The game takes place in a fantasy world roughly modelled after medieval Europe. The starting year is given as 1210 K.D. The player's character is a famous warrior who defended the kingdom from an invasion by Lucifon, the Prince of Darkness (a corruption of Lucifer); consequently, he is known throughout the land as a military hero and receives an annual salary from the palace. One night, he receives a communication from a god whose identity is determined by the birthdate the player selects at the beginning of the game. This god bestows upon the mentioned player a child of the heavens, and it is their duty to raise her from the age of 10 to the age of 18, at which point she will enter a line of work; the most desirable outcome is that of a royal princess.
