MTL - Seizing a Good Marriage, The Virtuous Medical Consort - ~ End: Destroy the world, continue three life

Lucas was the last human in the universe.A cosmic-scale war had consumed humanity in massive destruction. As collateral damage, there were no longer any habitable planets. Lucas Alhamera, a scientist, attempted to terraform a planet resembling Earth called Antroseda but continuously failed.Overwhelmed by despair and the crushing weight of loneliness, Lucas attempted to end his own life using a euthanasia capsule. However, just before his life could be taken, he was abruptly awakened by a notification.[As the last of the dominant species, you have been chosen as the new Overseer of this universe.][The cycle of life must continue to preserve balance.][Select planet as the birthplace of the new species (default)][Select another planet...]With the Overseer System he had obtained, Lucas began what he had failed to do for hundreds of years: reviving a dead planet and creating a new race to succeed humanity.

The previous lords have committed as many atrocities as possible to fill their bellies. I, the only daughter of that house, had discovered that my servant and lover was a spy.

And as the people wanted, my life ended with my execution.

However, with the memory of getting beheaded intact, I began a new life. I was planning to shoulder the sins of my past life and become a nun, but by some trick of fate, I came to work as a maid for the current lord.

Under my former lover, whose name, age and even hair colour were all lies.

The aliens came with hostility.
Facing the invasion of aliens, human beings are weak like ants.
So this is the end, the real end.
But there is resistance when there is an invasion.
For some, this is not the end, it is war.
So this is war.
Real war!
