Just "finished" Vol. F (credit roll).
Man, the impact of that final scene felt a little muted from all the endless escalation before hand. I feel like there were 10 consecutive "it's so over, but we will all band together and we're so back!" moments that by the 11th time it wasn't special anymore. Still, that scene with the corrupted Sensei asking you to save Shiroko and you falling down from orbit as everyone watches still hit hard.
But honestly, what was that utter asspul from Rio the end? I guess she can just teleport people now.
