심해수

The sea has swallowed the surface, and enormous deep-sea beasts now rule what is left of the world. Bota crosses that drowned landscape with his family, hunting for anywhere safe enough to stop while the water keeps throwing new predators at them. Stranger than any of the monsters is Kana, a girl the group takes in and cannot account for. In this Korean manhwa, every stretch of open water between one refuge and the next has to be crossed with something enormous swimming underneath.
