About two hundred years ago, the king who tried to conquer the continent and even the world, with his demonic subordinates, continued to attack the city, even the city under the temple was not spared, but here, Brad, Mary and Gus led their partners to fight against this group of demons. In the end, the king was fought by Brad, Mary and Gus, and sealed under the city, facing the demons outside, and this seal was only a delay. However, in the face of the immortal god who can also swing the sword, the undead god also dislikes it, so at the moment when the king is sealed, on the pretext of helping to destroy the demons under the king outside, he forces the three to sign a contract and become the undead to join his camp, so that they can protect the seal.
The goal of the immortal god is to turn all the good souls into immortality and create a world of stagnation and no sorrow.
The three undead sent away (born old and sick and died) all the companions of the king before they died, but the male protagonist was sent to the ruined city by a group of demons as a tribute to lift the seal of the king. Brad and Mary's kind nature prompts them to be unable to see the male protagonist and not save him, but will fully raise the male protagonist and cultivate adults. With the passage of time, the accumulation of emotions, the companionship of love, to the moment when the male protagonist becomes an adult, Brad and Mary, who play the parents, will eventually lose their attachment to guarding the seal of the king, then it is time to honor the contract, and the immortal god will take away the souls of the three people and be bound by them forever, which is an intolerable thing for Gus as a friend.
From the adoption and teaching of the male protagonist, Gus has always opposed it, because he knows that the day when the souls of the two friends are harvested by the immortal god will eventually come, and because of the existence of the male protagonist, it will come earlier, more unpredictable, difficult courses, old-fashioned and serious attitudes, representing his dissatisfaction and worry about his friends, but through the male protagonist has a partial regret memory of the previous life, almost genius-like understanding and the image of a well-behaved child who studies hard, growing up more rapidly, Brad and Mary put all their minds on the male protagonist, in order to avoid the premature occurrence of tragedy, even if the entanglement and struggle, Gus still made the decision to kill the male protagonist in the dungeon, so he intervened in the male protagonist's first dungeon training, and finally looked at the male protagonist's tears, gave up the appearance of struggle, and finally personally broke the decision to kill the male protagonist, but this reason was not known until the last male protagonist, all because of the existence of the undead god.
