Transmigration: To become the greatest of villain

2055
A time of turbulence and uncertainty.
With the sudden arrival of the dungeons, in the form of space rifts, a new era of awakeners began.
In this world, where more and more dimensions are connected, as time flies by, a man is reborn.
Only noticing the world to be very similar to a game he played. A harem-building game that is.
