In a fictional country that was once threatened by low birth rates and an aging population, a law was passed to enforce marriage at the age of 18. Failure to comply results in the death penalty — if you don’t get married by the day of high school graduation where marriage ceremonies are held nationwide, you are taken to the Bachelor Jail and executed. Kekkon Shugi Kokka is a collection of 8 short stories surrounding 16 teenagers who live under this law, in a country where “love” and “romance” are glorified to the point of brainwashing and marriage is a matter of life and death.
