Seven years after a devastating earthquake that left Tokyo almost totally destroyed, Linna Yamazaki moves to Tokyo from the countryside where boomers are rare or non-existent and makes contact with Priss Asagiri twice, once after nearly being run over by Priss on her motorcycle and once while fighting a rogue boomer with Priss in her hardsuit. Megacorporation Genom has been producing boomers, a form of autonomous intelligent robot, to help rebuild Tokyo with manual labour where they appear as roughly humanoid, as well as menial service jobs and middle management positions where they are anthropomorphic. Occasionally these boomers go rogue and morph into a new shape while assimilating nearby machines and killing humans. Some anime violence and casual nudity. From ADV. WIth commentary by Thomas Safer.
