Final Fantasy IV, a role-playing video game released by Square in 1991, revolves around Cecil Harvey, a knight of Baron who embarks on a quest to defeat Golbez, a man that is controlling the king of Baron. During Cecil's quest, he is joined by his childhood friends Kain Highwind and Rosa Farrell, as well as other warriors from around the world who also seek to stop Golbez. The visuals of the characters were designed by Yoshitaka Amano. After its initial release, Final Fantasy IV was later ported to multiple consoles. In 2007, Square Enix released an enhanced remake for the Nintendo DS that added voice acting to both the Japanese and English versions.

Final Fantasy IV, titled Final Fantasy II in its initial North American release, is a role-playing video game developed and published by Square for the Super Nintendo Entertainment System. Released in 1991, it is the fourth main installment of the Final Fantasy series. The game's story follows Cecil, a dark knight, as he tries to prevent the sorcerer Golbez from seizing powerful crystals and destroying the world. He is joined on this quest by a frequently changing group of allies. Final Fantasy IV introduced innovations that became staples of the Final Fantasy series and role-playing games in general. Its "Active Time Battle" system was used in five subsequent Final Fantasy games, and unlike prior games in the series, IV gave each character their own unchangeable character class — although at a few points in the story, a dark knight will choose the path of a paladin, or a summoner will evolve to a new tier of spellcasting.
