Plot

The game is inspired by the Genpei War. Although the game features actual historical figures, their fate has been changed.

Fifteen years since the Heiji Rebellion, during which time the Heike clan reaches its height of power, Shanao, who will eventually go by the name of Yoshitsune, is dispatched to the Kurama-dera Temple without people knowing that she is female. Having learned warfare and the skills in martial arts as a girl from the Genji clan, she meets Yoritomo, Benkei, and others, until finally she challenges the Heike clan.

Characters

Main Characters

Shanaou (遮那王, Shanaō) / Minamoto no Yoshitsune (源義経, Minamoto no Yoshitsune)

The female protagonist and player character. Shanaou is her childhood name, and she later takes the name Yoshitsune. Her surname is fixed, but her first name can be changed.

The illegitimate child of Minamoto no Yoshitomo. After her father was defeated and died in the Heiji Rebellion, she was placed in the care of Kurama-dera Temple to escape the purge of the Minamoto clan. Raised as a male since childhood, she received an elite education in expectation of defeating the Taira clan, but she herself does not wish for conflict and hesitates.

Minamoto no Yoritomo (源頼朝, Minamoto no Yoritomo)

Voiced by Makoto Furukawa

The legitimate son of Minamoto no Yoshitomo and Yoshitsune's older half-brother. Having lost his father and older brother in the Heiji Rebellion during his youth, he was also sent into exile. Due to his circumstances, he harbors a sense of loneliness and is cold and ruthless, risking his life for the revival of the Minamoto clan without showing his true feelings.

Taira no Tomomori (平知盛, Taira no Tomomori)

Voiced by Jun Fukuyama

The son of Taira no Kiyomori and the commander-in-chief of the Heike army. Calm, collected, and excellent in martial arts, he is deeply trusted by Kiyomori. Contrary to his gentle appearance, he ruthlessly annihilates enemies on the battlefield. Although he grieves over the state of the Heike, he remains a bystander.

Taira no Noritsune (平教経, Taira no Noritsune)

Voiced by Kengo Kawanishi

The nephew of Taira no Kiyomori and Tomomori's cousin. Brave and fierce, he is considered the greatest warrior of the Heike, yet he is never arrogant and takes great pride as a Heike samurai. Unlike Tomomori, he does not doubt the prosperity of the Heike. He views Shanaou, who is the same age, as his arch-rival.

Musashibo Benkei (武蔵坊弁慶, Musashibō Benkei)

Voiced by Yuichiro Umehara

A warrior monk who was formerly stationed at Mount Hiei's Enryaku-ji Temple. He has a straightforward, honest personality. He was hunting swords in the capital of Kyoto against the tyrannical Heike clan, but after being defeated by Shanaou, he became her retainer and swore his loyalty.

Shungen (春玄, Shungen)

Voiced by Soma Saito

The child of Minamoto no Shigenari, a retainer of Minamoto no Yoshitomo. Because he was placed in the care of Kurama-dera Temple along with Shanaou after his father's death in battle, he knows her secret. Bright, dignified, and well-versed in military strategy, he has a feminine appearance but possesses swordsmanship skills that rival Shanaou's.

Voiced by Ryota Osaka

The son of Taira no Kiyomori and Tomomori's younger brother. A man of refined taste who excels in traditional arts such as Waka poetry, he deeply admires his blood brother.

Sato Tsugunobu (佐藤継信, Satō Tsugunobu)

Voiced by Takashi Kondo

The child of Sato Motoharu, a retainer of the Oshu Fujiwara clan. He serves Shanaou by order of Fujiwara no Hidehira, but his loyalty is overprotective to a fault. A soft-spoken individual and a samurai excellent in martial arts, he also has a calculating, dark side.

Sato Tadanobu (佐藤忠信, Satō Tadanobu)

Voiced by Katsuyuki Konishi

Tsugunobu's younger brother. Like his brother, he serves Shanaou as a samurai. The sight of him dynamically striking down enemies on the battlefield inspires his allies time and again. He has a big-hearted personality that enlivens the atmosphere, and he speaks straightforwardly to Shanaou.

Sasaki Takatsuna (佐々木高綱, Sasaki Takatsuna)

Voiced by Amatsuki

The child of Sasaki Hideyoshi, a retainer of Minamoto no Yoshitomo. He joined Yoritomo's army to overthrow the Heike and displays excellent martial prowess as a retainer to Yoritomo and Yoshitsune. With a young and honest personality, his innocent smile comforts his comrades.

Kakunichi (覚日, Kakunichi)

Voiced by Akihiro Mine

Taira no Norimori (平教盛, Taira no Norimori)

Taira no Tokuko (平徳子, Taira no Tokuko)

Voiced by Rina Sato

The daughter of Taira no Kiyomori, younger sister to Tomomori, and older sister to Shigehira. Raised with doting affection by Kiyomori, she has a free-spirited personality.
