"God's Hand with a Crown" is an adventure game set in a fantasy world called "Gradonera". The story begins when the main character, Rehat (renamed), who lives in the Kingdom of Ritant, learns the secret of his birth through the death of his mother.

Lehat, who lived quietly in a remote village with his mother, lost his mother at the age of 14. Lehat's forehead had something like a bruise by nature, but he had kept it hidden for a long time at the behest of his mother. Lehat himself thought it was only a "strange bruise", but in reality, this bruise was the "selection mark of Anekius", the succession to the throne of the Kingdom of Retanto. Shortly after his mother died and he couldn't hide his bruises, a man named "Ronica" appeared under Lehat, calling himself the messenger of the royal castle. Rehat, who received an explanation from him about the "Selection Mark of Anekius," is forcibly taken to the royal castle.
