A picture book based on a traditional Japanese story that tells the adventures of a fisherman, fantastically fused with the story of the Sea King. The originality of the book derives from having two different stories with the same illustrations. Furthermore, this is a bilingual book, here in a Spanish/Japanese version. This picture book was awarded the "Monstruo" prize by the Zaragoza School of Art for the best project presented by students from all Art & Design courses in the academic year 2010-11.
