Jumping into it without looking at tags I was beginning to think by about pg 17 that the idol would become a monster of her own. I was pleasantly surprised that that did not happen.In case it wasn't clear, a Kunoichi is a female ninja. It's a yuri ending!
Obsessed parasocial fans morphing into literal animal monsters.
I was kinda expecting the big boss to be a unicorn (I guess this is more of a Western term that's roughly similar to gachikoi). Not sure if this was an attempt at social commentary on idol culture in Japan, but it feels kinda timely given the rise of Vtubers and Vtuber culture today has some significant overlap with JP idol culture.
