Maaan this episode is easily demo quality in the art & animation department with some very strong directorial frourishes. There is also an unsual amount of attention to detail in this, such as the glow around Sabo & Fujitora during their fight and those great touches added to Bartolomeo. Barto's filler scenes in this one are downright mental (and that's what I love about them). Strangely, Diamante is the worst looking aspect in the whole episode.
Sadly, the pacing is still 12 pages per episodes (out of a total of 18 per chapter) again taking into account double spreads. It's not too noticeable up until Barto takes those bomb blasts, then the episode slowly wraps up for three whole minutes laboriously eating up the required time. The whole episode has bits like this. Since these pages were high on action, this episode struggled to fill it's required episode length.
However, the superior technical quality of the episode makes it much easier to swallow and enjoy for what it is.
696 looks like it has a similarly high standard, but this episode will be tough to beat.
