When the Brown Eyed Girls each receive prophecies of a hellish  kingdom and army that they are tasked to rule, you know chaos is bound to erupt. With their eyes set on pleasing the devil by forming armies and armies of the demonic dead and beasts, world domination seemed to be just as their grasp. They come up with a plan called the Sixth Sense which called for the forced branding of all people in order to believe in them and worship them as their lords. All those who refuse to condone their newfound religion are subjected to torture. Many people, out of fear, start to worship them but those who are brave stay strong and do not bow down to their vileness. Those who do not believe are sent to prisons, forests, and torture chambers where they are forced to suffer and killed. It was like World War II over again only on a different scale. 

Our heroes, Operation Tree hear about this and team up once more under the guidance of TREE Headquarters, Onew, and Hyunah. This time, they are aided by two other agents who choose to stand up and fight for their loved ones who are detained under the rule of the Sixth Sense. One is adoptee Nichkhun who lost his adoptive parents in the hands of the treacherous Secret Society, a subordinate cult of the Sixth Sense regime, and rebel Minho who after having his family massacred one night by Secret Society members, has become and activist to stand up against the reign of the Brown Eyed Girls. These 7 people are brought together by TREE Headquarters and since all are fighting for a single cause, they are united and tasked to put an end to this demonic reign.

The Brown Eyed Girls receive another prophecy from their demon lords that they must kill 50 al young women in order for their Sixth Sense domination to be complete. With already 45 lobbied in for death, it seemed as though they had already killed enough people for them. Just then, the Brown Eyed Girls see in their Luciferian Orb, the omnicious orb that they use to see how their progress is, and see Operation TREE about to hunt them down. Knowing that they have almost outnumbered the army, Narsha orders the Secret Society to kidnap them and bring them before her and her sisters. Along with the two boys, the 5 girls are seperated and detained in a more horrible place while the boys are forced to do labour in order to build their kingdom. Nichkhun, who has developed an attraction to Sohee, tries to find a way out of their chamber along with Minho. The girls, however are skilled enough to escape on their own and just when they are all free, they get back on their feet and kick some .

The third and final installment of the OPERATION TREE story series. It's been good writing these. I love this story and I'm glad that you liked it, too.
