in the city of lights are soldiers who protect the weaker people, many years ago a war started between humans and vampires and Tanjiro was one of the soldiers and he was actually supposed to kill vampires...

They're invited onto a boat for an experiment. But there's a dark truth behind the survival classes. They don't realize how much they've lost and just how little is left. Now they only have each other, or do they? When the experiment on the mainland goes horribly wrong they have only very little options. They try their hardest to stay alive but only God knows if they'll make it or not. What'll happen when they realize that nothing can be fixed? They're stuck at sea, but what can you do when there's nothing to go back to? They're one of the only boats left in the sea, the boat of humanity. #1 muitan (April 10, 2022)
