Breath of Fire IV is a role-playing video game developed by Capcom, and is the fourth game in the Breath of Fire series. It was originally released for the PlayStation in Japan and North America in 2000, and Europe in 2001. The game was later released for Windows in Europe and Japan in 2003. An enhanced PC port was released in 2025 via GOG.com.

Just as in previous games of the series, Breath of Fire IV follows the adventures of a young man named Ryu, who has the power to transform into powerful dragons. The Ryu in this game must team up with several other skilled warriors to combat an awakened immortal emperor from ascending to godhood and destroying the world of man. Like Breath of Fire III, the game utilizes a mix of two and three-dimensional computer graphics and turn-based battle sequences.

Gameplay Breath of Fire IV is a traditional role-playing video game with an overhead viewpoint. The game's camera can be manually rotated by the player up to a full 360 degrees in some instances, though unlike Breath of Fire III it cannot be tilted up or down. The game environment is rendered in full 3D, while characters are presented as two-dimensional hand-drawn sprites. While moving about the world, players can interact with computer-controlled characters and objects, gain knowledge about the world around them, and gather clues on how to advance the story. Each playable character is given a special "field skill" that can be used to destroy obstacles or solve puzzles outside of battles, which occur randomly in hostile areas or dungeons.

The "Master System" from Breath of Fire III returns, allowing players to customize each character by having them apprentice under different masters found throughout the world. Under their guidance, these characters may gain new skills and special statistic increases by fulfilling certain tasks, such as participating in a certain number of battles, or finding specific items. The fishing mini-game common to the rest of the series also returns, along with the village-building Faerie Town feature from the previous title that allows players to construct a special village that opens new features.

Battles take place with teams of three characters against any number of enemy opponents. During these combat sequences, the player can choose which characters will perform an action in any order, as well as switch in any available reserve characters from the back row. While positioned in the back row, a character may not participate in battle, but may regain lost health or magic every combat round, as well as become unaffected by any attacks. Battles end when either all enemies are defeated, or all playable characters (both the front row and reserve) are out of health. Each battle yields experience points that go toward earning levels for each character, which in turn grants increased statistics and new skills.

New to Breath of Fire IV is the Combo System, which allows certain spells or skills to be cast in a specific order to gain bonus damage or other effects. Casting two ice spells in sequence, for example, will produce a stronger ice attack, while a fire spell followed by a wind spell will create an explosion-based attack. Combos may also automatically occur in single attacks that have more than one effect.

Plot

Characters The principal characters of Breath of Fire IV were designed by series artist Tatsuya Yoshikawa, and consist of Ryu and his companions, each with their own individual skills and personality traits carry the story forward. Ryu (voiced by Kappei Yamaguchi) is an amnesic young man with the mysterious ability to transform into powerful dragons, with his "other half" being Fou-Lu (voiced by Isshin Chiba), the principal antagonist and founder of the Fou Empire centuries ago with similar abilities, yet a much more malevolent personality. Aiding Ryu on his quest to confront Fou-Lu are several other heroes including Nina (voiced by Kyoko Hikami), a winged magic-user and the reigning princess of the Kingdom of Wyndia; Cray (voiced by Isshin Chiba), a burly member of the cat-like Woren tribe who wields a large wooden post and holds romantic feelings for Nina's sister, Elina; Ershin (Master in the Japanese version, voiced by Inuko Inuyama), an enigmatic robot-like armor who speaks in third-person; Scias (voiced by Unshō Ishizuka), a lanky mercenary and swordsman from the dog-like Grassrunner clan who lives for money; and Ursula (voiced by Kumiko Watanabe), prideful granddaughter of a military commander with kitsune-like features and skilled with guns.

Primary supporting characters include Yohm, a general from the modern Fou Imperial Army with the ability to summon monsters to his aid who see Fou-Lu as a threat to the world; Rasso, an elitist company commander dispatched to the Eastern Kingdoms to search for Ryu, Fou-Lu's key to obtaining his lost godhood; Yuna, a cruel geneticist and occultist who participates in horrific acts of genetic manipulation with dark magic; and Kahn, a muscle-bound chauvinist and comic-relief villain who constantly encounters Ryu's party.

Backstory A long time ago an emperor called Muuru was having problems with the empire which was in a civil war, so he tried to summon a god named アルカイ「arukai」 (which was translated as Yorae) to unify the empire through its divinity. The summoning was imperfect, which made the god to be split both in time and bodies. The summoned god was called Fou-Lu. After ten years he was able to unify the western continent into the Fou empire. Meanwhile, the western continent was repeatedly attacked by the eastern continent, so Fou-Lu decided to create a bridge that would transport people and things to the other continent. Carrying the ambitions of Muuru, Fou-Lu wanted to unify both continents and cease the war. But due to the imperfect summoning Fou-Lu entered a sleeping state (sealed) and the empire lost its strike on the eastern continent keeping the war in a deadlock. Without Fou-lu's presence the war kept going on for many years of truces and war. Several years later, the second half of the god came into the world, waking up Fou-Lu that was sealed in a long sleep recovering his powers. And so the game begins...

