King of Thorn is a Japanese fantastique manga series written and illustrated by Yuji Iwahara. It was published by Enterbrain in the seinen magazine Monthly Comic Beam between October 2002 and October 2005 and collected in six bound volumes. It is licensed in North America by Tokyopop, with the final volume published in November 2008. The series is about a group of people who are put in suspended animation to escape a mysterious plague that turns people to stone, and upon waking there appears to be only seven survivors in a world run wild—including a Japanese teenage girl named Kasumi Ishiki and a British man named Marco Owen. The survivors soon discover that the entire ruin is filled with strange, dinosaur-like creatures and other monstrous aberrations of nature. Thinking that a great amount of time passed since their arrival on the island, soon the survivors discover not only that their sleep was indeed too short to label such dramatic changes as natural occurrence, but also that the situation in and of itself is far greater than they could imagine.
