The Girls' Magical Battle

Within my first hour after transmigrating, I started a world war. Lin En transmigrates into the world of Steel Valkyrie, a game he has beaten countless times, and becomes the Regent of a radically reimagined Britain. He loves the game, not only because it's a reimagined version of World War I with swords and magic, but also because the key figures from every country have all become soft and lovely girls. With the [Hearts of Iron System] at his disposal, surely he can lounge with beauties at his side and rule the world, right? Except nothing seems quite right. Why do all those other empresses seem like they haven't just started playing this game for the first time? He can't help thinking of all the affection levels he had maxed out. Over the long course of time, those values seem to have become distorted. In the first hour after he transmigrates, the world war begins. But why is this world war so wildly off-tone?! What do you mean the Ironblood Empire brought out assault rifles and a German-style monster squad in 1914? Why has the castle of the French knight-lords actually stood up and started walking? How does the Austro-Hungarian Empire really have the protection of heroic spirits? Why is every Russian a summoner? “Very well, Elizabeth. What do we have?” “The Empire's iron will?” And if he loses, he'll be turned into a cripple! Can he win?
