For Kurahashi, figuring out the mystery of the Petit Cossette that appears to him in his waking dreams is a matter of life or death... and his sanity...
Both Petit Cossette and the Soultaker are directed and mostly thought up by Akiyuki Shinbo, and it shows.

The storyline in Petit Cossette is very similar to the Soultaker as well, almost as it were a miniaturized version of the story, but with enough differences in it's gothic style to keep it fresh and entertaining.
