times, in a loop, as to say "you don't want to lose? here's the deal!"
(sorry I didn't see the question until like a month later lol)
