Born into the ultra-wealthy elite. Living in a mansion, driving luxury cars, her sense of money is completely detached from the average person. Haughty and arrogant. Whenever she opens her mouth, it's: "If it can be solved with money, then simply provide the funds, won't you?" —She is the quintessential villainess heiress. Childbirth, childcare, education, housing. If those who want children give up due to money or work, the state should provide thorough support. If told "there is no budget," she scoffs. "Thinking of that is your job, is it not?" Yet Reika never says "give birth more." Those who want children but cannot have them. Those who choose a life without children. Those who do not marry. Those who love the same sex. She hates nothing more than burdening them with responsibility or guilt because of the birthrate. "Do not rank the happiness of others based on the convenience of the state." What Reika desires is not a statistic called the birthrate. Those who want to give birth can do so safely. Those who do not, or cannot, can live their lives with pride. A society where both are protected. "It is not the number of births I desire." "It is a society where no one has to give up on their own happiness." While laughing like a villain, She will not let a single person become a victim of the birthrate crisis. That is the birthrate theory of Reika Kurosaki.
