I think Asat Pramad is gonna win in some way shape or form
Now by win I dont mean hes gonna destroy kill the whole crew (its still a gacha game) but he will still succeed in whatever hes trying to acomplish or he will do permanent damage to the crew/trailblaze
From the trailer besides the Himke Novaflare short showcase for the most part Asat is shown winning or in a position of power 80% of the time. Add to the fact that Nanook flashed on the screen and what looks like TB's life (plus their futures and alternate timlines) flashing before their eyes it doesnt look to good for us.
I think either Asat succeeds in his initial plan and he just leaves to torture the crew more or he fails in his initial plan but he kills a Himeko when she goes for some sacrifice play to save the rest of the crew.
Either way with how much their hyping up Asat (They gave him a solo Myriad celestia about his backstory) and with his connection and his power drawing from THREE PATHS I hope he doesnt go down permenantly in this 4.4, would be disappointing.
