After a long photo shoot, Japanese idol and bikini model Riho Futaba takes a break on the sunny beach of Minako Island, Okinawa. When an alien stings her, she falls; and awakens at a colossal scale! How will Riho use her new size? Is she going to search for help (and romance)? Conquer and destroy, abusing her new power? Or will she just have fun, in ways only a 48-meter girl can?

A retelling of the cheesy Simple 2000 budget game; and a tribute to older interactive stories with a similar concept!
