Characters

Main Characters

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.

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.

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.

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.

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.

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.

Secondary Characters

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. On the other hand, he has a side that seeks fleeting pleasures, acting cruelly on the battlefield and becoming intoxicated by the combat rather than the victory or defeat.

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.

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.

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.

A disciple of Ajari Rennin of Kurama-dera's Toko-bo. He raised Shanaou and Shungen, who were left at the temple immediately after birth, as temple youths, teaching them martial arts and military strategy, and fostering their aspirations to revive the Minamoto clan.

A wealthy merchant who sells gold mined in Oshu in Kyoto. Traveling through various provinces, he is well-versed in the movements of the world. He wishes to welcome Shanaou to Hiraizumi.

The leader of the Taira clan. A figure who rose to power after his active roles in the Hogen and Heiji Rebellions. His influence is immense, and he reigns at the apex of society while maintaining a cooperative relationship with the cloistered government.

Noritsune's father and Taira no Kiyomori's younger half-brother. He calmly accepts the prosperity of the Heike and is a person capable of voicing opinions on Kiyomori's actions.

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. By entering the court as Emperor Takakura's consort and giving birth to an heir, she solidified the position of the Heike clan.

The third head of the Oshu Fujiwara clan. A man of character who rules over the vast region of Oshu, where the power of the Heike does not reach, and cares deeply about his clan. He also watches over Shanaou's future with concern.

A military commander descended from the Kamakura clan of Sagami Province. A tactician whose thoughts are difficult to read. He moved from the Taira side to become Yoritomo's close confidant, and also serves as Shanaou's supervisor.

The son of Minamoto no Yoshikata, also known as Kiso Yoshinaka. Although he behaves in a rough manner, his swordsmanship skills are certain, and his majestic presence earns him the popularity and trust of others.
