Anime OK editorial guide
How anime genres work
Genre labels are shortcuts to expectations. The useful question is not which single box fits, but which promises the story makes.

Story genres
Action promises conflict expressed through movement; mystery organizes information around unanswered questions; romance centers emotional intimacy. A series can use all three without contradiction.
Demographic labels
Terms such as shōnen, shōjo, seinen and josei grew from manga publishing categories. They describe a target readership more directly than a fixed tone, art style or level of maturity.
Premise and setting labels
Isekai identifies movement into another world. Mecha highlights machines, often but not always in war. Slice of life emphasizes everyday rhythms. These labels can sit on top of comedy, drama or suspense.
Use labels as a route
Combine genre with tone and pacing: a quiet supernatural drama offers a different experience from a supernatural battle series. Browse the genre hub for a shorter overview.
