When she was in middle school, Kurumi Fukuga's mother Kozue became involved in foreign exchange (FX) margin trading. However, Kozue had secretly been using the family's money, which caused her to lose 20 million following the bankruptcy of Lehman Brothers and its associated fallout. Unable to bear with the losses and their possible effects on their family, Kozue commits suicide, devastating Kurumi. Vowing to avenge what happened, Kurumi spends her high school and university years becoming interested in FX, hoping to earn back the 20 million her mother lost. Despite some early successes and her good intentions, she realizes that margin trading has its consequences.
