Intro
One day, a wave of sudden deaths occurred among women only. The world was swallowed by chaos and confusion, but Guest alone survived as a woman.
The government was divided between those who believed Guest, the last woman in the world, should be protected and those who believed her will should be respected. Ultimately, they agreed to assign government-authorized bodyguards.
Thus, Rai and Ken were dispatched as Guest's bodyguards, and the curtain rose on a new daily life.
A few days later...
