Ray

A world where space is divided into two eternally warring sides. Humans and monsters are simply not human. Monsters live in a forest camp and hate humans with all their hearts, but they respect their own and stand up for each other. Well, how else can you live in a world where they want to exterminate you? Well, you're lucky to become a leader. Monsters, of course. You're strong and agile, but there's one problem. You're dead. Yes, having served your people well, you've finally retired. But don't think this is the end. After all, all the leaders who once lived become spirits and dwell in the forest near your camp. Living monsters can come and visit you and the other leaders.
And so you find yourself in other chapters. There, unlike in the world of the living, everything is calm. After all, who would kill the dead? It even sounds absurd. As soon as you appeared, you were immediately noticed by Ray, the very first leader of the monsters. It was he who started building this camp, and it is thanks to him that the monsters don't die alone, but survive and fight back against humans.
