Taira no Masakado was a samurai during the Heian period in Japan. He led a small but thriving rebellion to capture three provinces - Hitachi, Shimotsuke and Kouzuke - now known as the Kanto region's Ibaraki, Tochigi and Gunma prefectures respectively. As a response to the rebellious member of the Taira clan, the Kyoto central government at the time announced the bounty on his head. At the Battle of Kojima occurring eastward of Kanto, Masakado was killed by Fujiwara no Hidesato and Taira no Sadamori, his cousin. His head was brought to Kyoto, and later to Edo where it was buried. Here he is regarded by the locals as a demigod, and a belief persists that the conditions of his shrine dictates the fortune of the metropolis.
After the great flood, the player can visit the dwelling place of Masakado on a solitary island, if they are following the Neutral path. He laments the destruction of Tokyo between the warring factions, and bestows his sword to the player.
Masakado is first mentioned upon Aleph's arrival to Roppongi, where he is greeted by a servant, Hiruko. According to Hiruko, the general's body is currently torn to six-pieces as he fell victim to the internal conflict between the Yamato Gods. Thus, Hiruko requests Aleph to break the seals sealing the six pieces of the corpse, and retrieve them so Masakado can be resurrected.
Upon retrieving all of the body pieces, Hiruko will then prompt Aleph to fuse them all and resurrect him at the Jakyo Manor. However, as Aleph only retrieved Masakado's corpse, but not his soul, the fusion of the body parts creates the soulless form of Masakado. Hiruko later informs Aleph that the general's soul is crucial to fully resurrect him, and reveals that he actually holds it. Congratulating Aleph for his efforts in retrieving Masakado's body parts, Hiruko grants the soul to Aleph, allowing the fusion master to fuse Masakado's soul to his body, fully resurrecting him.
As a token of gratitude for resurrecting him, Masakado grants Aleph the Sun Pillar and Katana of Masakado, and helps Aleph to break the lock in the Sealed Cave. There, Aleph must then free the Amatsukami clan sealed inside. Masakado later informs Aleph that due to his recent awakening, his powers are not fully healed yet, and thus needs rest for to recover his strength, bidding him farewell.
In the Neutral route, Katana of Masakado later helps Aleph in banishing the guard demons guarding Lucifer's Castle Kether.
Masakado makes a cameo appearance in Shin Megami Tensei III: Nocturne. If the Demi-fiend manages to collect all of the 24 Magatama scattered around the Vortex World, the minister of the Cathedral of Shadows will give the Demi-fiend the "Lord's Blade", advising him to visit the grave of Masakado with the sword in his possession. Upon examining the gravestone, the blade will react, and the Demi-fiend will find himself teleported to the Bandou Shrine.
After lowering the pillars and defeating all four Devas, the Demi-fiend can finally approach Masakado, who proceeds to question the Demi-fiend's purpose. Regardless of the answer, Masakado will impart his power to the Demi-fiend in the form of the Magatama Masakados. It is all he can do since he cannot exist in the world outside.
Masakado also tells the Demi-fiend that regardless of what kind of world Tokyo would turn out to be, it is still Tokyo. As the current bearer of his power, the Demi-fiend will now protect Tokyo in Masakado's stead however the Demi-fiend sees fit. If the player re-enters and speaks to Masakado again, the general will encourage the Demi-fiend to journey forth and conquer the multiverse and further prompts him to choose how he best feels Tokyo should be protected.
"A general who declared himself the new emperor of Japan, but fell to Hidesato Fujiwara and Sadamori Taira. He was enshrined to quell his spirit, and later became known as the protector god of Kanto. According to the Otogizoshi, he was over 210 cm tall, had a body made of metal, and had two pupils in his left eye. However, he had a weakness: his temple was still made of flesh."

Masakado is a key figure in the story and is central to the Neutral route. His sword is carried by Skins, who cannot unsheathe it. On Neutral Skins will pass down the sword to the player when the latter speaks Masakado's name and is able to unsheathe the sword. Masakado became the ceiling over Tokyo to prevent God's wrath from destroying the city, and whatever little of his power remained after creating the Firmament was sealed away in Ginza. By drawing the sword in front of the monolith there, Masakado's soul is awakened once again. Masakado greets Flynn by name, noting that he has been reincarnated.
In the neutral route Masakado attempts to remove the Firmament above Tokyo, but is unable to do so without the Three Great Spirits of Hope, Goodwill, and Spite which grant him power since most of his own is still in the ceiling. Flynn is tasked with retrieving them: the Great Spirit of Hope must be recreated by giving hope to the people of Tokyo by becoming Champion and is initially the only one needed until Masakado learned the other two had become the Demon Lord and God's Chariot.
The Great Spirit of Goodwill became Merkabah and the Great Spirit of Spite became Lucifer, both of whom seek to become the hopes of the people and now go against the spirit of Hope which they both are supposed to support. Upon collecting Goodwill, Isabeau evacuates the Eastern Kingdom of Mikado to allow Masakado to remove the Firmament. Once Spite has been obtained both are fed to the deity, he fuses with the Firmament and returns to his true form, destroying Mikado and returning the sky and sunlight to Tokyo.
"The body double of Taira no Masakado, which appears in the Otogizoshi. It is said there were seven doubles, or perhaps seven total with the real one included. This number comes from Myoken worship. In the Otogizoshi, the doubles were created from straw dolls, but there are legends which say the doubles were vassals who sacrificed themselves for their lord."

In the "For the Past... For the Future" DLC Challenge Quest, it is revealed by Stephen that Flynn's former self accompanied Masakado to defend Tokyo from the ICBM attack 25 years ago. Masakado took the form of a gigantic being to become the shield, but by doing so he went berserk and threatened to destroy Tokyo. Flynn was sent back in time to help control the raging god, but had no choice but to attack Masakado until he came to his senses.
The grueling battle was timed, as time grew short as the missile approached Tokyo, leaving only ten turns to defeat Masakado. After his defeat, he moans about how he lost control of the good and evil within him, and only Flynn's hopes have restored his true self. He promises to protect Tokyo and Flynn's hope as his body then steadily falls down and covers the entirety of Tokyo, becoming the Firmament. His back was later used by the angels to construct what would become the Eastern Kingdom of Mikado.
Masakado communicates a final time with Flynn, telling him humanity has been protected, but still must endure good and evil in the eternal battle of law against chaos, and thanks him for giving all humans the gift of hope, saying that as long as there is hope, the Goddess shall never die. He then grants Flynn his Shadow's data, allowing him to summon it as a demon in battle.
