The isekai genre has become synonymous with the anime business, alongside bombastic fight sequences, blatant fan service, and adorable females doing cute things. The usage of reincarnation, a concept in which people are reborn into new bodies and identities after death, distinguishes Isekai anime.

They usually have their characters reincarnate into distant fantasy worlds full of swords and sorcery, thus some strange rebirths are unavoidable. Before the genre became famous, the soon-to-be hero would simply transform into another human, but with new writers in the game, the reincarnations are becoming increasingly unique, including ordinary mobs and even inanimate objects.
