This is post-apocalyptic pastoral at its finest. Also, gothic, action-adventure, and several other genres.
The world has drowned in nothingness, but some scant few shreds of the old cosmos remain, largely having forgotten themselves. The gods and devils and Knights of Nothingness of old live on as schoolboys and shopkeepers and mad scientists, moving through mad miraculous tales in the stable remnants of the universe. Will you unravel the mystery of who slew the sun and plunged the universe into oblivion? Resurrect and re-start the world that was? Or just appreciate a slow, sunny day by the shores of Big Lake with your friends?
Chuubo is a game of many stories starring a roster of "pre-generated" characters, who are more like customizable character classes or archetypes than standard pre-gens. (Someone plays The Best Friend, for example, but there's enormous latitude to make that character concept your own, including modding name, gender, personality, etc-- only his 'mythic archetype' and associated powers are kind of fixed.) There's really nothing else on the market quite like it. Rules are diceless and very easy to use, and the art and layout are gorgeous and charming.
