After the success of their
first game, Studio OX (KSS was the publisher, they were the designers) came out with a 4 part OAV to accompany their second game. The second game largely follows that OAV's plot, and wisely chooses to make Mimu, one of the idols, the protagonist instead of a creepy manager. The game has been enhanced graphically and with more RPG style elements, including random encounters with fans on the world map. Control is still via the mouse.
