Species: Human
Birthplace: Bonaparte
Birthdate: 402 IE
Royal House: Yamato, grandniece of King Yanuhito
Princess Consort Mitsuko, aka Commander Mitsuko Windsor, née Yamato, is the royal chief of security to King Edward Windsor of Bonaparte, a reservist in the Compact Navy Special Forces, and a decorated combat officer with longstanding ties to the Children of Amargosa. Trained by the Household Guards, she is known for her sharp instincts, formidable field leadership, and complete refusal to be defined by her aristocratic background.
Early Career and Liberation Campaign
Deployed to Hanar in 429 IE during Compact–Gelt cooperation efforts, Mitsuko was tasked with assessing Gelt Warrior candidates for integration into Compact Special Forces. There, she met JT Austin and began training him in close-quarters combat and tactical operations—skills he would later use in the Liberation of Amargosa.
Her wartime camaraderie with Suicide evolved quickly into mutual respect, while her bond with fellow officer Giddeus Modesto deepened into an intense but unresolved romance. She became a grounding presence for JT Austin and Connor Duffy, treating them like younger brothers amid the chaos of occupation.
Mitsuko’s gunship was shot down during the clean fusion blast that destroyed Riverside, but she survived and continued to play a crucial role through the Liberation’s end.
Post-Liberation Operations and Political Turning Point
In the aftermath of the war, Mitsuko resumed field operations with the Navy, including a high-risk diplomatic mission to Kaku V, where rogue settlers had provoked conflict with a native cephalopod species. It was during this operation—recounted in The Cephalopods—that she received a proposal of marriage from Edward Windsor, then heir to Bonaparte’s throne. Mitsuko responded with conditional acceptance: she would not give up her rank, career, or independence.
During the events of Checkmate, Mitsuko and Edward remained engaged but unmarried. She served aboard the Valles Marineris and helped plan the countermeasures against emerging radical Cubist activity, particularly as it intersected with rogue Dasarius tech.
Raid on Aphrodite and Final Battle with Kurz
In 434 IE, Mitsuko was deployed to Aphrodite to confront Gerard Kurz, a radical Cubist and former Dasarius operative who had hijacked ancient terraforming mechs to attack Ares. Leading a joint team with Suicide, Davra Andraste, and others, Mitsuko spearheaded the raid on Kurz’s jungle encampment.
She was captured during the retreat, held in a corrupted Cubist shrine, and surgically mutilated—her wrist chip removed to erase her identity. She escaped with the aid of Patchi and Keernith, only to learn they planned to sell her to Jez Salamacis. Upon her rescue by Compact forces, she invoked Section 11 and executed Takeshi Sakimoto for treason and military abuse.
Final Assault on Mt. Buxanshal:
Mitsuko led the concluding assault on Gerard Kurz’s last stronghold atop Mt. Buxanshal, a cult-consecrated site housing a submerged nuclear device. While her team—Suicide, JT Austin, Davra Andraste, Ellie Nardino, and others—executed a frontal assault to draw away Kurz’s defenders, Mitsuko free-climbed the rear slope of the mountain and infiltrated the crater lake alone. There, she located and disabled the fission bomb’s detonator. Kurz attacked her mid-operation, forcing a brutal hand-to-hand fight in the flooded chamber. She ultimately used his body as a shield against the detonator’s secondary explosion. The blast killed Kurz and partially collapsed the chamber. Mitsuko survived with severe injuries, including fractured ribs and a broken jaw, and was later evacuated to the Valles Marineris for treatment.
Recovery and Acceptance of Royal Role
During her slow recovery at the reclaimed Cubist retreat, Mitsuko spent time with Suicide and Master Ansel, reflecting on the spiritual consequences of war, radicalism, and distorted faith. With JT Austin and Tishla among her visitors, she gradually healed and prepared to return to Bonaparte.
Status as Princess Consort:
After her return, Mitsuko formally married Edward Windsor in a private ceremony aboard a royal helium airship. She explicitly refused the title of queen, stating, “The Queen’s job is to get pregnant if she’s not the monarch. I’ve got better things to do.” Instead, she took the title Princess Consort Mitsuko Windsor and insisted on remaining a commissioned officer in the Navy and royal chief of security. She resumed a role blending tactical command, intelligence oversight, and personal protection of the royal family.
Hosh Assignment and Covert Ops
Shortly after her wedding, Mitsuko returned to the field in Another Way to Die. Alongside Eric Yuwono, she became involved in an investigation into surviving elements of Juno on Hosh, a non-aligned Class-E world. Though no longer in an active combat role, Mitsuko coordinated off-books efforts by Cybercommand, maintaining her dual identity as royal and operative.
Her involvement in the Hosh operation highlighted her adaptability: equal parts diplomat, bodyguard, and strategist. Despite being newly married, she resisted calls to retreat into palace life, stating privately to Davra Andraste and others that being royalty “doesn’t mean I have to become useless.”
