OVA
An OVA, or Original Video Animation, is a type of animated work that is released directly to video formats, rather than being shown in theaters or on television. OVAs can vary in length and are often produced as standalone stories or as extensions of existing series. They are popular in the anime industry for allowing creators more freedom in storytelling and animation quality.
OVAs can serve various purposes, such as adapting manga or light novels, providing additional content for fans, or exploring side stories of popular characters. They are typically released in episodes or as a single feature and can be found in various genres, appealing to a wide audience.
