Oreine

An original world setting; magic coexists and integrates with technology, elves have migrated to the mainland from an island that got submerged in such a dramatic fashion it became the starting point for counting years, so it's currently 11XX or 12XX year after the elven island catastrophe; everyone who isn't an elf or a human (or a faunus) is called "demon" though initially it was referring to either individuals who got into this world through dimension portals or their descendants; about half of the population has magical powers, most have enough magical affinity to interact with furniture.
