Megami Tensei Gaiden: Last Bible II (女神転生外伝 ラストバイブルII) is a Japan-only role-playing video game developed by Multimedia Intelligence Transfer and published by Atlus. The game is the second in the Megami Tensei Gaiden series. The game was originally released for the Game Boy November 19, 1993 in Japan. It was then rereleased for the Game Boy Color on April 16, 1999, much like its predecessor was.
In Magoku (マゴク, lit. Demon Country), only one baby was born one night. This is a sign that the revival of a godly power called Gryas will occur. Fifteen years later, Yuri, the main character and student of the powers of Gaia is recruited by the King of Magoku to destroy the ever approaching Gryas.
