The radio and stage plays in anime referred to the adaptation of the content of animation or manga into sound plays (or dubbing plays) and stage plays that were broadcast on television or radio and watched live. Radio dramas referred to the adaptation of animation or manga content into sound and broadcast through radio stations or internet broadcasts. The audience could hear the voice actor's voice through headphones or speakers without actually watching the scene. A stage play was a play that adapted the content of an animation or manga into a script and performed in a theater. The audience needed to actually watch the performance and understand the storyline and characters through the performance in the theater. In addition to radio dramas and stage plays, other forms of works such as movies adapted from animated comics, television dramas, and various types of video games may also appear.
