I'd like to see a story about a previously ordinary class of schoolchildren who've returned from an Isekai adventure back to only a couple of hours after their departure. From the point of view of the parents, teachers and other adults who have to deal with a group of armed (having an item box ability would make the story MORE interesting, as you could never be sure they were unarmed) and mildly superhuman people who've spent a subjective couple of years in a war zone in a different culture.
They've picked up odd habits like only being able to sleep if they have a dagger underneath the pillow, odd religions and one's brought his succubus girlfriend and baby daughter home . . .
