Satoru Wamiya (和宮 さとる, Wamiya Satoru) is one of Izumiko Suzuhara and Miyuki Sagara's classmates at the middle school in Izumiko's hometown. It is revealed in Episode 3 that Wamiya is Izumiko's familiar, created by her desire to make friends.
Wamiya has two known forms: his human form, and his familiar form. In his human form, he is almost the same height as Izumiko, with very pale skin and black hair. His eyes are black and sharp. As a familiar, he appears as a crow.
As the show begins, he has a calm and friendly personality. He complimented Izumiko and often had small conversations with her in school. But as of Episode 3, you see he has a possessive "yandere" side. By wanting Izumiko's attention to only be on him, he attempts to stop her from moving schools, threatens and fights with Miyuki, and causes Izumiko to be in a dangerous car accident in order to stop her from leaving.
Izumiko Suzuhara Edit
Wamiya is Izumiko familiar, which is why he always observes her. He was also the one who complimented her on her new hair cut when the other guys in her class were making fun of her.
Transforming into a crow
Wamiya goes to the same school as Izumiko before she enrolled to Hōjō High School in Tokyo.
