I only read the English edition so I'm half a dozen volumes behind, but I'm sad to stay I'm not surprised he piled on some more bullshit. Kubo is zo preoccupied with revealing twists and introducing new characters, he tends to forget about important stuff he's already written. Like, Chad was supposed to be a central character in the Fullbringer arc? I literally can't remember him doing anything important aside from existing, which is, now that I think about it, pretty significant, as Kubo often forgets he exists, so... yeah.
Well Chad did introduce Ichigo to the Fullbringers and then fought Ichigo for a chapter before being immobilized by the secondary villain by having his memories messed with to the point of his mind nearly collapsing....so he did something. Oh right he also gave Ichigo a clue that awakened Ichigo to his stupid looking Fullbringer form that was used for half of a fight!
To be (somewhat?) fair, the Fullbringer arc seemed to be very poorly received so based off of pacing it is highly likely that Kubo was forced to rush through it to get to the final arc. So a shitty arc was made even shittier!
Gotta say, I'm surprised so many of you still follow Bleach despite ragging on it so much. Like many I enjoyed it at first (really, the soul society story arc is still decent even today if you can consider it without all the baggage that followed...), but I haven't touched it in at least 8 years...
Eh it is included in Shonen Jump and takes like 2 min to read, so I have been reading it for laughs. If you go in expecting crap then you can get some B-Movie entertainment from the last arcs.
