Grim is the human incarnation of the Grim Reaper. While delivering food, Grim was deliberately harassed by a customer, resulting in a heart attack and death. However, he unexpectedly awakened to his identity and skills as the Grim Reaper. First, he went to the hospital to revive his mother, then exposed his girlfriend Sophia's scheme. Emma, the president of the Tracy family, passed by and witnessed Grim's magic, pleading with Grim to go to the auction to treat her grandfather Nathaniel, where he coincidentally encountered Sophia and her lover Marcus. Initially, everyone constantly mocked and questioned Grim's identity and abilities, but Grim kept using his power as the Grim Reaper to prove them wrong and capture the evil spirits who had escaped from the underworld. In the end, he eliminated all obstacles, saved Nathaniel, and got together with Emma.
