Once again, the Game Master's world of quests unexpectedly pulls in Yuusuke Yotsuya and the rest of this old team. Accompanied by the newest addition, Keita Torii, the team reunites with Kahabell, still unaware of their actions' impact on this world. After bidding Kahabell farewell, the team sets out on their newly appointed quest—an offering of a Jiffon Buffalo at Vaikdamnia on Jiffon Island. However, as their journey to the island commences, the team shortly finds that the quest is not as simple as it initially seemed. In fact, the island is terrorized by orcs that have made a deal with its inhabitants: instead of devouring the islanders, the orcs will be granted buffalo. With the growing shortage of buffalo, the annual Vaikdamnia festival cannot proceed. But, given the importance of the team's quest, they are left with the obvious choice—rid the island of the orcs and save the islanders. [Written by MAL Rewrite]

After the invading dimensional monsters were beaten back, Seoul was rebuilt. This is the story of Closers in New Seoul. Mysterious dimensional gates opened all over the planet and unleashed a worldwide invasion of dimensional monsters. No monsters and tactics had any effect on the waves of dimensional monsters pouring out of the dimensional gates. City after city was mercilessly destroyed. But the opening of the dimensional gates did not only cause damage and destruction. The psychokinetic power that it awoke also enabled a tiny minority of humans to gain extraordinary psychic powers. With these psychic warriors, governments around the world were able to turn the tide of the war with these monsters. After unspeakable losses, the people of earth at least succeeded in closing the gates. Since they had closed the gates, these psychics began to be called "CLOSERS," and the invasion of the dimensional monsters was named the First Dimensional War. With the dimensional monsters vanquished, peace returned to the world, and the cities were rebuilt. Through dedicated research into the dimensional gates and psychokinetic power, humans learned that the gates open when there is a singularity in this mysterious power. However, their understanding of the gates was still incomplete. The CLOSERS who survived the First Dimensional War became part of an organization called UNION. Together, they researched the psychokinetic power in all over the world, working to prevent another dimensional war. And that's when the dimensional gates all over the world started shaking again - as ever stronger outbreed creatures renewed the attack on earth. (Source: Wikipedia)
