Shino's morale must be rock bottom right now. From getting pressured by a love rival, to unknowingly carrying a tracking device and getting saved by Iroha sacrificing herself. She must feel isolated by now. Hopefully, MC will get a moment with Shino again because it's overdue.
Io's mom was revealed as the leader of AUNG. The author got that revelation out of the way fast but still nothing about the missing adventures! AUNG probably kidnapped them to do experiments, but hopefully, we'll get a lead about them soon.
Anyway, this is the end of Act I. Judging by the raws, it looks like Act II is taking the plot into a whole new direction. I'm curious if the story will still have wildlife survival elements instead of just mainly focusing on AUNG and escaping back to Earth.
