One of the top expert killers, tired of endless assassinations and having survived a cruel and suppressed life, decided to escape the world’s strictest assassin organization.

The humans that were brought to this world all received a totem and an egg.

Placing the totem on a certain land would turn the place into the person’s new tribe. Everyone could expand their tribes according to their strengths.
