Two twins, separated by fatal illness and a selective cure. Kasumi and her sister, Shizuku, were infected with the Medusa virus, which slowly turns the victim to stone. There is no cure, but of the two only Kasumi is selected to go into a sort of cryogenically frozen state along with 159 others until a cure is found. At some point in the undetermined future, Kasumi awakens to find herself and others who were in suspended animation in an unfamiliar world with violent monsters. Resolving to unlock the mysteries of her current situation and the fate of her twin sister, Kasumi struggles to survive in a treacherous world.

"The book is better." We've all heard that idiom, and many times it's true. Marvel films are two hours at least, based on comics that have decades of celebrated, or occasionally, sordid history. Something's gonna get left out.

Enter "King of Thorn". There's an film out there, and it's good. Pretty standard modern horror anime. But KoT has six volumes that introduce a mysteriously failed world, pull us deeper into it, only to give us a psychological twist at the end that M. Night Shamylan used to be able to pull on us. Not to mention a sly exit ...

I loved this manga so much! I’m a Shingeki no Kyojin fan and this manga was right up my alley! It’s an intense psychological thriller that had me on the edge of my seat and the plot twist at the end had me shocked and wanting more. The art style matches the feeling and the atmosphere of the manga and helped make it an even more intense read. Do be warned though that there is some grotesque scenes in it so it’s not exactly for the faint of heart. I highly recommend it though, especially to any horror/thriller/psychological thriller fans!

TL;DR, not worth time investment, but short and concise enough for an afternoon binge, if you are a fan of cheap thrill and early 2000s edge.

Ibara no Ou (InO) or king of thorn, is a manga written in 2002 by Iwahara Yuji. While most people are probably familiar with him through Dimension W or character design for Darker than Black, I got to know him through Koudelka. His style can really be best described as everything good and bad about the 2000s. I love the 2000s, but there's so many things wrong with it that carried through to the modern day.

InO is about a bunch ...
