I don't know but I hope its over. We got a little bit of Who's Who's backstory and his reason for fighting Jinbe aren't compelling at all to me. Jinbe beating Who's Who last chapter with Demon Tile Fist would be a good note to end on, i see no value of dragging it on any further and risk damaging the pacing of a what I considered a well-paced fight, which is rare.
I'll be more interested to see what CP0 plans to do with Who's Who and if Jinbe will have any other fights this arc (hopefully Jinbe vs Jack, Inurashi vs Jack is a fight i don't care about and with the fight happening off screened i care even less).
