You have no fucking idea how long Oda can stretch the "15 minutes until Onigashma lands".
He isn't tho
just look how the pacing has been in the last ~10 chapters alone
Luffy got power up, went down, back up again
Momo turned into a freaking adult Dragon
Zoro got down, back up again, fighting King
Sanji escaped from Black Maria and fighting Queen now
all F6 were up and now are all down
Oda is rushing past everything now
This really feels like it
Especially now that Oda already made Luffy lose 3 times against Kaido, the next one is over
and Sanji / Zoro fights never take that long anyway