Overturning the Hanar Coup and Expansion of the Foundation
In Suicide Gambit, Mitsuko Yamato enters the conflict as Bonaparte’s emissary to Hanar, tasked with offering formal union between the two post-Compact powers. She links up with JT, Suicide, and Tishla at Armaneya, immediately slotting into the team with the ease of someone who has walked through fire with them before. Though technically there as a diplomat, Mitsuko operates as a tactician, intelligence officer, and emotional ballast—particularly for JT, who is spiraling from exhaustion, grief, and the rekindling of his bond with Tishla. With her usual blunt humor and no-nonsense presence, Mitsuko joins Suicide and Tishla in quietly conspiring to keep JT from pushing himself too far. She never lectures or protests; she just makes sure he eats, rests, and doesn’t do anything suicidal unless it’s strictly mission-critical.
When the Sovereign arrives on Hanar and deems the immediate marriage of JT and Tishla politically essential, Mitsuko not only attends the wedding but revels in the absurdity of the moment. The ceremony, conducted in traditional Marilynist fashion, requires nudity—something Mitsuko fully embraces. She insists on being photographed with the newlyweds, joking that the pictures should first be sent to her husband Edward and then posted to social media because, “I haven’t had a really good scandal since becoming princess consort.” Beneath the dry wit and public irreverence, however, Mitsuko’s support is unwavering. She knows exactly what this union means—for Tishla’s legitimacy, for JT’s peace of mind, and for the future of the fragile postwar alliances they’re all struggling to maintain. In Suicide Gambit, Mitsuko proves again that she’s far more than a soldier or noblewoman—she’s the glue binding fractured loyalties together, whether through strategy, friendship, or strategic scandal.
Raid on Liberty
In Breaking Liberty, Mitsuko Yamato temporarily sheds her royal obligations to join Suicide’s mission to the sovereign citizen world of Liberty. She arrives with a team to help extract Tishla from Jez Salamacis and remains in the field through the subsequent escape aboard the Hadrian. When enemy mechs breach the ship, Mitsuko stands ready at the airlock while Ellie and Suicide engage them in vacuum. Later, she joins Davra Andraste’s boarding party to confront two mechs that made it inside, handling herself with characteristic precision—and just enough disdain to remind everyone she was still a princess, just one with a pulse rifle.
Legacy and Outlook
The Kaku V mission marked a pivotal shift in Mitsuko’s journey:
-
She asserted independence from House Yamato
-
She maintained close ties with the Children of Amargosa, particularly JT and Ellie Nardino
-
She began questioning whether her future lay in courtly service—or the freedom and purpose she found fighting alongside rebels and refugees
Though still a princess by blood, Mitsuko Yamato is far more defined by her battlefield experience and unshakable code than her lineage.
Relationships:
Suicide: Suicide became both a mentor and surrogate older sister to Mitsuko Yamato after the Liberation of Amargosa. Their bond, rooted in shared battlefield experience and blunt honesty, helped Mitsuko rebuild her life after the war and resist the suffocating expectations of Bonaparte’s royal court.
While Mitsuko often projected cool authority, it was Suicide who encouraged her to remain emotionally authentic, even irreverent—particularly when palace life demanded the opposite. It was Suicide who first told her, with a wry grin, that Mitsuko wasn’t just a soldier or a princess, but the “older sister” to the Children of Amargosa.
Their relationship remains one of deep trust, quiet loyalty, and tactical alignment, even as their roles diverge. When Mitsuko thwarts an assassination attempt on Edward, the two fight side by side once more—tracking down Gerard Kurz, confronting the radicalization of Cubist ideology, and ultimately surviving the war on Aphrodite. After Kurz’s death, Suicide remains with Mitsuko during her recovery, reaffirming their bond not just as comrades, but as chosen family.
In Suicide Gambit, Mitsuko and Suicide operate in perfect tandem—rarely needing to speak aloud to coordinate their actions. Their mutual respect deepens as they work to stabilize JT and support Tishla’s restoration. While their personalities remain distinct—Mitsuko the sharp-edged aristocrat-saboteur, Suicide the hardened idealist turned pragmatist—they’ve clearly become strategic partners and kindred spirits. Mitsuko never questions Suicide’s leadership, even in the most chaotic moments, and Suicide, in turn, trusts Mitsuko with the kind of unspoken authority usually reserved for JT. In quieter moments, they share dry commentary, war-worn glances, and a fierce protectiveness over the next generation of rebels and rulers they’ve helped shape.
Giddeus Modesto: Giddeus Modesto was Mitsuko’s romantic partner during the Amargosa occupation and liberation. Their relationship was rooted in mutual trust and shared battlefield experience. Giddeus’s death during the final phase of the liberation devastated Mitsuko, leaving a lasting impact on her views about attachment, duty, and future commitments. Even as she rebuilt her life among the Amargosan resistance circle, his memory continued to shape her decisions.
