I Swear an Oath to the Goddess

After Brunei saved the world, he signed a contract with the goddess to continue saving this devastated magical world without killing anyone. Due to the power of the contract, Brunei will be punished by the gods whenever he uses force. In the face of injustice, Brunei can only stop its activities. Gradually, he changed from a hero to a dog that everyone yelled at, suffering humiliation and torture. Only then did he realize that the injustice in the human world was caused intentionally by the divine world.
