So Black Maria is still singing, when the music stops the act is 100% finishing and we should be close to it.
I really didn't understand the part involving Yamato, Sasaki seems clearly shocked with the transformation so it isn't something everyone knew.
And well the probability of we knowing stuff about the will of the D during chapter 1000 has increased A LOT.
Overall another good setup chapter combined with some action as well, wonder how the fight is going with the Scabbards with Kaido in his human form.
