"Accidental Lucky Lottery" tells a story full of love in the world. Floating back and forth between the sky and the lower world, finally one day an angel named Prapura unexpectedly appeared. Say to the protagonist that I will give you a chance to return to the lower realm and challenge again, and you must recall your criminal behavior and inject my soul into the body of a third-year elementary school student who just committed suicide and is resurrected as a real human being

But it is a pity that although Kobayashi is very good at drawing, he has no friends, and his heart is very timid. A cowardly soul who had just died and was told of serious sins, got a chance to be resurrected because of the angel's lottery activity, and entered the body of a 14-year-old boy, starting a wonderful parasitic life. With the help of the angel, his life experienced different ups and downs. From being reluctant at the beginning to experiencing the beauty and wonder of life in the end, I had a very strong relationship with my family and classmates in the end, and found the meaning of my own life and the true meaning of life.
