“Platinum Award. Tezuka blends high-adventure plotting with deep and thoughtful themes in his inimitable style... It seems a shame it's only all been in Japanese until now.”

“Sleek in design and swift in pacing, the story's blend of mayhem and laffs and depression creates a uniquely chaotic world… The monster designs are excellent, ranging from detailed etchings to gargantuan masses of doomy scribbles.”
“Simply put, Vertical’s English translation of Osamu Tezuka’s late '60s swords-and-goblins saga is a work of such genius that one must term it not only inspired but also inspiring—it's a reminder of why one reads manga in the first place. Exquisitely rendered and mind-bogglingly creative.”
“By far Tezuka’s edgiest work at that point in his career, this series is riveting and, frankly, creepy as hell, with Tezuka’s signature ‘cute’ style offering a welcome counterpoint to the visceral horrors depicted.
“The premise and Tezuka's eerie renditions of larval Hyakkimaru and the monsters that come after him is unusually effective and chilling.”
