Description: Set in the year 20XX in "NEO TOKYO," a symbol of the new era. What is the "demon summoning program" left behind by the father who disappeared? "Majin Tensei" is a simulation RPG released in 1994 for the Super Nintendo Entertainment System (SNES). The "Gaiden" that succeeded the world view of the "Majin Tensei" series, which was supported by many fans for its unique dark world view and challenging difficulty level, was "Majin Tensei: Blind Thinker," distributed on feature phones at the time. This work consists of a "story part" and a "battle part. In the "story part," the story progresses through dialogues between the protagonist, the characters surrounding him, and his opponents. When the player enters a battle, he enters the "Battle Part," and if he wins the battle, he can proceed to the next chapter. Commands include "Move," "Attack," "Magic" to heal friends and attack multiple enemies, as well as "Summon Demons," "Negotiate with Demons (Conversation)," and "Combine Demons," which are unique to the series.
