Upon arriving, she becomes fascinated by Angelic Layer, a high-tech battling game where players control customizable dolls called Angels through mental commands. The game involves strategic combat, with players competing in tournaments to advance through ranks. Misaki, inspired by a mysterious Angel named Athena, decides to create her own Angel, naming it Hikaru after her favorite manga character.
