Momo believes in ghosts. Okarun believes in aliens. To make each other believe what they deny, they head to a spot famous for UFO sightings and a spiritual hotspot.

Momo awakens psychic powers, while Okarun is cursed by Turbo Granny. They evacuate to Momo's house, but a giant alien appears before them.

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.

Okarun and Momo arrive at the tunnel to confront Turbo Granny. Just when they think they've won, a giant crab spirit crashes through the wall.

Turbo Granny reveals that Okarun's missing organs are contained within golden spheres. Aira, who has found one, now has the ability to see spirits.

On the way to investigate the Enjoji house, Okarun feels uneasy about Jiji's closeness to Momo but finds himself drawn to his friendly nature.
