She is Akira's childhood friend who has feelings for him and likes his new tougher persona(to a point). She never figures out that Akira is Devilman even though he talks/acts/is different than he used to be before his incident. She never figures out that Akira is Devilman even thought he transforms infront of her(she thinks its demon magic that made him go Devilman) and is alive at the end of the show. She has a cameo in Re: Cutey Honey for like a few seconds with Akira Fudo.
She is Akira's childhood friend who has feelings for him and likes his new tougher persona. She gets unholy things done to her by a demon at the beach but Akira uses his powers to make her think it was a dream. Near the end of the manga, Miki and her family are killed by crazed townsfolk who think Miki and her family are demons and her head is put on a pole. When Akira finds this he murders everyone there and holds her head in his arms in a memorable scene. After her remains are buried she is remembered by Akira and is alive in Violence Jack.
Here Miki is alive somehow at the start. She worked at the Resturant King and is Ryo Asuka's Girlfriend. They run away but get caught by the Slum King`s men while having sex. The Slum King removes her arms/legs and after parading them around town in the nude and tied up in an odd position. She still has sex with Ryo despite having no arms/legs. She is kept in the nude on a chain and collar and is repeatedly abused by the Slum King and his dogs. Despite having no limbs, she somehow helps Violence Jack kill the Slum King but is killed during the fight. After the fight, it is revealed that Miki was reincarnated as a dog, which had appeared in human form whilst alive.
In here, she is more comic like everyone in the OAV. She read the Devilman manga offscreen and knows about Akira Fudo's secret identity. she is captured by Gelmer and works with Sirene to help her but when Akira chooses her over Sirene, they (Akira/Miki) run. She knows about Mazinger Z, Kotetsu Jeeg and Grendizer when they go to the Mazinger world and when Akira is killed, she has a shock. At the end of the Chibi OAV, she appears in Violence Jack world thanks to Psycho Jenny and confronts Jack about him being Akira.
- She has a look alike (or maybe it is her) in Re: Cutey Honey for about a second or 2 with Akira(this is her 70s TV version of her in here).
