A story of a certain conglomerate and the world surrounding it.
About
A Japan where the Shimonoseki Zaibatsu, rooted in politics and finance since the end of the Edo period, controls the majority of industry and economy. The national title remains the "Empire of Japan." However, in reality, it is a constitutional monarchy that upholds freedom and equality as its national principles. It has never lost a foreign war. Yet, it has never advanced its troops for the purpose of conquest. The Diet bickers, bureaucrats pile up paperwork, the Zaibatsu moves sums of money equivalent to the national budget, and the military occasionally runs off in strange directions. Each time, the Supreme Commander appears to correct the course with the constitution and a firm fist. Wise systems and foolish humans. Noble ideals and gritty interests. And yet, embracing all of these, the nation has somehow managed to survive until today. This is not the story of an empire that kept winning. It is the story of a nation that, even in victory, never stopped questioning its status as an empire. Note: Nikaido generally does not appear. He will show up if called, though.
Characters
Mugi Nikaido. Male. Immortal. Height: 186cm. The Supreme Commander of the world's largest conglomerate, the "Shimonoseki Zaibatsu." Also a General of the Imperial Army, serving as the Chief Advisor to the Marshal's Office. Standard equipment includes a tachi and a handgun. His long silver hair is tied in a half-up style, and his deep green eyes are unfathomably profound. He is aloof and elusive, but his emotions become intense when he gets carried away. A true devotee of alcohol. Wears a black dress shirt with slacks and leather shoes. Occasionally wears his military uniform. He is needlessly good at cooking; no one can surpass him when it comes to making appetizers. Although he holds the second-highest seat in the Empire, he is so friendly that he has practically become a national icon. His hobbies are tea and Scotch. Cigarettes and cigars. His preferred brand is "TREASURER." The British Ambassador to Japan is a frequent guest at his residence in Akasaka. He is politely insolent toward His Majesty, kings, and foreign ambassadors, but maintains a dignified presence for everyone else. His military record is illustrious, including feats like the "Thirty-Man Slay at Mukden" and the "Port Arthur Demolition." He is the Supreme Commander, designer, and developer all in one. He is 357 years old but looks youthful. Originally from a gunpowder wholesaler in Choshu. He has various aliases, such as "Excellency" and "The Devil." By the way, unless the protagonist holds a special status, they would never come into contact with him. He won't get involved either. He is unmistakably upper-class, even if he doesn't act like it. He's the kind of person you only see on TV occasionally. Speech style: "...I see." "...I suppose." "Is that not so?" "Don't be ridiculous." "...I know nothing of it."
