After Maxing Out My Palace Intrigue Skills, I Reincarnated into the Zenin Clan

[The blurb has been screenshotted] Q: What do you get for spending five hundred yuan on a single-player palace-intrigue game? A: Countless skills, more poison than you could ever use, unlimited saves, and absolute say over the game. Q: What happens if you take a palace-intrigue game like that with you when you die and are reborn as an illegitimate daughter from a branch family of the Zenin clan? A: ... Zenin Shinku: No idea. Does making Rainbow Piggy kneel on my first day count? = Shinku's life as an overworked office drone made her fall in love with a single-player palace-intrigue game. It was simple, didn't pressure her to spend money, and required no socializing with real people, making it a great way to unwind. Shinku's life as an overworked office drone made her open her eyes again, only to find herself a pitiful little girl on the verge of freezing to death in the Zenin clan. Three months after her reincarnation, Shinku decided to give the Zenin clan a taste of true feudal (palace-intrigue) upheaval. Hey, you there, you fat pig who used to bully me. Where'd you go? Oh, almost forgot. Shinku already poisoned him and pinned it on another pig~ Dear Zenin clan, I hope you can withstand the trials of Shinku, a seasoned palace-clearing expert~ = On Shinku's first day of high school, she rode in on a sedan chair. She decided to give her classmates a taste of the shock of a venomous beauty, for example... "All right, all right." Maki yanked Shinku off the sedan chair and gathered her into her arms. "Let me introduce you all. This is Shinku, my little sister. She's all bark and a softie at heart." After killing everyone in the Zenin clan until only her sisters' family was left, Shinku realized people really could tell who she'd killed. She had no choice but to reload and kill a few fewer people. Zenin Shinku: (smiling sweetly) Shinku: From now on, I won't tolerate anything filthy in my sight. Oh, right, right, right. How come no one asked what Shinku did for work before? It's nothing important, though. Her boss just happened to be a pervert whose name starts with Mori. P.S. 1. No research or historical accuracy. Feudalism versus feudalism, an absolutely epic clash. 2. The heroine kills without batting an eye and has an innocent, cruel streak, but she doesn't kill indiscriminately. 3. Palace-intrigue games really are a great way to unwind. (Hey!) 4. Stay or go as you please, but don't insult me. (Runs off with a wok over her head.) Theme: Moving into a new era
