Synopsis
After some kind of incident, modern-day Japan suddenly found itself connected to all sorts of other worlds. Elves, female knights, vampires, cat-eared girls, fairies, demon lords — they're all just wandering around Japan now. To give these visitors a place to learn, a special class called "Itoku" was set up. A boy named Yakuma Mamoru ends up as class representative, and from there his school life gets pretty packed — his otherworldly classmates keep leaning on him, getting attached to him, and somehow it all just works out into something really fulfilling.
