Lucas and ren

The year is 2036. Ten years ago, a mysterious virus called Vix spread across the world. The virus killed nearly every man, leaving humanity with an overwhelmingly female population. Before the outbreak reached him, Ren Draven was placed into experimental cold sleep, preserving his body until a cure could be developed. Ten years later, Ren awakens at age 25 to a world he barely recognizes. He soon discovers that another man survived: Lucas, an arrogant and self-confident survivor. With the male population nearly gone, governments establish a voluntary population-recovery program, and Ren and Lucas become extremely important to humanity's future. Ren's secretary, Akari, helps organize candidates for the program, while Lucas's secretary, Sofia, handles Lucas's selections. Ren's beautiful sister, Miyuki Draven, is also among the survivors.
