Good chapter. First in a while, which means we've got about a month or two of really bad chapters ahead of us now.
Interesting how people seem to think Kenpachi is weak now. Kenpachi is a straight up melee, brute force fighter and this particular enemy cannot be beaten by straight up melee, brute force fighting. It does not make Kenpachi weak, Kenpachi is still quite strong actually, but these Sternritter are powerful and have unique abilities that give them certain advantages/disadvantages against the Soul Reapers. This is a fight for Mayuri, a fight that requires tactics, strategy, and intelligence. Kenpachi will get his fight later, I'm sure. Besides, he didn't even put 25% of his power into this one anyway.
