九月に緊急に新曲出すそうです！_ゆれでぃの九月〜度 エンディング曲だってさ。
It's rumored that ayu will be releasing her 31st single in September. The line above says something about it being ayu ready?'s ending theme.
I'm not sure if this is true or not, considering how avex has been releasing information (well, bare information) on singles releases at least a month in advance (&, forgiveness). But it's possible.
credits - taylayu @ ayunite!
