When Ash and Goh hear that a small town in Johto has been plunged into perpetual darkness, they’re off to investigate…and it’s true! For about a week, it’s been nighttime all the time. But a girl named Tiara describes some Pokémon she saw when it all started: Unown. They heard Tiara yearning for darkness so she could see her beloved Cleffa, who she believes is now a star in the sky. Along with Cynthia, Ash and Goh battle the Unown, and Tiara realizes her wish was selfish. Daylight returns, and the Unown show Tiara a happy illusion of Cleffa to help her say goodbye to her departed friend.
