Write a realistic, plausible alternate history scenario in the form of a history book chapter for both real life and Muv-Luv completely set in the world of Muv-Luv with absolutely no references to real life, OTL or that this is even an alternate history timeline at all set in the world of Muv-Luv, where the Meiji Restoration came after an earlier Boshin War in 1867 which ended with the main branch of the Tokugawa clan whose clan heads had been reigning over Japan as its shoguns since 1603 and anti-Shogun daimyo united for a common cause to overthrow the pro-western Japanese government, then under Tokugawa Yoshinobu as shogun of Japan and established the restoration of imperial rule in Japan with a new Shogun, Yoshinobu’s adopted son, Tokugawa Iesato, who ruled as Shogun of Japan from 1868 until his death in June 5, 1940 and the 5 Regent Houses of Koubuin, Ikaruga, Saionji, Kujo, and Takatsukasa from Muv-Luv being formed from and coexisting beside the main branch of the Tokugawa clan, with a Shogun being chosen from each Regent House one after the other after Iesato’s death via the Meiji Restoration, which made the Tokugawa shogunate the local government of Japan and its provinces of Korea, Taiwan and the Pengu Islands and Sakhalin and the Kurils while the heads of the main branch of the supposedly Shinto descended, Japanese Imperial House of Great Yamato/Minamoto dynasty ruling over Japan as its Emperors and Empresses respectively became combined constitutional imperial royal heads of state and of the Japanese armed forces with the right to select the Japanese Prime Minister and also to preside over the Japanese National Diet via the 3 January 1868 Meiji Restoration in the Tokugawa shogunate in the world of Muv-Luv, with Japan experiencing an accelerated rate of the industrial, economic, military and cultural and technological growth it had during, via and after the Meiji Restoration in real life in the world of Muv-Luv while the hereditary vassals with many generations of direct service to the Shogun, and by extension, the Regent Houses, under their name, with many of them serving in important positions known as the fudai from Muv-Luv are also formed via the Meiji Restoration. 

The Japanese Empire is still formed as the government of Japan via and due to  the Meiji Restoration like in real life and in canon Muv-Luv but the Japanese Empire's hereditary peerage, the Kazoku [magnificent lineage] is formed from the samurai and daimyo instead of both classes being abolished via and after the Meiji Restoration like in real life. 

The Kazoku is below the fudai in the social rankings of the Japanese aristocracy and nobility.

Japan never lost the Greater East Asian War of 1932-1947 like in canon Muv-Luv and in real life and keeps its overseas provinces of Korea, Taiwan and the Pengu Islands and Sakhalin and the Kurils indefinately post-1947 as a result due to Chiang Kai-shek being killed after the 1926-1928 Northern Expedition, causing the Ming to be restored as the government of the sixteen provinces of Han minus Guangdong and Guangxi with the descendants of the Ming dynasty's imperial family, the Imperial House of Zhu, being enthroned as the restored Ming dynasty's reigning imperial family, while Manchukuo, under the rule of the reigning Qing imperial family, the Manchu Imperial House of Aisin-Gioro and Mengjiang under the rule of Genghis Khan's descendants, the main branch of the Imperial House of Borjigin in Manchuria [Manchukuo] and Inner Mongolia's Chahar and Suiyan provinces [Mengjiang] are [Manchukuo and Mengjiang] both [Manchukuo and Mengjiang] formed immediately after the Ming restoration in 1928 instead of in 1932 and 1939 like in real life, though as Japanese protectorates as in real life with the restored Ming becoming a Japanese protectorate as well, while KMT republican loyalists opposed to Kai-shek move back to Guangdong and Guangxi and form a independent Cantonese Republic, which also becomes a Japanese protectorate, which means Japan never attacks Pearl Harbor, strikes North into the Soviet East Coast and Soviet-occupied Mongolia first before striking Western colonial occupation of Asia and liberates the Kingdom of Hawaii in Hawaii via covert operations, along with the Second Philippines Republic in the Philippines preventing US intervention and giving the Nazis enough time to nuke Moscow, NYC and Washington D.C with experimental nuclear tipped ICBMs, plunging the Anglo-American alliance and the rest of the Allies into chaos and ending the USSR in a joint Japanese-Nazi invasion.

After the war, Germany proper inclusive of the Prussian territories and the Sudetenland separates from Nazi Germany and restores the Weimar Republic, while the remains of Nazi Germany in Greater Austria absorb Horthy's Hungary, the German puppet state of the Republic of Slovakia in Slovakia, the joint Italian-German puppet state of the Independent State of Croatia in Croatia and Bosnia and Herzegovina and Czechia minus the Sudetenland and subsequently after this become a restored Austria-Hungary ruled by the Hapsburgs once more as its reigning imperial family. 

The USA is humilated and subsequently divided with a Japanese controlled West Coast, a Austria-Hungarian controlled East Coast and a British-controlled neo-Confederate States in the Southern USA, with the restored Weimar Germany quickly transitioning towards a restored Kingdom of Prussia-ruled and dominated German Empire with the proported descendants of Adolf Hitler, who is said in Germany to be pre Weimar Imperial Germany’s last Kaiser: Wilhelm II’s of the Kingdom of Prussia's reigning royal family's the German House of Hohenzollern’s Gippsland, Australia-born openly gay nephew [Adolf] and Wilhelm II’s chosen successor [Adolf] as German Kaiser, who [Adolf] had the illegitimate son of Austria’s last Kaiser; Franz Josef I of the House of Hapsburg-Lorraine, Sebastian von Hapsburg as his [Adolf's] life partner, making Sebastian and Adolf Nazi Germany’s imperial couple [Adolf and Sebastian] with Adolf succeeding Willhelm II as German Kaiser in 1943, but due to Adolf’s sperm being stolen from him [Adolf] by the Russian Jewish mafia and [Adolf's sperm] subsequently [Adolf's sperm] used to impregnate the part-Polish illegitimate daughter of Soviet dictator Josef Stalin, who was in fact the illegitimate son [Josef] of Imperial Russia’s last Empress: Princess Alix of the German House of Hesse-Darmstadt, then the children born via Adolf's sprem being used to impregnate Stalin's daughter then had children with Sebastian’s descendants in Gippsland, Australia, who were brought to Germany by Wehrmacht loyalists and made the current German imperial family.

The  large bipedal machines, and primary weapon system developed as all-purpose assault units, able to fight in urban areas, on uneven terrain, and 3-dimensional combat, without their maneuverability being constrained in the heat of battle, whose movement is a combination of bipedal locomotion and thrust, whose legs and arms are moved with carbon actuators, superconducting bands of carbon-based material that expand and contract based on the electrical current passed though them; the electricity to power the carbon actuators come from a combination of batteries and magnesium fuel cells, along with also being armored in an anti-projectile and heat-resistant composite that has been further treated with anti-laser coating, equipped with high-output particle cannons along with advanced rocketry and plasma cannons, known as Tactical Surface Fighters from Muv-Luv are still developed by Western Europe and the Empire of Japan in 1974, but the menacing, scary, using biotechnology in both civilian and military usage, extraterrestrial aggressive race named BETA by the humans of Earth from Muv-Luv never arrive on the moon in the 1950s like canon Muv-Luv.
