Century Paradise

If you knew the end was destined to come, how would you choose to live your life? In the second half of the 21st century after the Third World War, with only a dozen years left before the end of the century, the form and lifestyle of human society have undergone tremendous changes.

Countless elements are intertwined like intertwined light and shadow, forming the most unique paradise at the end of the century.

Gates of time and space are everywhere, science, technology and theology are advancing hand in hand... In the countdown to the impending doomsday, a group of people called "Triers" travel through time and space, looking for the last glimmer of hope. To give it a try or to survive?
