The Shigeru Mizuki Complete Manga Collection is a significant find for enthusiasts of Japanese manga, particularly given Mizuki's profound influence on the supernatural genre and yokai folklore through works like "GeGeGe no Kitaro." This complete set, showcasing unpublished sketches and drafts, not only highlights the artist's creative process but also represents a rarity in the collector's market, as many of Mizuki's themes resonate deeply within Japanese culture and artistic expression.

Collectors value the authenticity of Japan-sourced items, which ensures superior quality control, packaging integrity, and prints not commonly available outside Japan.

As out-of-print editions, the condition of these volumes plays a crucial role in their collectability, making this set a noteworthy investment.
