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.

Given the recent popularity of the horror survival genre in games and live action in the west, it’s a bit surprising that the east hasn’t shown too much keen in this rich genre, needless to say there will be some oddballs such as Iwahara Yuji who try to give it a go, and he achieved this with a few shocking results.

With a cure yet to be discovered, the disease Medusa scourges through the human race, leaving only suffering, sorrow and ultimately death in its wake. It is in such a world that Kasumi finds herself in, and with the disease already plaguing her, it’s only read more

Sooo.... I just finished this series like a few minutes ago.
It was incredibly intense~!
I loved it, even though it didn't seem like something that really fit my style. So even if you're not into the whole "what happens in the future" thing, you should at least try it ^^
It was surprising. There were some things that I totally wasn't expecting. AT ALL. But that made it so much more enjoyable :D After all, nobody likes a predicable story ne?
Also, despite it being mainly action, there were some sentimental moments. Those moments that just make you cry. (kinda... ^^;;)

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!

King of thorn is a manga where fiction, mystery and the will to survive blend in a pefect way. Each character has a story that is too hard and painful remembering it and some of them do suspicious actions that makes others feel distrust and unsteadiness.

What I like the most is the story. Even though the essence of the story is not something new (There is a pandemic disease, everyone wants to survive, there are a lot of mysteries to solves and some characters die in the way), the fiction parts is really good and unique. Also, every character has a past they don't want read more
