Grim!

Lucius is an arrogant grim reaper. He was sent to reap a girl's soul, who was supposed to die from a brain damage. Lucius then appeared before the girl, Elena, thinking it would be an easy job to take a sickly human soul. However, it turns out that Elena was perfectly fine and healthy! Failed to reap Elena's soul, Lucius was expelled to the human world as a punishment.
