Dennou Tenshi: Digital Ange

An Adventure game released in Japan in 1993. A guy goes out one day and happens upon a vagabond floppy disk. He takes it home, loads it up on his computer, and watches in amazement as a girl pops out of his monitor. Some giant mecha land outside his house; female pilots emerge from the machines and congregate with the disk-born chick, who can control the mighty pink mecha. They all hang around for a while, lounging, talking, and bathing. A few mean girls (including an unpleasant "copy" of the pink-mecha pilot) show up in their own giant machines.
