I'm convinced they translated all of these a month ago and are now releasing their entire supply of deadly ammunition.
So Hino makes leather things, which explains the train strap last time. But it also shows that she seriously makes everything herself. She also seems to live by herself. All of that smells of someone who learned to survive on her own.
Look... I may overlook molestation, groping, lecherous skirtflipping... BUT PUBLIC HANDHOLDING?
Not only are they fully aware of their shameful deed, they are even provocatively displaying it to the school! Hino even forced Koguma to tighten he grip... Sweaty palms getting intertwined, oh the depravity.
PS: I am not a fan of where that cliffhanger is going. Toilet play is a world that needs not be discovered in this manga. Ew.
