Rule Horror descends, humans are selected to participate in a Ghost Game. When a Chosen One dies, National Fortune collapses, and large numbers of Ghost Entities invade reality. Kael Sterling, a lifelong bachelor, becomes a Chosen One representing the Dragon Nation to enter horror instances. He starts off encountering the S-Rank Ghost instance Death Train, which has an almost 100% mortality rate. Other Chosen Ones tremble in fear before the S-Rank Female Ghost Entity, terrified that the slightest mistake will cost them their lives. Chosen One: "This is terrifying, it's an S-Rank Ghost, we're all going to die here." They turn around only to find Kael Sterling kissing and hugging the S-Rank Female Ghost Entity. Kael Sterling: "Hahaha, great, S-Rank Female Ghost, here I come." Chosen One: "We were supposed to be surviving Rule Horror, why is he flirting with the ghost?" Kael Sterling gains the Affinity System, raising Affinity Scores to conquer one stunning Female Ghost Entity after another. "Ding, congratulations, you have successfully conquered the S-Rank Female Ghost Entity, obtained an S-Rank talent." "Ding, congratulations, you have successfully conquered the SSS-Rank Female Ghost Entity, unlocked the 'Harem' achievement." "Ding, congratulations, the Female Ghost Entity has given birth to your son, unlocked new system abilities."
