It's late at night and Ichiro is at home tinkering with his computer, working on upgrading his specs so he can conquer a massive queue of eroge he's got lined up for the upcoming summer break. But when he boots up the first game, a strange quake rocks his room and he blacks out instantly, only to wake up the next morning like nothing happened... Was it all a dream?
Before Ichiro can nod off again, his childhood friend, Wakaba, comes to wake him up for school. Ichiro has always been something of a night owl, and since he started living on his own she's been doing this daily as a favor to Ichiro's mother, who was so worried about her son living alone that she got him an apartment managed by Wakaba's parents—both close friends of hers. Ichiro is still sleepy and therefore grumbly, but with the school day about to start he reluctantly gives in.
During class, Ichiro falls sick and is taken to the school infirmary. His classmates jibe that his otaku lifestyle is ruining his health, and he tries to laugh it off. His habits have never been extreme enough for him to get sick before, though, so his friends, Wakaba and Meguru, are worried about him. Once he gets home, he boots up the same game again and before he knows it, it's already late at night… when the strange quake strikes again! He starts to panic. Maybe last night wasn't a dream?! Right then, a desk drawer suddenly opens, striking Ichiro square in the stomach. As Ichiro passes out from pain and shock, he looks around to see a mysterious light emanating from his open desk drawer.
So what's inside… a robotic cat? Is it a blue, robotic cat? But Ichiro's dreams of a talking robot pal are dashed. Instead, three beautiful girls appear before him, dressed as if they had stepped straight out of a fantasy game...
