The Cruel World... Wars, constantly erupting everywhere, had become a routine affair. In such a world, the status of an ordinary person did not distinguish you from livestock, which anyone stronger could kill, violate, or enslave. What truly held value in this world was strength!

A boy named Kai had lived in a small orphanage since birth. Often, he had to sneak into the village to steal a bit of food. This way, he could save at least a small amount of sustenance for his family.

A series of events forces Kai to leave his sanctuary and venture into the outside world. At a critical moment, he discovers the enigmatic Sphere, or perhaps the Sphere discovers him...

P.s. No harem, no romance, no weak main character.
