The previous ruler of Imanity, as well as Steph's grandfather. His reign led to many losses for Imanity, thus many people call him a, "Foolish King." 

He is terrible at games, being unable to win a majority. However, he is able to give Imanity a chance by finding out opponent's secrets. When he was near the end of his life, he entrusted Steph with, "The Key to Imanity's Hope;" which is to be given to someone who is capable of saving Imanity.

Bored with life and considering the real world to be just a “crappy game,” savvy sibling shut-ins Sora and Shiro have withdrawn into their own fantasy world filled with video games. 
 
However, one day they find themselves summoned to another world by a boy who calls himself “God,” their abilities are about to be put to the ultimate test! Now not only their fates — but the fate of all of humanity — will be decided by a series of games that may just be the hardest these super-geniuses have ever faced!

In this fantasy world, everything's a game--and these gamer siblings play to win! Meet Sora and Shiro, a brother and sister who are loser shut-ins by normal standards. But these siblings don't play by the rules of the "crappy game" that is average society. In the world of gaming, this genius pair reigns supreme, their invincible avatar so famous that it's the stuff of urban legend. So when a young boy calling himself God summons the siblings to a fantastic alternate world where war is forbidden and all conflicts--even those involving national borders--are decided by the outcome of games, Sora and Shiro have pretty much hit the jackpot. But they soon learn that in this world, humanity, cornered and outnumbered by other species, survives within the confines of one city. Will Sora and Shiro, two failures at life, turn out to be the saviors of mankind? Let the games begin...!
