Her character is very simple and easy to understand.

Mizuho Fukusima is a Japanese minister.And She has just been dismissed now because of the problem of U.S Army facilities in Okinawa. 
 What she says is interesting but has no influence among people.The more eager she is the less interests with her people have.
 Ironically She believes in American constitution for occupied Japan until now.She is a pro-American socialist.
Of course, that is America in 1945.She is an attorney and a symbol of Japanese deadlock  of thinking.
Her enemies are Family system and Army. "Had it not been for them, the world would be more wonderful than now"She always thinks so. To be short, she is a child.
  It is hard to realize "Free Marriage system"without destroying Family system.So,she is an anti family socialist. Japanese prime minister Hatoyama appointed her the minister of the family problem stupidly.Japanese politics seems now "the end of the world".
