Ayashimon is a Japanese manga about a young man named Maruo who dreams of becoming a strong manga protagonist like the heroes he admires. He has superhuman strength but no direction until he meets Urara, a girl from a hidden world of yokai (mythical Japanese spirits). Urara wants to overthrow the violent yakuza-like gangs that rule the yokai underworld, and she recruits Maruo as her bodyguard and enforcer. Together, they dive into a world of gang warfare, supernatural battles, and secret societies. Readers enjoy the series for its fast-paced action, the contrast between Maruo's simple heroism and the complex yokai politics, and the vibrant, chaotic world inspired by Japanese folklore and crime dramas.
