Izumi Sakibara is a bespectacled student recruited into the Miko Council to combat supernatural threats. She holds a firm conviction that UFOs and aliens are linked to the town's demonic invasions, consistently drawing parallels between paranormal events and extraterrestrial activity. Her combat talisman consists of Shinto ofuda paper charms, activated by calling out "secret weapon tachyon plasma boomerang." She exhibits a pronounced fascination with fellow council member Chika Yurikasa, frequently admiring Chika's appearance and attempting to hug or "glomp" her, actions that consistently provoke irritation and rejection. Her supernatural investigations employ photography to document unusual occurrences, a skill aiding in uncovering hidden threats or antagonistic identities. Despite others' skepticism toward her UFO theories, she persists in connecting the group's demonic encounters to extraterrestrial hypotheses. Her interactions reveal a contrast between eccentric interests and dedicated participation in Kurako Hieda's rigorous training regimen. She develops an unexpected connection with a Twilight Priestess—a dark miko adversary—through an internet bulletin board, initially unaware of the other's true affiliation.
