Dandadan

Momo is a high school girl born to a family of spirit mediums, and Okarun is an occult fanatic. To settle an argument, Momo heads to an abandoned hospital famous for UFO sightings while Okarun heads to a tunnel famous as a spiritual hotspot.

Okarun is cursed by Turbo Granny, and Momo uses her newly found psychic powers to curb Turbo Granny from running out of control. Dawn breaks, and the two of them temporarily find shelter in Momo's house.

After Momo's grandmother temporarily suppresses the evil spirit within Okarun, she says that a game of tag may be the key to defeating it for good.

To settle the score with Turbo Granny, Momo and Okarun show up at the promised tunnel. They start the game of tag to pull the location-bound spirit away, and they managed to capture Turbo Granny using Momo's psychic powers.

Victorious against Turbo Granny, Momo and Okarun regain peace. They have gotten closer through the traumatic experience, but they find their relationship to be awkward. That is when Okarun discloses something important to Momo.

Momo, Okarun, and Turbo Granny search for the missing golden ball. They search all over the school and find out that a pretty girl named Aira is in possession of a ball. Perhaps the effects of the ball, but Aira can now see "invisible things" now.

Momo and Okarun manage to pull Acrobatic Silky away from Aira after a fierce battle. However, Aira herself had lost her life as a side-effect of being eaten by a yokai monster. Facing Aira in such a crisis, Acrobatic Silky has a surprising proposal…

The battle against Acrobatic Silky is over, Aira harbors romantic feelings stemming from how Okarun had saved her. As Momo, Okarun, and Aira's feelings intertwine, Serpoians make another appearance, and the three of them are trapped in void space.
