The retired Grim Reaper delivers food, the nuclear bomb code in the box, and the recipient's gun. When this order is delivered, I will let you die. The god of death on the battlefield who was sentenced to death three years ago is now anonymous, delivering food during the day, and struggling between violence and nightmares at night. On the surface, he looks taciturn and tired, but in his heart, he is a lone wolf with his head tied by a chain.
