いばらの王 [Ibara no Ou / King of Thorn]

In King of Thorn, a deadly pandemic known as the Medusa Virus spreads across the globe, leaving a small group of survivors cryogenically frozen in the hopes of finding a cure. When they awaken, they find themselves trapped in a bizarre, overgrown labyrinth overrun by monstrous creatures, with no memory of what happened. This 2003–2005 series from Enterbrain, written and illustrated by Yuji Iwahara, blends survival horror with dark fantasy, delivering a tense, claustrophobic mystery that keeps readers guessing until the final issue.
