I hate how Kubo
ALWAYS cops out of letting a character die
Kyoraku failed to kill Sado, Ishda gave up his powers (allegedly forever, I'm still kinda pissed he got them back (despite him being one of my favorite characters)) in order to kill Kurotsushi and failed, Aizen failed to kill Hinamori, then he failed to kill Hitsugaya.
Just recently (in the anime) Rangiku and Hinamori got one-shot, then saved and healed from the brink of death.
And the one that pisses me off the most...
The espada have been getting wiped out like flies, but never once has a "good guy" died
