Minamoto no Yoshitsune (源 義経) was a general of the Minamoto clan during the late Heian and early Kamakura period. Yoshitsune was born in 1159 during the Heiji Rebellion, which claimed the lives of his father and brothers. He was put under the care of Kurama Temple. Eventually, Yoshitsune wound up under the wing of Fujiwara no Hidehira, the head of the Fujiwara clan. He was a skilled swordsman, as he defeated the legendary Benkei in a duel, who served under Yoshitsune after his loss. Yoshitsune eventually wound up participating in the conflict known as the Genpei War, that saw his clan versus the Taira clan and the victory of the first, where he slew his rival Minamoto no Yoshinaka. Yoshitsune then served the emperor until he was forced to flee back to Fujiwara for protection. He was betrayed and forced to commit suicide along with his wife and daughter by Hidehira's son. Minamoto no Yoshitsune has been popular in Japanese culture due to his appearance as the main character in parts of Heike Monogatari. The term Hangan-biiki (sympathy for a tragic hero) stems from the title of Hangan, which Yoshitsune received from the imperial court.
Yoshitsune was a central figure in the 2013 Summer event where players could obtain and upgrade variants of him named after different landmarks in his life. The final variant in this chain was Hassotobi Yoshitsune, which learned the signature spin move Hassotobi. He returned as a minor NPC as the object of Moh Shuuvu's affections in the 2014 Valentine's event and as player support in the White Day event. His plug-in and non-variant form were added during the seventh anniversary event, where players could fuse him in a special double-fusion of Tokisada and Daisoujou.
He was added as a permanent obtainable plugin with the implementation of Mount Kurama, along with the weaker variants from the initial event.

Like most members of the Famed race, he can only be obtained through a fusion accident. His armor, Genke Rindo, divided in Helmet, Chest and Legwear, is available for sale at the secret shop in Ginza. It is one of the highest-level sets of armor in the game, reflecting Gun attacks and nulling Light and Dark at the cost of a weakness to Wind-type attacks.
Shin Megami Tensei IV Apocalypse
As in the previous game, Famed race demons like Yoshitsune can primairly only be obtained through fusion accidents, however certain Famed race demons can also be obtained from the "A Godslayer Needs Demons" DLC and though meeting specific requirements with Fusion-type DDS.

"A Japanese general of the Genpei War near the end of the Heian era and start of the Kamakura era. Also known as Ushiwakamaru, he is said to have learned the art of war from the Mt. Kurama Tengu. On joining his half-brother Yoritomo's army, he defeated the Taira one by one, finishing them off at the battle of Dan-no-Ura. Later, he was pursued by Yoritomo's army and killed himself at Koromogawa."

Devil Summoner: Raidou Kuzunoha vs. The Soulless Army
Yoshitsune appears as a secret demon in Raidou vs. The Soulless Army. He can only be summoned after he is defeated in the 4th floor in Training Hall. Yoshitsune can be summoned once Raidou reaches Lv. 37 or above.
Persona 4
Yoshitsune appears as a Persona of the Tower Arcana in Persona 4. He is available to be summoned once the protagonist reaches Lv. 75 or above. Yoshitsune's fusion prerequisite requires the protagonist to perform a Pentagon Fusion spread that consists of Hachiman, Masakado, Okuninushi, Hitokotonushi and Shiki-Ouji in the Velvet Room. He cannot be fused before July 10th, as Pentagon Fusion would not be unlocked by then.
Yoshitsune bears the distinction of being one of the two player Personas that have access to the most potent status-buff skill, Heat Riser (Trumpeter being the other one). Furthermore, he learns the strongest area-based, multi-hit type Physical based attack, Hassou Tobi.
Also, Yoshitsune is the only Persona with two dedicated Fusion Forecast enhancement schedules to give him new skills when he is created on specific dates. December 19th will grant him the Arms Master skill (this skill is also inheritable from Masakado), while December 24th will give him the unique skill Debilitate.