JT Austin: Mitsuko and JT Austin share a bond forged in war and tempered by trust. What began as battlefield camaraderie during the Occupation of Amargosa matured into a surrogate sibling dynamic—one rooted in blunt honesty, deep loyalty, and mutual reliance. Mitsuko treats JT as chosen family, often trusting his instincts more than those of her fellow officers or royal advisors. For his part, JT considers Mitsuko his best friend—the person most likely to get him drunk just to force out what’s bothering him.
Their connection deepens aboard the Queen Maria Sophia, where JT helps Mitsuko navigate the loss of her great-uncle, King Yanuhito, and the pressures of her impending role in Bonaparte’s monarchy. Though their relationship is never romantic, it is intensely personal, marked by emotional candor few others can draw from either of them.
Later, as JT struggles to recover from a crash during a freight run, it is Mitsuko who bluntly—yet compassionately—urges him to reconcile with Suicide. Her directness pushes him to act just before Ellie Nardino ropes him into the rescue mission, showing once again how Mitsuko knows not just what JT needs to hear, but when and how to say it.
Her quieter gestures also speak volumes—such as asking to buy JT’s cabin on Amargosa as a place to escape the suffocating demands of royal life. It’s a personal nod to their shared past, a reminder that even as she becomes Princess Consort, JT remains one of the few people allowed to talk to her like she’s still just “Mitsuko.” For a time, he’s the only one who can call her “Mitzy.”
In Hosh operation, despite being newly married and managing royal security, she makes sure JT is included in the operation to Hosh—trusting no one else to balance the covert mission’s chaos with the same level of loyalty, improvisation, and brutal honesty they’ve always shared.
Mitsuko’s bond with JT in Suicide Gambit is that of a battlefield sibling—intimate, unshakeable, and free of pretense. She knows him better than almost anyone and wastes no time pretending he’s fine when he clearly isn’t. At Armaneya, she joins Suicide and Tishla in subtly managing his self-destructive instincts, alternating between strategic support and blunt sarcasm to keep him functional. When his marriage to Tishla becomes an immediate political necessity, she offers no hesitation, only loyalty—attending the nude Marilynist ceremony with gleeful irreverence and posing for photos she jokingly threatens to send to Edward and post to social media. Beneath the teasing, however, Mitsuko sees JT’s exhaustion, devotion, and sacrifice—and treats them with the gravity they deserve. By the end of the operation, her role in his life is firmly cemented: not just trainer, not just friend, but a protective big sister who’ll always have his six, even if she has to do it naked in front of royalty.
Connor Duffy: Mitsuko formed a strong but slightly more protective bond with Connor Duffy during and after the Amargosa occupation. She saw Duffy’s mechanical skills and sharp mind as vital assets, but also recognized his underlying vulnerability beneath the sarcasm. Like JT, Duffy became part of the surrogate family Mitsuko found among the resistance survivors, with Mitsuko often treating him like a younger brother she needed to look out for.
Ellie Nardino: Mitsuko quickly bonded with Ellie Nardino during the Liberation of Amargosa, forming a dynamic that blended camaraderie with protective sisterhood. While Mitsuko respected Ellie’s razor-sharp instincts, loyalty, and tactical brilliance, she never forgot that Ellie was still a teenager through much of their time together—an age at which survival shouldn’t have been required training.
Mitsuko often treated Ellie like a mischievous younger sister, offering both blunt advice and quietly fierce support. Ellie, in turn, gave Mitsuko an anchor beyond the rigidity of military life and royal protocol—someone who laughed in the face of danger and still managed to be emotionally present.
Their friendship only deepened after the Liberation, as both women became part of the tight-knit surrogate family that helped guide Ellie’s path into adulthood. Whether sharing drinks after missions or standing watch during crisis, Mitsuko became one of the few people Ellie consistently relied on—and one of the few whose approval she truly cared about.
Edward Windsor: Mitsuko and Edward Windsor share a complex bond shaped by shared battlefield experience, mutual respect, and the looming weight of royal expectation. Edward proposed to Mitsuko during the Kaku V mission, recognizing in her a rare partner who understood both the demands of Special Forces and the burdens of monarchy. Mitsuko, while fond of Edward and respectful of his dedication, made it clear from the beginning that she would not abandon her autonomy—setting firm conditions around marriage, her military service, and her role in the future court.
