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!
