 Adam Cleveland at IGN called Revelations: The Demon Slayer a fun but not innovative game. The American game magazine Nintendo Power did however find it innovative; for instance, they cited the automatic battle option. Cleveland disliked the monster conversation system, which he found irritating; he said that players never know what answer they should give a monster, and that the questions the monsters ask feel monotone due to how often they are repeated. Writers for the Japanese game magazine Famitsu thought the monster fusion system was fun. In their review of Last Bible III, they commented on how different the game is from the Megami Tensei series, and instead compared it to Final Fantasy. Kurt Kalata and Christopher J. Snelgrove wrote for Hardcore Gaming 101 that while The Demon Slayer was not by any means an outstanding game, it was one of few competent role-playing games on Game Boy. They found Last Bible III to be the best game in the series.