Story The story of Breath of Fire IV begins with a search team consisting of Nina, princess of the Kingdom of Wyndia, and Cray, leader from the plains-dwelling Woren clan. They are heading to the town Synesta for information on the whereabouts of Nina's older sister and Cray's love interest, Elina, who went missing several weeks earlier on a diplomatic mission.Nina: It all started on the third day after we had left the castle. That morning, we had entered the Great Desert on our sandflyer. We were heading toward the town of Synesta, the last known location of my sister, Elina. They are soon attacked by a berserk dragon and their sandflier crashes, forcing Nina to go to Sarai for spare parts while Cray guards their ride. Happening upon a crater left when a strange object landed from the sky, Nina confronts a large dragon who transforms before her eyes into a young man. Remembering nothing other than his name, Ryu, Nina surmises he must have amnesia and persuades him to help her search for her sister. Meanwhile, across the world in the western Fou Empire, the ancient Emperor Fou-Lu rises from his burial tomb, declaring that it is now his time to regain his throne, as he promised over six centuries ago. He commands one of his Guardian dogs, Won-Qu, to guard the tomb before heading south. In his vulnerable, newly awakened state, he is attacked by Yohm, a general in the modern Fou army who is privy to Fou-Lu's long-prophesied resurrection, and aims to kill him before carrying out his plan.Yohm: Pardon my presumption, but I believe you are the God Emperor Fou-Lu... Yes? I have been expecting you... Ever since I saw the flames rising from the woods where I had placed my soldiers on watch. (Breath of Fire IV) Fou-Lu is overpowered in the struggle and is struck down into a ravine.

Elsewhere, Ryu and Nina run into trouble with a Fou Empire captain named Rasso and cannot get the needed spare parts in the end. While escaping the Fou soldiers, they travel to a town blighted by an evil miasma known as "hex" to get back to Cray, where they meet Ershin, a mysterious robot-like armor who leads them through the poisoned side of town.Ershin: Incorrect! Ershin is not odd. Ershin is saying she will guide these two. (Breath of Fire IV) Re-uniting with Cray, the team makes their way west to gather more information. The story shifts back to Fou-Lu, who has awakened after his ordeal with Yohm and finds himself in the care of a man named Bunyan.Bunyan: You must be wondering where you are. My name is Bunyan. I live here, in the Zhinga Mountains. I found you a few days ago, collapsed down by the river. I brought you here, and dressed your wounds. (Breath of Fire IV) After recovering enough, Fou-Lu departs down the mountain only to find Yohm and his soldiers blocking the path. After a struggle, Fou-Lu is forced to flee by transforming into a dragon and flying away, declaring that he must find his "other half", Ryu, and re-unite with him before the Empire finds him first. Yohm summons another creature to chase and strike Fou-Lu down. It succeeds and Fou-Lu crashes into the forest below.

By this time, Ryu and his friends arrive at the border town of Kyojin, where they meet Captain Rasso again who attempts to block them from entering the Causeway's gates. Quickly escaping past the guards in Fou Empire's continent, the team make their way north where they meet Yuna, an Imperial scientist who knows of Elina. He claims that she was here but is no longer. The soldiers then capture and return them to the Eastern Lands with accusations of breaking the pre-war peace treaty by trespassing in their lands. The group is detained in the town of Ludia and Cray is set to stand trial on their behalf. The group tries to help by "lessening the evidence" against Cray but to no effect with the judge. With no other choice Ryu, Nina and Ershin break him out of captivity with the help of Scias, a tall, dog-like mercenary who joins their cause. Determined to clear their names and find Elina, they travel past a swamp and through a volcano to arrive in Wyndia, where after an audience with Nina's father, the king, the group continues west. After seeking the Wind Dragon at the top of an ancient temple and brought to an ancient summoners' village, the group learns of Ryu's heritage, why the Empire is after Ryu, and the danger he would be in should he and Fou-Lu ever meet. They also learn that Ershin is carrying an Endless' spirit named Deis. While the group learns all this, Captain Rasso tracks Ryu to the summoners' village and kills most of the villagers. They then meet Ursula, granddaughter of a high-ranking Fou Empire official, who is against Rasso's savage methods. After attacking the villagers, Captain Rasso pulls out his trump card against Ryu. Ryu goes berserk and incinerates all the soldiers and Rasso and almost kills Ursula too, but Nina manages to calm Ryu down. Before leaving for Kyojin again along the western border, Ursula joins the group to keep an eye on them. Learning that the Causeway broke down after their initial visit, they find that they need a ship in order to proceed with their journey.