During her time on the Queen Maria Sophia, their relationship is tested when Edward is recalled home to take the throne after the apparent death of King Yanuhito. The couple reconciles during the mission to extract Edward, and Mitsuko stands by him as he assumes his duties. However, they soon learn that Yanuhito is not dead—he has instead undergone Thulian rejuvenation, an Orag-influenced Bonapartan custom practiced by retiring monarchs. Mitsuko and Edward undergo the same procedure, discovering that Queen Widow Reiko is also participating. This moment reframes their succession as a deliberate and culturally rooted rite of passage, one Edward himself will eventually repeat. Mitsuko accepts her role alongside him—but reaffirms that she will continue serving, refusing to become a purely ceremonial consort.
When intelligence placed Mitsuko in mortal danger on Aphrodite, Edward defied protocol and dispatched an entire Compact Navy starship to support her, assigning full Household Guard deployment despite the political risk. Though barred from combat, he remained involved at every step, making clear that her survival mattered more than appearances. His decision ultimately ensured her extraction—and cemented the Compact’s resolve against Kurz.
Their wedding, held in New Tokyo with both Windsor and Yamato traditions represented, marked the culmination of their personal and political journey. Mitsuko became Princess Consort, not Queen—a title she rejected with characteristic bluntness:
“The Queen’s job is to get pregnant if she’s not the monarch. I’ve got better things to do.”
Even at her wedding, she wore a sidearm beneath her formal gown, and Edward wouldn’t have had it any other way.
Lattus Tishla: While Mitsuko and Tishla interact less often than either does with JT Austin or the other Children of Amargosa, there’s a shared understanding between them grounded in mutual respect. Mitsuko recognizes Tishla as a powerful, stabilizing force in JT’s life—and is arguably the loudest voice telling him he’s an idiot for not pursuing a deeper relationship with her. She’s frank about it, often pointing out what Tishla brings out in him that no one else can.
Despite their limited direct time together, Mitsuko’s attitude toward Tishla is free of jealousy or rivalry. She sees the first citizen of Hanar as someone who challenges JT to grow, and whom she would likely get along with—if the universe would ever give them time to sit down and talk.
At Mitsuko and Edward Windsor’s wedding reception, that opportunity finally comes—when Tishla playfully pulls Mitsuko into a dance, surprising many of the royal guests. With a teasing smile, Tishla declares, “You’re my first human woman.” Mitsuko, ever the straight-faced soldier, simply replies, “You’re not bad for a concubine-turned-head-of-state.” The moment breaks the ice, sparking laughter—and marking the beginning of a unique friendship rooted in honesty, strength, and shared affection for a very complicated man.
In Suicide Gambit, Mitsuko’s relationship with Tishla evolves from respectful distance to active alliance. Though not close before the events of the Hanar coup, Mitsuko quickly recognizes the weight Tishla carries—both as a leader and as the one person who can steady JT when even Suicide can’t. She offers political backing on behalf of Bonaparte, but more importantly, she provides quiet, unwavering support as Tishla prepares to reclaim her world. Mitsuko never questions Tishla’s right to rule or her bond with JT; instead, she reinforces it, even offering dry advice on how to manage her “idiot pilot.” When Tishla asks Ellie and Mitsuko to stand with her during the impromptu wedding, Mitsuko agrees without flinching—treating the ceremony as both a solemn duty and a moment to inject levity into a heavy situation. By the end, a clear if unspoken respect forms between them—two women from different worlds, united by war, politics, and the shared task of holding one man (and occasionally an entire peace process) together.
Susan Areestes: Mitsuko first took notice of Susan Areestes during the events of The Cephalopods, where Areestes served as part of the Compact’s forward response team on Kaku V**. In a tense hostage rescue involving a sapient aquatic species, Areestes displayed calm under pressure, precision tactics, and a sharp sense of initiative. Mitsuko, impressed by her field control and refusal to escalate unnecessarily, flagged her for future deployment.
Their bond solidified during Royal Orders, when Areestes joined the Household Guard strike team for the assault on Mt. Buxanshal. During the engagement, Areestes was struck by a rampaging ancient mech and grievously injured—but refused to withdraw, continuing to fight with sheer determination. Her resilience and reliability on the field earned Mitsuko’s enduring respect.
Though their styles differ—Mitsuko measured and strategic, Areestes direct and often brash—they operate with mutual trust. Mitsuko views Areestes as one of her most dependable combat operators, someone she can deploy without second-guessing. Following Buxanshal, Areestes remained part of Mitsuko’s core tactical detail, solidifying her place among the trusted few the Princess Consort calls upon in moments of crisis.
Author Notes:
Mitsuko was originally conceived as a way for author Jenn Nixon’s Tiva Boon and JT Austin to hook up. The idea was a joke, but creating Mitsuko as an in-universe analog to Tiva prompted the author to create an older, less disciplined version of JT, which opened a lot of story possibilities.
If Suicide was originally modeled after Michelle Yeoh, Mitsuko was patterned after Ming Na Wen.
The planet Bonaparte, the Compact’s only monarchy, was created to flesh out her character background.
