Eh, I was fine with having the chapter more dedicated to Kenpachi's conversation with Isane, his banter with Gremmy, and another demonstration of the extent of the latter's power. It was enough to at least see him get wounded. Skipping right to Kenpachi's Shikai (which is kind of a Big Thing compared to Yachiru's) would have made for some awkward pacing. Especially since I have a hard time imagining Gremmy lasting even a single chapter once the sword's name is revealed. Assuming that it will be, I mean; I wouldn't be surprised if Kenpachi could win this fight without it.
