Story

The year is 2020, in the megacity of Seoul. Invasions of dimensional monster have destroyed Seoul, but were soon pushed back. Seoul was rebuilt, and this is a story of CLOSERS in New Seoul. Mysterious dimensional gates opens all over the planet, and unleashed a worldwide invasion of monsters. No weapons or tactics had any effect on the waves of dimensional monsters pouring out of the dimensional gates. Cities upon cities were mercilessly destroyed.

But the opening of the dimensional gates did not only cause damage and destruction. The psychokinetic power that awoke also enabled a small 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. After unspeakable losses, the people of earth at last 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, people returned to the world, and cities were rebuilt. Through dedicated research into the dimensional gates and psychokinetic powers, 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.

But soon the dimensional gates all over the world started shaking again, and even stronger outbreed creatures began their attack on earth!

The story of CLOSERS begins with high school students who are members of the Black Lambs, the UNION squad active in New Seoul. Their duty is clear!

Put on the uniform of a Black Lamb, and become a CLOSER to protect New Seoul from the invaders!
