Shoko and Maiko Ougi appear to be ordinary schoolgirls focused on graduating and enjoying life. Shii‑chan is the more serious one, while Mai‑chan is fun‑loving. In truth, the sisters are powerful exorcists from the Karura temple, each wielding half of their combined power: Shii‑chan can see spirits, and Mai‑chan can banish them. The series is spooky and places a strong emphasis on traditional Japanese occult themes.
