DAN DA DAN: First Encounter (Japanese with English Subtitles)

Momo Ayase is a high school girl who believes in ghosts but not aliens, while her classmate Ken Takakura believes in aliens but not ghosts. In a bet to determine who is correct, the two decide to separately visit locations associated with both the occult and the supernatural—Ayase visiting the former, and Takakura visiting the latter. Ayase is abducted by a group of aliens who accidentally unblock her chakras, enabling latent psychic abilities. Meanwhile, Takakura is possessed by a spirit who takes over his body. By using Ayase's abilities and Takakura's possessed form, they defeat the aliens together. The rest of the story follows the two as they attempt to cure Takakura's curse, fight spirits and aliens, and develop romantic feelings for each other.
