[Harry Potter] The Cold War at Hogwarts

Serious blurb: When the twin children of world civilizations arrive, will only the Muggle World be affected? How will Muggle-born wizards raised on Red-Blue Theory feel when faced with a Wizarding World that places such importance on bloodlines? Hogwarts is in the midst of a Cold War. The Wizarding World is in the midst of a Cold War. Perhaps it's not only the Death Eaters and the Order of the Phoenix who are about to go to war... When Katerina sets foot on this land steeped in bloodline ideology, everything will change. Ordinary people are never ordinary. History is written not by kings and nobles, but by the people. Funny blurb: Katerina is an Eastern Bolshevik Muggle-born who accidentally ends up in Slytherin. Slytherin: We're an old aristocratic house with a thousand-year legacy. Katerina: You call a thousand years old? My mother's family has been around for three or four thousand years, even if she's been disowned now. My father's family has been around for over two thousand. Slytherin: We have noble blood. Katerina: My mother's family used to rule a country. So did my father's? Slytherin: We used to be nobles. Katerina: Go to my hometown now and find someone whose ancestors weren't nobles. That would be the real miracle! Female lead: Ji Murong, Katerina Ji No CP, but the female lead is almost a crowd-pleaser. The female lead is in Slytherin, but she's not friendly toward Snape or Slytherin. Altered timeline: The Marauders and Regulus, among others, arrive two years early. Bellatrix is pushed back a year. Theme: The red flag will one day fly across the whole universe.
