カヤ・バーグマンBiography
Kaja Bergmann is a ghost from Arashi's era and Arashi's best friend. She was an exchange student from Germany at the same school, and her polite, cool manner contrasts with Arashi's lively personality. Kaja shares Arashi's time-travel ability, but can form the necessary connection only with a living girl.
