No Game, No Life movie plot

"NO GAME NO LIFE" is a description of a pair of talented gamer brothers and sisters "Kong" and "White" who are respectfully called "Blank" on the Internet, and even considered to be urban legends. Because they were not used to the reality game called "Life", they became squatting at home and had crowd phobia. One day, they received a challenge from a boy from another world who claimed to be "God" and were summoned to another world. It was a world where war and violence were forbidden by God and everything was determined by "games". In this world, the "human race", who has been defeated repeatedly and deprived of the last piece of land, will be able to return to the glory of the past through the power of "blank".
