Future Card Buddyfight Battsu: All-Star Fight

Kitarou, a ghost, spends his afterlife helping humans in need of his skills. He thwarts the plans of evil spirits who live to torment humanity.

Shoko and Maiko Ougi are apparently two ordinary schoolgirls in pursuit of graduating and having fun. Shii-chan is the more serious while Mai-chan is more fun-loving. In reality, the two sisters are powerful exorcists from the Karura temple. Each wields half the power...Shii-chan can "see" the spirits, and Mai-chan can banish them. This is the movie adaptation of a spooky series with heavy emphasis on traditionally Japanese occult themes. (Source: AnimeNfo's Karura Mau OVA description; modified)
