Characteristics

The genre can be divided into two types and . In "transition into another world" stories, the protagonist gets transported to another world (E.g by traveling into it, or being summoned into it). In "reincarnation into another world" stories, the protagonist is sent into another world after dying in the real world. A common method of death is being run over by a truck and dying, spawning the meme of "

This can be physical characteristics, such as hair or eye color, or normal everyday skills they learned in their previous life such as cooking, engineering, basic education, or medicine, which are far more advanced in the modern, real world than in the world they are sent to.

'', an entire population of humans appeared in the magically created world, transported from Earth, and were partially mixed with local dragonlike Heavenly Beings. While the protagonist of a classic isekai work is usually a "chosen hero", there have been a number of alternative takes on the concept. One trend is the protagonist reincarnating into the body of an unimportant side character, or even a villain (as in '' My Next Life as a Villainess: All Routes Lead to Doom!''). There are even instances of protagonists becoming inhuman creatures, such as in ''
