Description
Jisai Kanemaki is a tall, well-built man with long hair tied back and a scar on the left side of his face. He wears a light-colored kimono and carries a sword secured with chains at his side. Having lost his right leg, he moves with the aid of a walking stick. His physical appearance is strongly mirrored in his son, Kojiro Kanemaki.

Fifteen years before the main events, Jisai served in the Uesugi Bushi Band. He gained significant recognition for exterminating a Kishin, earning the title of "hero." While his fame fell short of the "Five Grand Generals," he won admiration from many Bushi, especially within the Hojo Bushi Band. Following this period of renown, Jisai vanished from public life in Hinomoto, leading many to assume his death.

This disappearance was required by his role as the "Obsidian Goddess's Sheath," compelling him to hide in a Kishin-controlled rural village. His duty centered on protecting Musashi, identified as the "Vessel of the Obsidian Goddess." During this time in hiding, Jisai fathered his son Kojiro Kanemaki, who is roughly the same age as Musashi. Jisai raised both boys together, training them in swordsmanship to become formidable Bushi.

Jisai maintains a kind and calm demeanor, enduring persistent hostility and harsh treatment from villagers due to his Bushi heritage. He shows deep love and concern for his son’s well-being. Jisai takes pride in his ancestral lineage and consistently encourages Kojiro to embrace his identity as a descendant of Bushi warriors.

His commitment to protecting Kojiro and Musashi leads to his sacrifice. When the "Obsidian Eight" discover their location, Jisai acts to save the boys. He is subjected to the brutal "cow tearing punishment," resulting in his body being ripped apart. This traumatic event profoundly affects Kojiro and Musashi. While Musashi remains steadfast in his ambition to become a Bushi, witnessing his father figure’s death causes Kojiro to develop deep doubts about the Bushi’s existence and the validity of Jisai’s teachings.

Jisai’s legacy endures through his influence on Kojiro and Musashi. He trained them in swordsmanship and instilled core values of Bushi pride and responsibility. His teachings and sacrifice fundamentally shape their paths and motivations. His character draws inspiration from the historical swordsman Kanemaki Jisai, master of Sasaki Kojirō.
