Megami Tensei Gaiden: Last Bible, localized as Revelations: The Demon Slayer, is the first of four games in the Last Bible series.


"Long before human beings existed... Telepathy, Teleportation, Telekinesis... Power that only Gods could harness. Gods named this power Gaia. This is the beginning of tragedy..."
Revelations: The Demon Slayer Introduction

The Last Bible series is set in a fantasy world patterned after the ancient Middle East. In this world, humans have learned to call upon the energy of the world, called Gaia. The hero, El, has studied Gaia, but on the day of his graduation, strange creatures begin to appear. Together with his companions, he sets out to defeat the Gaia Masters that are bringing monsters to their world.


  • El (エル) - The protagonist who begins a journey from the town of Moila to investigate the appearance of monsters. He has the ability to contract demons. Through his journey, he gains the power of the Force.
  • Kishe (キシュ) - A young man from Remlia that El helps to find medicine for. After being healed, he offers to join El's party. Kishe is capable of performing demon fusion.
  • Uranus (ウラノス) - Rafael's daughter, and El's second party member once she's rescued from the Nest of Zord. She learns powerful healing spells.
  • Zodia (ゾディア) - El's teacher who is defeated early on at Mt. Palo while trying to save the residents there and leaves to search for greater Gaia powers. He created the Zord in search of new power and has to be defeated by El's party.
  • Rafael (ラファエル) - The priest of Ramuh. He travels to the Tower of Magan to reclaim an orb stolen by the Gaia Masters. He is killed by them.
  • Mephist (メフィスト) - One of the three Gaia Masters and the first El confronts.
  • Vaerial (ベリアル) - The second Gaia Master that El has to fight.
  • Baal (バアル) - The third Gaia Master that El faces in Luciferium.
  • Lucifer (ルシフェル) - The final Gaia Master and final boss.

Game GearEdit

The Game Gear version of the game features new sprites for the game's monsters and characters and completely different ending with exclusive last location and boss; these changes are exclusive to the Game Gear version, and were not carried over into the colorized version that appeared on the Game Boy Color and the 3DS Virtual Console. 


In the localization process, a few sprites were switched in order to conform to western rating systems, in particular altering the appearance of some main characters. Dave Augusta made a patch to revert these changes in the game that can be found here.
