Note: This is NOT shounen-ai. <br /><br />Stork, the man with no memories, and Tit, the boy with no home, travel across the grim world where the sky is grey and the birds are believed extinct. They have met accidentally and continued together, both searching. Stork searches for his past and Tit searches for a bird. They are followed by the dark mysterious man, who may have relation to Stork's past.
