Description
Freesia Yagyu, biological daughter of the legendary swordsman Yagyu Jubei and the Siberian woman Trusia, was born in Japan's feudal era. Her family relocated to Siberia after Jubei was dispatched to confront Kita Retsusai, leader of the Northern Yagyu clan. Jubei refused to train her in swordsmanship, wishing her a life free from the sword's burden, though he recognized her natural talent when she displayed early skill using twigs as practice blades. During the climactic duel between her father and Kita Retsusai on a frozen river, the ice shattered. This event caused the drowning deaths of her mother and Kita Retsusai, while Freesia became trapped in suspended animation within the glacial ice.

Preserved for approximately 300 years, she was released during the modern era due to glacial melting from global warming. Awakening in Hokkaido, she was initially raised by forest animals who taught her survival skills and provided companionship. Learning from these animal caretakers that her parents died centuries earlier and that her father's legacy—the "Lovely Eyepatch" containing his swordsmanship techniques—had been entrusted to an unrelated successor named Jiyu Nanohana, Freesia experienced profound betrayal and resentment. Believing the eyepatch was her rightful inheritance as Jubei's direct descendant, she crafted her own "Spade Eyepatch" to channel a version of her father's power and embarked on a quest to reclaim the Lovely Eyepatch from Jiyu.

To facilitate her goals, Freesia integrated herself into Jiyu's life by transferring to her school, feigning friendship, and manipulating Jiyu's father, Sai Nanohana, into allowing her to live with them. This proximity enabled her dual identity: outwardly presenting as a cheerful, hyperactive, and socially charming transfer student while secretly plotting against Jiyu. Her cheerful demeanor masked intense envy and a ruthless determination to inflict emotional suffering rather than seek Jiyu's death. This included psychologically tormenting Jiyu, such as manipulating Sai into slapping his daughter by falsely claiming Jiyu had rejected him as her father.

Her swordsmanship skills, derived from her lineage and enhanced by the Spade Eyepatch, were characterized by lethal precision and visceral aggression, described as fundamentally different in spirit from her father's techniques. Despite her combat prowess, defeating Jiyu failed to bring her satisfaction. Her focus shifted toward confronting the Siberian Yagyu clan (formerly the Northern Yagyu), whom she held responsible for her father's fate. This pursuit culminated in a crisis during a rematch with Jiyu, where Freesia—frustrated by her inability to achieve victory—pleaded for greater power from her father's spirit. Instead, she received a revelation: her father's true wish was for her to live free from the sword's influence, and her Spade Eyepatch was a legitimate manifestation of his legacy, not an inferior imitation.

This realization prompted a transformative understanding that both she and Jiyu were genuine successors to Yagyu Jubei's legacy. Freesia tearfully apologized to Jiyu, reconciling their rivalry. In the final battle against the spectral manifestation of Kita Retsusai, she fused with Jiyu, combining their strengths to summon the original Yagyu Jubei's spirit and defeat the entity. Following this conflict, her father's spirit entrusted her to Sai Nanohana's care. The epilogue depicts her beginning a new life as an ordinary schoolgirl, no longer driven by vengeance or the pursuit of the Lovely Eyepatch.

Her abilities include masterful swordsmanship with or without her eyepatch, superhuman physical strength demonstrated even in childhood, fluency in Russian from her Siberian upbringing, and the capacity to communicate with animals—a skill developed during her time with the forest creatures after her awakening.
