of course the phone is at zero battery in the moment of need, but for once it works, as MC isn't used to one he forgot to charge it, or the evil apparition made it lose energy
sensei is a weird adult, but is not bad
only thing I disliked abotu this chapter was MC walking to his death, he knows perfectly how vulnerable he is in a normal area, so a isolated mountain was suicide, teach even told to not go, he is a livng bait for monsters and spirits and didn't bring anything that could help
yeah, a bad chapter, the reasoning that it was made to show that the teacher is a good person doesn't counterbalances it
