意味

Original Video Animation — anime produced for direct home video release rather than theatrical or TV broadcast.

OVA (also written OAV) refers to anime released directly on home video without prior TV broadcast or theatrical showing. OVAs often feature higher production quality than TV anime, can contain more mature content, and frequently serve as bonus episodes or side stories for existing series. While OVAs were a major format in the 1980s-90s anime boom, they have become less common as streaming platforms have partially replaced the format.

例文
