I actually expected all the people swallowed by the slime, being all alive and freed after defeating the slime which ate them... (Kinda like in e.g. Spirited Away)
So they just died like that? Damn that's actually pretty dark.
Also, MC saved the lives of 2 of the teachers, and I don't think they even processed that all how close they were to death, let alone even thanked him? They should learn being more mindful grateful.
Thanks for the update
