Mira is the shiba inu dog from the Dog Ending of Silent Hill 2, as well as the UFO Ending of Silent Hill: Origins and Silent Hill: Shattered Memories. She also appears a playable character in Silent Hill: The Escape and as a hostage in Silent Hill: Book of Memories.
Since Mira only appears in joke endings, she is not considered to be a canon character. However, it is still possible that Mira exists in the main video game continuity in some way.
