Meet Sama, a 10-year-old boy who is so sad that tears have literally stained his cheeks. Sama's father has had a heart attack, and doctors give him a month to live. With his teddy bear in tow, Sama crawls under his bed and finds a magical portal to a strange realm called Undertown. What is this dark new world? To find out, Sama begins a journey through the depths of Undertown, where he searches for The Sugar Stone, a magical object that might be able to save his dad! This is volume 1 of the Undertown manga series.
Humanity trembles before the Grenimals, grotesque creatures born from corrupted desire. Among them roam the Lycanthropes, savage beasts driven by their lust for chaos and pleasure, and the Vampires, who see humans as nothing more than cattle to be bled dry.
As the world teeters on the brink of madness, those who hunt what should not exist, the Executioners, rise to stand against the encroaching darkness.
Among their ranks are Mutuki, a stoic, battle-hardened warrior, and his sharp-witted partner Yuri, as they plunge into one supernatural mystery after another, each case more twisted than the last, each unveiling horrors festering in the shadows of their crumbling world.
A dark action fantasy of mystery, survival, and vengeance begins, where the line between hunter and hunted begin to blur.
