Hel Tilos is a prince of the Kasyapa planet who is about to come of age. The ancestors of the Kasyapa people are called the descendants of the gods. They have a star rule. Every adult Kasyapa must pass the test of thirteen lessons before they can hold the coming-of-age ceremony, and Hel is no exception.
Hull's trial site was chosen on a planet called Earth.
His Royal Highness, the perfect prince who has been doing decathlon since childhood and has perfect scores in Keke, finds this not difficult at all.
But after arriving on Earth, he first encountered a major problem - hunger.
That is, the people of Kasyapa live by eating souls, but the humans here are not willing to sacrifice their souls after achieving their wishes.
Facing people on earth with different professions and identities and backgrounds, Hull began his thirteen lessons.
Mission: Protecting the Earth is everyone's responsibility
