>>656589>>656674Because those aren't the only songs in the live as was both exposed by Marine and Pekora at the very end of the A-chan totsu.
Daisensou was so heavily hinted at that it would be straight up false advertisement for it to not be that at this rate, and even if it isn't Daisensou then it is made obvious that there are more songs than what has been shown.
Marine, in an obvious hinting tone, brings up that perhaps Pekora in addition to others will be performing some other original song, and that it is a song in which the dancing portion is something she is really curious about how it will look, Pekora does her usual; "Well I wonder if it will happen" and then says that if it happens then for sure, she has been working hard on a certain dance she wants to show.
Then Fubuki practically nails the coffin down by saying that for her personally she thinks there is going to be a war(Sensou) at Bloom.
The last time it was nowhere near as deliberate as this, so I'd be extremely surprised if they didn't perform it this time.
