Yeah, the Single-V of their latest single isn't even released yet, that's also why I'm like "5th single already, really?" in the first post
I don't know if there is a new season starting in November ? But iirc it should be February shouldn't it? Well good for them and even better for us if they release more singles. Maybe it's not for the anime this time, they could try a different scheme for the song for the first time
