Kenshin no Keishousha

Tokyo Swordia, formerly known as Tokyo Metropolitan, has been ruled by the "Swordie" since the Third World War 70 years ago. These Swordie, natural-born swordswomen with an attraction to blades, more or less rule the country, and are considered upper-class members of society.
In order to raise his own social status, Kurou, a human, begins attending an academy of swordsmanship, surrounding himself with Swordies on a daily basis. How will he fare in combat against those born to fight?
