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.

Wielding Acrobatic Silky's power, Aira fights the Serpoians alongside Okarun and Momo. The frustrated Serpoians power up their crustacean-like minion.

Momo's childhood friend Jiji has come to stay with the Ayases. He explains that he needs Seiko’s help with some strange phenomena at his house.

As Momo fends off an attack in the outdoor hot spring, Okarun and Jiji panic over how to handle the mysterious room. Just then, the doorbell rings.
