It doesn't look like she's dead, It looks like she just got grabbed. I mean, certainly grabbed in a harmful and rough way, but she wouldn't be thinking if she was dead, and if the author REALLY wanted to kill her right now, we would have seen her die for maximum emotional damage. But I'm pretty sure the author just likes drawing nanachi and faputa, so I'm not super worried that she's dead.
It's the waiting that sucks, now. Got our chapter, but it ends on a pretty huge cliffhanger this time. See you guys again in 3 to 5 months
EDIT: on an extra note, anyone else noticing the trend of Faputa negatively reacting to our white whistle host? She often hisses at her, which appears comedic at first, but is combined with suspicious glares from faputa when she is nearby. Somethings not right.
