In all honestly, what does have Nemu going for her besdes her character design?
She had not a single fight untill now, her character for 640 chapters consisted of a stoic stand on the sidelines hot chick.
"Everything " she ever did to progress the plot was to beg Uryu once not to go after Mayuri and give him the anitdote die and get revived immediately again.
That´s all Nemu did in 640 chapters with her screentime.
OOH noo hot chick sidecharacter no 5 dies.
Let her die and do something at least.
Remember Kira? Remember that we don´t know if he´s dead or not yet.
Kensei, Toshiro, Rangiku and that other guy whose name i forgott are confirmed dead. None of them got a touching backstory.
Which Kubo will revert most likely because the war had too many casualities till now especially fanfavorites.
