After teleporting away, Chisato appeared in the Mega world of Nadier, the land of death. And she had came here to meet the leader and the Overlord of this place.
Nadier was something extremely important for this whole universe. Other than being just one of the five mega worlds, it was also the sole region in charge of death and reincarnation of this universe.
The universe where Elena and Chisato were born, there each and every one of the world had a individual cycle of reincarnation and a separate realm for the dead to rest. But that was not the case here.
There was only a single cycle of reincarnation and it was handled by the ruler of Nadier and his subordinates. This had immediately made this place extremely important even among the mega worlds.
The ruler of this world and one of the 7 rank 11 powerhouses of this universe was called the Death Overlord. He was also the being who was in charge of the whole reincarnation process.
