After breaking open the mysterious door in the Tenba Labs, Lyner Barsett, Krusche Elendia, Jack Hamilton and Misha Arsellec Lune continued their way further inside into the building, looking for Misha's lost song, the Chronicle Key. Once there, Lyner entered to Misha's Cosmosphere, and saw how the Chronicle Key, represented by a ship, appeared into the Cosmosphere. This allowed Misha to obtain a new costume, the China Dress, and returned her to her correct age.
