It's a wacky worldview based on magic and weapons. First of all, people in this worldview may stop growing older at any time as soon as they are born, and maintain it forever. Not dead, except in war. The era when I was born happened to be a time of melee. Unfortunately, I stopped growing in age before I reached adulthood. Is this opening the door to hell? Or a new twists and turns in life? In this world where humans, gods, ghosts and demons coexist. Where is my life going?
