This PlayStation 2 release removes the erotic content, but adds new CG events. The game focuses on four female protagonists and features the story that plays in pre-determined order of selection. The four female protagonists were reunited after being separated for three years during the closure of the academy they were all attending together. They soon find out that the time capsule they buried prior to going separate ways have been dug up and instead, they find a note saying that their former teacher took it and buried it someplace else. The four of them decide to find that time capsule. The visual novel element of gameplay is regular, consists of reading on-screen text with occasional choices and top-down navigation through the map of the school campus. After the original PC game, but before this PS2 port, the game also branched into OVA series and manga series.
