Inoue's bratty little cousin Yuuki is visiting. She's trying to cater to him by cooking his favorite breakfast (fried eggs) every morning, but he complains about the awful taste every time! Amami vows to help Inoue cook the best eggs ever, but after consulting with a nearby ghost, she learns that maybe Yuuki wants something more than just better flavor?

When the gang sees a sleep-deprived Amami stumbling down the street, they worry her inability to ignore her spectral friends is putting her heath at risk. They decide to speak with her father Asahi, who digs up a special pair glasses capable of blocking Amami's sixth sense.

Amami heads to a theme park with all her friends, living and otherwise (and Yamada's older brother, for some reason)! According to her father, this particular theme park is the site of some fond memories for Amami, but now that she's older the memories have begun to fade...until a mysterious girl appears before her. Join the whole Re-Kan! gang as they make the most of a beautiful summer day, capped off with a sleepover at the Amami residence!
