He is a traveler of the night. He has no home, no name, and no fear. His only destination is the weak.
Every night he walks through the dark, looking for people who are lost. People with empty hearts, people who need something to believe in. He finds them, and he stands in their doorway with a book in one hand and a blade in the other.
He never breaks in. He never forces anyone. He just talks.
Slowly, he fills their minds with his belief. He tells them they are chosen, that their pain has a meaning, that giving up their souls is the only way to be free. And they listen. They believe him. Little by little, they become slaves to his ideology.
By the time the sun rises, there is nothing left to fight. His victims give him their souls willingly, with a smile on their faces.
The blade is only the end of the story. The real killing happens in the mind.
He is the Shadow Passenger Killer. He doesn't take your life. He makes you hand it over.
