At the beginning of each chapter, there's a humorous prologue with nude-theme.

The "Dark Flower" is a sword of legend; a horrible legend of a gruesome slaughter three hundred years past. Lilia, a small girl from a village threatened by the bandit group whose leader has obtained this cursed weapon is now searching for help to save her city. Unfortunately, she is spotted by the bandits and can only run for her life. But, just as she is about to be caught, she runs into a young and seemingly weak traveller... is this coincidence? The Winner of the 14th Square Enix Manga prize.

From Mangascreener:

The only common feature running through these stories is a grown-up protagonist somehow coming face-to-face with his childhood past, in a testament to the loss of youth, the disillusionment of growing old, and nostalgia for better times.

In the Adachi pantheon, this is a rare diametric view of his eternal theme of "youth," in this case youth as seen through the lens of the past. It's a powerful statement from Adachi that might even be an acknowledgment of his steadily-creeping age.

What is impressive about these stories is not the plots or characters themselves, but the absolutely perfect way he tells them, another facet of experience that comes with age. Most of the stories may require multiple readings to fully appreciate the airtightness of the plot and visual motifs."

From Tokyopop:

Years ago, while conducting underwater experiments, all contact with the surface was cut off.

From: Easy Going Scans

If you could find out a little something about the future, what would you do? Get rich off of the stock market? Use the media to become famous as a prophet? Or…

3, Street of Mysteries explores the fantastical-poetic vein that has forged Mizuki's reputation in Japan. The stories contained in this series hold in common the obsessive ideas of immortality and of life after death. Skillfully blending a range of black humor, drama, and questions of morality, Mizuki shows once more his profound understanding of the human soul.
