Chapter 17: The First Battle
Three weeks into the marriage
Koko discovered the rice contract by accident.
Mio was in her workroom, reviewing the provisioning schedules, when she heard raised voices from Shabazu Matsui’s study.
“You let her negotiate household contracts?” Koko’s voice, sharp with fury. “Without consulting me? Without my approval?”
“She drafted the contract. Taichi executed it. And we’re saving over seven hundred ryō as a result. I fail to see the problem.” Matsui’s voice was calm, which seemed to enrage Koko further.
“The problem is that she’s a merchant’s daughter pretending to understand samurai household management! The problem is that you’re giving her authority that rightfully belongs to me! I’ve been managing this household for thirty years—”
“And in thirty years, we’ve been slowly going bankrupt. In three weeks, Mio identified the problem, researched solutions, and fixed it. That’s not pretending—that’s competence.”
Mio sat frozen in her workroom, heart pounding.
He’s defending me. To his own wife. Because of my work.
But this was dangerous. Very dangerous. Koko would retaliate.
“Competence?” Koko’s voice dripped venom. “She went to the market. Dressed as a servant. Investigating prices like some common merchant.”
How did she find out?
“She did what was necessary to gather accurate information. Something you might have done yourself if you’d cared more about the household finances than maintaining appearances.”
The silence that followed was deadly.
Then Koko’s voice, cold and controlled: “You’ve made your position clear, husband. But understand this—I won’t have that girl undermining my authority in my own household. If you want her playing merchant, fine. But she does it quietly, secretly, and she shows me proper deference in all other matters. Or I will make her life here unbearable.”
“You’ll do no such thing.”
“Won’t I? I’m the mother of your heir. I’ve been mistress of this household for three decades. I have servants who are loyal to me, allies among our relatives, social connections you depend on. If I choose to make trouble for your merchant bride, you’ll find it very difficult to stop me.”
Footsteps. Koko was leaving.
Mio had just enough time to arrange herself in a proper needlework pose before Koko swept past her workroom, not even glancing inside.
But Mio felt the fury radiating from her like heat from a forge.
This is going to get worse, Mio thought. Much worse.
That evening, Koko summoned Mio to her chambers.
Not her workroom. Her private chambers. This was unprecedented—and definitely not good.
Mio dressed with extra care, made sure her posture was perfect, her expression serene, and knocked on the shoji with appropriate deference.
“Enter.”
Koko’s chambers were elegant, expensive, and cold. Like their owner.
Koko sat in the position of authority, backlit by the sunset through the window. It was deliberately staged to put Mio at a disadvantage.
Mio knelt and bowed deeply. “You summoned me, honored mother?”
“Yes. We need to discuss your role in this household.”
“Of course, honored mother.”
“You’ve been here three weeks. In that time, you’ve somehow convinced my husband and my son that you have valuable skills. That your merchant-class education makes you useful.” Koko’s voice was like ice. “I want to be very clear with you about something: I don’t care what they think. I know what you are. And I won’t allow you to corrupt this household with commercial thinking and merchant values.”
Mio kept her eyes lowered, her voice soft: “I have no intention of corrupting anything, honored mother. I only wish to serve this household to the best of my abilities.”
“By going to the market dressed as a servant? By negotiating with merchants like you’re one of them? By demonstrating exactly the kind of low-class behavior that proves you don’t belong here?”
Each accusation was designed to provoke a reaction. Mio gave none.
“I apologize if my actions were inappropriate, honored mother. I was attempting to help with household management, but I clearly overstepped. It won’t happen again.”
“No. It won’t. Because from now on, all household management goes through me. All contracts, all negotiations, all financial decisions—I approve them before they’re executed. You may assist with paperwork if my husband insists, but you have no authority to act independently. Is that clear?”
It was a direct power grab. Koko was trying to neutralize Mio’s effectiveness by requiring approval for everything.
But Mio had anticipated this.
“Perfectly clear, honored mother. I will defer to your superior experience and judgment in all matters.”
Koko’s eyes narrowed. She’d expected resistance, argument, defense. Perfect compliance was harder to attack.
“Furthermore,” Koko continued, “I’m assigning you additional duties. You’ll be responsible for the household shrine maintenance—daily offerings, seasonal ceremonies, ensuring proper respect is shown to our ancestors. You’ll also oversee the servants’ training, the garden maintenance schedule, and the preparation of all formal meals for guests.”
It was a crushing workload—designed to leave Mio with no time for anything else. Particularly financial analysis.
“Yes, honored mother. I’m honored by your trust in assigning me these important responsibilities.”
“Don’t misunderstand. This isn’t trust. This is me ensuring you’re too busy with appropriate wifely duties to interfere in matters beyond your understanding.”
“I understand, honored mother.”
Koko leaned forward. “Do you? Do you understand that no matter how clever you think you are, no matter how much my husband and son value your merchant tricks, you will never be truly samurai? You’ll never be one of us. You’re a purchased commodity playing a role, and the moment you forget that, I’ll make sure everyone else remembers it.”
The cruelty was breathtaking.
But Mio had been forged in eight months of transformation. She’d been broken down and rebuilt. She’d learned to hide steel beneath silk.
She bowed deeply. “Thank you for your honesty, honored mother. I will remember my place.”
“See that you do. You’re dismissed.”
Mio rose, bowed again, and left with perfect composure.
She made it all the way to her chamber before her hands started shaking.
Taichi found her there an hour later, kneeling in the darkness.
“Mio? Why aren’t there any lanterns lit?”
“I was thinking.”
He lit a lantern and saw her face. “What happened?”
“Your mother happened.” Mio’s voice was flat. “She’s assigned me enough duties to fill eighteen hours a day. She’s requiring approval for all household management decisions. And she made it very clear that I’m a purchased commodity who will never truly belong here.”
Taichi’s expression darkened. “She said that to you?”
“Among other things.”
“I’ll talk to her—”
“No.” Mio’s voice was sharp. “Don’t. That’s exactly what she wants. She wants you to defend me so she can paint me as someone who runs to her husband for protection. Someone weak who can’t handle samurai household management.”
“But this is unreasonable—”
“Of course it’s unreasonable. It’s warfare.” Mio looked up at him. “Your mother is fighting for control of this household. She sees me as a threat to her authority, and she’s using every weapon she has to neutralize me.”
“So what do we do?”
Mio took a breath, thinking it through. “I do exactly what she asked. All of it. Perfectly.”
“That’s impossible. No one can manage that workload—”
“I can. I’m very good at time management.” Mio stood, her strategic mind already working. “I’ll handle the shrine, the servants, the garden, the formal meals—all of it. Flawlessly. Give her nothing to criticize.”
“And the financial work?”
“I’ll do it at night. When she’s asleep. I’ll bring ledgers here, work by dim light, and have everything back in place before dawn.”
Taichi stared at her. “You’ll work yourself to exhaustion.”
“Better exhausted than defeated.” Mio’s voice was steel now. “Your mother wants to break me. Make me fail. Prove I’m unsuitable. I won’t give her that satisfaction.”
“Mio, this is insane—”
“This is war. And I know how to fight wars, Taichi. My father taught me. When someone tries to squeeze you, you don’t push back directly—you slip sideways and hit them from an unexpected angle.”
“What does that mean?”
