There will always be a kind of person who lives on excitement and lives a wanton and unrestrained life. They make fun of the world, but they each have their own unique talents. They are doing things that may cost them their lives at any time, but they each have a net worth of over 100 million. During the day, they have different identities that are equally envied and pursued, but in this night, they are unknown killers.
There is always an organization that takes in such people
Night Stalkers - that's the organization
A killer spent his life subverting the entire organization because of a mistake he made when he was young. But he forever lost his body as a killer. With the connections he accumulated over the years and his extraordinary abilities, he established Night Demon, allowing a group of young people to continue their hearts and futures. . . .
