This adventure game depicts the life of three sisters. As the protagonist, Chris, you decide which of the three sisters you'll find a happy ending with. The outcome of each romance is entirely up to the player.
Living with the protagonist in a mysterious mansion are the three sisters: the easygoing eldest, Ai; the hard-working second, Mai; and the spoiled third, Mii. The story follows the protagonist as he gradually matures through his time with them.
The main game progresses through an adventure section where you can enjoy conversations with the girls. The story of main character Mii features a unique "music action section" where different storylines progress depending on your gameplay.
This is a port of the wildly popular PC version, and the PS2 version features new event CG, improved movement mode, and a newly written scenario. The beautiful graphics by character designer Poyon Rock remain intact.
Also included is a revamped version of the opening animation from the PC version, supervised by the same artist. The characters move along to the upbeat music, and even those who are not yet familiar with the world of "Popotan" will instantly become more and more fond of it after seeing it. (Eguchi Minato)
