Description
Himeko Murata is a prominent character known for her role as a teacher and squad leader within the world of Honkai Impact 3rd, and her portrayal in Cooking With Valkyries brings these established traits into a lighter, slice-of-life setting. She is the captain of the Hyperion and an instructor at St. Freya Academy, where she leads the Fifth Squad, which includes cadets Kiana Kaslana, Mei Raiden, and Bronya Zaychik.

Her background is one of significant personal sacrifice and loss. Initially an academically gifted student who earned a doctorate from the California Institute of Technology, Himeko originally aspired to follow in her father's footsteps as a scientist. However, after the tragedy of the Honkai impacted her life and led to the death of her father, she abandoned her dream of exploring the stars. Seeking the truth about his death, she accepted an invitation from Theresa Apocalypse and joined the valkyrie forces at St. Freya Academy. Unlike many valkyries, Himeko does not possess a natural resistance to Honkai energy. To compensate, she received artificial stigmata developed by Schicksal, which allowed her to wear combat suits but came at the great cost of drastically shortening her lifespan.

In terms of personality, Himeko presents a complex mix of professionalism and personal flaws. She is a dedicated and willful fighter who takes her role as a protector very seriously, often acting recklessly in battle when the lives of others are at stake. Despite her skill and leadership as a captain, she has a notoriously relaxed attitude toward paperwork and a well-documented struggle with alcoholism, sometimes even drinking while teaching. This lazy and disorganized side contrasts with her disciplined combat demeanor. She is also notably sensitive about her lack of romantic success, a point of irritation she sometimes drowns in alcohol. Beneath these surface flaws, she harbors a deeply caring and motherly nature, particularly toward her students, whom she views as family.

Her primary motivation throughout her story is a strong sense of duty and care for those under her protection. After being nearly the sole survivor of a mission that wiped out her assault squad under the tutelage of her friend and mentor, Ragna, Himeko chose to become a teacher to guide the next generation. This is most evident in her relationship with Kiana Kaslana. Despite knowing Kiana's status as a clone, Himeko consistently sees her as a person and goes to great lengths to protect her, ultimately sacrificing her own chance at survival to save Kiana from the Herrscher of the Void by injecting her with a God-Slaying Spear.

Within the story, her role evolves from a frontline valkyrie and captain to a mentor and, ultimately, a tragic hero. Key relationships shape her path. She shares a close bond with Theresa Apocalypse, who recruited her and cares for her despite her shortened life expectancy. Her relationship with her students Kiana, Mei, and Bronya is central, as she acts as their protector and teacher, often going against higher authority to keep them safe. Her development is marked by a journey from a promising scientist to a hardened soldier, and finally to a selfless teacher who finds purpose not in her original dreams, but in ensuring her students have a future.

In Cooking With Valkyries, the focus shifts to her everyday life at St. Freya Academy, highlighting her lighter, more domestic side. Within this setting, her established role as a mentor and guardian to Kiana, Mei, and Bronya remains intact, but it is explored through shared activities like cooking and eating together, revealing the more relaxed and familial aspects of her character outside of combat. This series emphasizes her personality traits in a low-stakes environment, showing her interactions with her squad away from the battlefield while still carrying the warmth and care that defines her as their captain.

Her notable abilities include being a skilled combatant who wields a two-handed greatsword, a style she learned from her mentor Ragna. As a valkyrie, she can equip the Nexus battlesuit and later the Vermillion Knight armor. While her artificial stigmata provide her with the power to fight, they are also a constant reminder of her physical fragility and her shortened time. Her most defining moment of capability is not just her physical strength, but her incredible willpower, demonstrated when she fought against a Herrscher and made the ultimate sacrifice to save her student from a fate worse than death.
