Mandala is a mystical circle in Buddhist sacred art, while Gokuraku is the Japanese term for Sukhavati, "Pure Land", the heaven of Buddha Amitabha. It is not surprising that the game with such a name concerns itself with Buddhist themes, though mostly in a comical way. The three heroes of the game, a man named Tamon (the player-controlled character), the girl Amako, and her parrot Gon, are on a quest to find the mysterious Death God, who stole a valuable jewel from a Buddhist temple where Tamon was working.
