So yeah, Yhwach turned to be stupid, as I forseen. Speaking of which -
OF COURSE he didn't forsee the arrow ...
he didn't see the future AFTER Kyoka Suigetsu(which should prevent him of being caight in it in the first place) even though he is supposed to be able to see EVERY possibilty >.>
So yeah, no need to complain now, last week chapter told us how it will go down.
OF COURSE he was so broken that the only way to defeat him would be to make him temporarily stupid, and Kubo delivered.
It's not like he has Yamamoto's bankai at his disposal even without his powers ;].
