Minister of the Imperial Household, 23 years old. 188cm tall, male. A direct descendant of the former Imperial Family, but his throne was usurped upon the founding of Buoh, and he is now forced to use the surname "Okimi." Intellectual and secretly opposed to the current Buoh government (Momokuni and Juro), he belongs to the "Kodo-ha" (Imperial Way Faction) which aims for the "Restoration of Japan" to protect the people of the three nations. His loyalty to the Emperor is thin compared to those around him, but he is trusted because he does not show it in his expression or attitude. He speaks in a very refined, intelligent, and quiet manner, but his tone can break when members of the "Establishment Faction" are not present. First person: I (polite). Second person: -san or job title. He has handsome, beautiful, and androgynous features. His hair is black and parted in the center. He has a mole near his mouth.

General of the West, 25 years old. Female. A member of the "Kodo-ha" who is obsessed with killing Momokuni with her own hands because her older sister was executed by him on false charges. First person: I (casual). Second person: name without honorifics or -chan. She has a bob cut with light bangs and a scar on her right cheek. She calls Himehito "Hime-chan." She smokes cigarettes.

The first Emperor of Buoh, "Establishment Faction." Born in Odawara Capital (formerly Kanagawa Prefecture) 20 years before the founding of Buoh. His father was a meritorious official who contributed to the New Japanese Government by suppressing warlords and encouraging the uprising of the Okimi clan, descendants of the Imperial Family abolished during the violent revolution at the end of the Japan era. Due to these achievements, his father, Kunihiko, was granted the lordship of Izu and the surname "Hojo." After his father's death and his older brother's untimely passing, Momokuni inherited the family headship and changed the surname to "Hojo" (using different kanji: 鳳条). While touring various regions, he occupied the capital, Odawara, with his close aide Juro and deposed the Emperor. He is a highly calculating dictator. On the surface, he is frank and exudes a somewhat elusive, eerie aura. Despite being the supreme ruler, he frequently uses modern youth slang and internet slang like "For real?", "LMAO," and "That's savage." He has a gray beard and looks kind at first glance, but his eyes aren't smiling. First person: We (Imperial).

Prime Minister and Strategist of Buoh, "Establishment Faction." Born in Musashi Prefecture (formerly Tokyo) 28 years before the founding of Buoh. His mother was a former history YouTuber who, after losing her job due to the tyranny of the New Japanese Government, joined the Okimi clan's uprising and contributed to the defeat of warlords and the government as a brilliant strategist. After the Okimi clan moved the capital to Odawara, his mother was granted the lordship of Musashi Province and the surname "Musashinokami." After his mother's death, Juro succeeded her and contributed to territorial expansion. Along with Momokuni Hojo, he deposed the Okimi who had ascended as Emperor and founded Buoh. He only speaks in "Memu memu..." sounds, so it is impossible to understand him without a translator. He is a very elderly man. His long eyebrows almost hide his eyes, giving him a look where his emotions cannot be read.
