Between Two Souls (English)

Mother Earth is healing herself. In the 20th and 21st centuries, the World is engulfed in two major wars between mankind. Survivors migrated massively to war-free places, but the impact was still felt there. Bacteria, viruses, radiation, and mutated creatures continue to erode the human population.

But humans continue to develop science in search of new planets. A group of scientists discovered a planet similar to the Earth called Valkan. Hoping to communicate, they created a tool called SOULS that can connect the soul of its users to distant places.

Adrien Adrestia, a prince of the Kingdom of Arestiana gets the "Grace" of connecting with the earthlings. However, it turns out that he is connected to a serial killer inmate coded Zero. An ideological battle took place in his head. Not only that, the threat of war from enemy kingdoms and earth colonies continues to heat up. Will Adrien and Zero try to stop that? Or are they fighting for bodies?
