neku and inu can be considered, but they weren't stronger than jack in zou so, no haki bloom. fuji and sengoku was an overkill
and luffy didnt get his haki bloom in his fight vs kaido rn. he just used coc same way he uses Adv. coa which he awakened in desperate situation when he was trying to free both himself and hyogoro from that exploding thingy
Honestly, I hate monthly releases in general. A lot of reasons behind it but maybe one is that I suck at remembering stuff, lol. I usually don't get irritated by bad OP chapters because they're weekly and I know that I have a chance of getting a good chapter next week. But when I wait for a month and then get a bad chapter... Oh hell no.
