What Should I Do If My Husband Is the Moon Hashira?

- “Touken Ranbu special chapter now available. Thanks for your support!” You are a jujutsu sorcerer. You transmigrated. The good news: You're the legitimate daughter of a great clan, and you've been engaged since childhood to the heir of a feudal lord's family, with plenty of time to develop your relationship. The bad news: The heir ran away when he turned twenty. * Pursuing the ultimate swordsmanship and aiming to become the strongest swordsman in the world, he decided on a whim to abandon his family. He hadn't gone even half a li when his wife caught up with him and gave him a fierce slap across the back. Yoriichi let out a muffled groan, while his younger brother, Michikatsu, widened his eyes beside him. Tachibana Haru sneered. “Where are you going, husband, leaving home all by yourself?” Yoriichi: “...” Michikatsu: Σ(￣□￣;) The lady of the Tsugikuni family was decisive and swift in her actions, a rare thing in those days. Before she married, she'd been a celebrated young lady of virtue. Less than a year after marrying the head of the Tsugikuni family, she was already in charge of the entire household. Yoriichi was also extremely indulgent toward her. Caught between supreme swordsmanship and his wife, Yoriichi agonized over his choice. In the end, he handed Haru his head-of-family token. Haru's face lit up with joy. She promptly stuffed a bag of money into her husband's hands and gazed at him lovingly. “I understand that you're going away to study, dear. Please take this gold with you, and don't go without.” Then she turned to Michikatsu. “You must be my younger brother-in-law. You certainly are a fine, strapping young man.” Michikatsu kept his face stiff and didn't dare say a word. He could see that his elder brother's back was already starting to swell... His sister-in-law was terrifyingly strong! - In the Demon Slayer Corps, the Moon Hashira was always popular. Every month, the Moon Hashira would say goodbye to the master and make the slow journey back and forth to his home. Perhaps because he showed up from time to time, Haru was never much troubled by the Tsugikuni family's retainers. Besides, less than half a month after Yoriichi left home, she became pregnant. Who would dare talk back to the woman carrying the family head's only son? Haru was living the good life. Her husband grew more handsome by the day, gave her money, power, and a son, kept a low profile, had a good temper, and didn't take a bunch of concubines like other men of the era. At twenty-five, Yoriichi returned home, dispirited. Haru was delighted, thinking her battle-crazed husband had finally remembered his family responsibilities. - Starting one day, Haru began dreaming about Yoriichi, from the time he was her fiancé through their married life. She didn't tell her husband about it. Until one time, she dreamed about Yoriichi again and saw him kneeling alone beneath the moonlight. The moment she appeared, he turned his head. Six eyes stared at her, seeming to hold a trace of hatred. “My wife isn't you.” “You broke your promise.” When she awoke, Haru looked around their empty bedroom and felt relieved that her husband had gone out to kill demons. It had all been a dream. The next day, when her husband came home and she learned that he wanted to become a demon, Haru was left speechless: ...? - The Moon Hashira asked the master for a month's leave to go home. The master was puzzled and asked if he had been injured. After a moment's silence, the Moon Hashira slowly replied, “I... need to go home and fight a war. I'm sorry.” The master: “?” - 1. One-on-one romance, childhood sweethearts, a pure-love warrior, no pairing changes for Yoriichi (the six-eyed one counts, too). 2. No cursed spirits in this setting, only man-eating demons. The heroine's technique is still locked. If you can't understand her behavior, try thinking about Yoriichi's character. 3. Demon Slayer setting, but with unofficial Warring States history, so this is probably a history-inspired fanfic (?). The blurb suggests a romance, but the main story focuses on historical-style plot (highlighted!). Also, it's centered on Tsugikuni Michikatsu, covering his three periods as family head, Moon Hashira, and general. The Demon Slayer plot focuses on the Moon Hashira and Kokushibo periods, so don't read if you're looking for more Demon Slayer plot. 4. Content warning: childbirth, with painless childbirth (the family really does have a throne to pass down, ovo). This is an alternate history, so please don't nitpick the historical accuracy. No writing advice, and no attacking the author. The cover was commissioned personally, and commercial rights have been purchased. Take a look at my upcoming story! Same kind of Warring States setting: Becoming the Tsugikuni Family's Eldest Sister - My elder younger brother went mad, my younger younger brother became an idiot, and with tears in my eyes, I took on the burden of the Tsugikuni family. I became the next Hojo Masako, the next Lady of the Daitokuin, and successfully brought down the Ashikaga family, ushering in the Tsugikuni era. In my old age, I went on a tour of the Kyoto region and found two people facing off in a reed field. One was my idiot younger brother. The other was my elder younger brother, transformed into Belial. Those two idiots were about to fight each other! My guards stopped them. They both turned around. My foolish younger brother froze for a second, then dropped to his knees. My Belial of an elder brother's eyes went wide with shock x6, and he slowly knelt, too. “Big sister...” After I threatened and coaxed him, my elder younger brother turned me into a demon. Soon, I'd be able to stay young forever. When I learned that my elder younger brother had a formidable boss above him, I flew into a rage. How could I let someone else sleep beside my bed? Idiot younger brother, go get him! My ancient younger brother went off with his sword, shouting all the way. He killed my elder younger brother's boss, and somehow my elder younger brother became the new Demon King. Great work, big brother! You command the troops at night, and I'll change my name and become my own granddaughter. Together, we'll take out all those Northern ministers and generals...! My younger brother didn't want to become a demon and asked me if he'd go to hell. My elder brother glared at him (all six eyes). I gently told him that when people die, there's nothing left. Hell is nonsense, just a lie. “Big sister, where do people go when they die?” My foolish younger brother looked up at me hopefully. “Yoriichi, when people die, they all turn into rotten dog shit,” I said gently. “Big sister, that's too vulgar!” Kokushibo said, unable to hold back any longer. Kokushibo began to regret it. If he hadn't left all those years ago, perhaps Big Sister wouldn't have changed into the way she was now, caught in the whirlpool of power... Big Sister used to be so gentle! She just hit a little too hard! - My elder younger brother told me Yoriichi was the child of a god. I glanced at him and said pityingly, “Is there any difference between Yoriichi's brain and a banana?” My younger brother, now a demon, asked me, “Big sister, can you compare a banana to a brain like that?” I gave my elder brother an I-told-you-so look. Kokushibo: “...” * 1. A comedy full of jokes. The heroine is like Empress Lu and has transmigrated. (She's not Empress Lu, just that sort of person.) 2. The heroine is the eldest daughter of the Tsugikuni family. The story opens with the brothers' showdown in a reed field. 3. Please don't nitpick the historical accuracy. Don't attribute the characters' behavior to the author. The heroine is crazy, and this is an alternate-history fanfic. 4. The heroine has a husband, an adopted son-in-law who is already dead, and a ton of grandchildren. She supports puppet rulers, but remains the one truly in charge. Once the Warring States period is over, she leaves. Theme: Two hearts in perfect accord
