Original Video Animation or OVA refers to special episodes of anime shows. This is where the serious storytelling happens. There can be action and fantasy but there’s more sex, drugs, and politics. If you’ve outgrown Shounen and Shoujo anime, then turn your attention to “Sienen” which is geared to people in their 20’s-50’s. “Shoujo” means young girls and caters to a young female audience.
The shounen genre typically caters to a young male audience.
