YUU KAMIYA's Manga List

Naoto is a brilliant amateur mechanic who spends his days tinkering with gears and inventions. And the world is a playground - a massive, intricate machine. But his quiet life is disrupted when a box containing an automaton in the shape of a girl crashes into his home. Could this be an omen of a breakdown in Naoto's delicate clockwork planet? And is this his chance to become a hero?

A world governed entirely by games does not favor a timid, powerless race like Immanity, but it's perfect for a pair of legendary shut-in gamers! Sora and Shiro are now king and queen of Elkia, the last bastion of Immanity. But saving a kingdom is no small task, and responsibility isn't a game either sibling claims to have a high score in... Good thing the allure of more challenging contests (and sexy animal women) is all the motivation they need to set their sights on a new conquest-Immanity's powerful neighbor, the Eastern Union!

In a world where everything is decided by games, adorable (but foulmouthed) Izuna Hatsuse is a young Werebeast girl who wants to learn more. As she follows Sora, Shiro, and the others, what answers will she find for herself? LET THE GAMES BEGIN!

The original light novel that started the phenomenon!

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...!

YOU NEVER KNOW WHAT'S IN THE CARDS... Before the creation of Disboard, a world where everything is decided by games, there raged a terrible war among the various races. The Immanity weren't the only ones fighting to end that war, though-one Elf had her own plans: Whoever's left standing after the world is destroyed is the winner! What tricks did Think Nirvalen have up her sleeve all those years ago? Who was actually pulling the strings behind the Great War? And did Nina Clive, Think's overworked assistant, even make it out alive?!
