Synopsis
The flood came, and it didn't stop. Now the world is submerged, the old order is gone, and sea monsters at terrifying scale own the waters that cover what used to be civilization. Bota is trying to keep his family alive in this aquatic nightmare—finding safe passage, scavenging resources, and navigating threats that operate by entirely different rules than anything the pre-flood world prepared anyone for. And somewhere in all of this, there's a girl named Kana, whose presence changes Bota's mission in ways he doesn't yet understand. Leviathan is pure survival horror manhwa—visceral, unforgiving, and built on the kind of tension that makes you afraid to turn the page and unable to stop.
