Today I read part of "kimi no kakera"  (pieces of you/your fragments) .  I like the premise even though the story is childish:  a country is surrounded by four tall walls and in this land snow falls continuously and eternally.  Someday the snow will bury the country completely, and the people there know it and are waiting to die.  In this setting two people cross over the walls from the high world to the low world (the lowlands below the wall encased country) to try and discover the mythical "sun" that was said to have once brought warmth to this world...Everything about it, even the title sounds cool.  "Your fragments" must be so much fun to write and draw.  I wonder, is it a story that just writes itself? 



I suppose if theres enough there (characters etc) it would be.
