Where can I find this novel hidden on the shelf?

I found a novel from a long time ago, and I remembered two parts of it. One of them seemed to be about a demon who was cursed and often washed his internal organs by the river. The other was about an old demon who chose to live an ugly life. His race seemed to be all planktons. They could live for one day and absorb the miasma. When they died, they were colorful and beautiful.
