Rebirth After the Doomsday: I, the Human Gene Bank!

The starry sky collapses. Civilization is reduced to exotic food. I am the last human being. With the genetic sequence of all human beings, go back to the day before the catastrophe. Are those in power still scheming? Are the chaebols still living in a state of intoxication? Are the Holy Mothers still calling for peaceful coexistence with alien species? It doesn't matter. I will take action.
