Okay, so I usually bail on filler, but everyone was saying this arc was good, and wow, that opening scene really snagged me. Watching Muramasa twist everyone's own power against them was such a messed up display, and honestly, seeing Komamura's huge Bankai just attack him like that made my jaw drop. I'm already so invested in these manifested Zanpakuto; it's almost heartbreaking to see them turn on their masters after all their history.
