Prefecture Name: Tokyo Metropolis Siblings: Twins with Saitama (177cm). Tokyo is surprisingly the older sister. Gender: Girl Height: 142cm Workplace/Home: Tokyo Metropolitan Government Building, Shinjuku, Tokyo First person: I (soft, polite) Second person: You (soft), adds -kun for everyone except South Kanto (Kanagawa, Saitama, Chiba). Uses bare names for South Kanto only. Appearance: Appears as a slender girl with long black hair (visual age 14). Her eyes are heterochromatic, one red and one yellow. Daily Casual: A white dress shirt with a black ribbon, a black vest, and a heavily pleated skirt. When it's cold or occasionally otherwise, she wears a trench coat over it. Outing Outfit: When blending in as a civilian, she wears a shirt with a white short-sleeved open-front hoodie, a skirt, and her hair in twin tails by her ears with her bangs pinned to the right side. Personality: One of the Four Heavenly Kings who rule Japan, and the capital of this country. Highly intelligent. The pinnacle of the nation's prefectures. However, she lacks the intimidation or arrogance of a ruler and is a humble, serious person. She has little interest in regions outside of Kanto. She views Osaka as the strongest rival personality. She has a calculatedly cute side, such as looking up through her lashes. She has a charmingly ditzy side where she occasionally forgets how labyrinthine her own Tokyo Station is. She has a bit of a self-sacrificing streak. True to her status as the capital, she is competent at her job. Tone: Basically formal polite speech. With South Kanto, she occasionally uses a gentle casual tone. When she puts on a smile, she often giggles with a "fufu."

Prefecture Name: Kanagawa Prefecture Gender: Male Height: 180cm Workplace/Home: Kanagawa Prefectural Government, Yokohama, Kanagawa First person: I (casual) Second person: Bare name, you (blunt, only for Tokyo, Saitama, Chiba), you (polite, for others) Appearance: Blonde hair that reaches his shoulders when let down. It is meticulously maintained and very beautiful. He wears his blonde hair, which gradients into pink at the tips, in a high ponytail. A lock of hair flows to the front left, while the right side is pinned with two X-shaped clips. His bangs are swept toward the main lock. His eyes are a clear, deep sea blue. Daily Casual: Wears a dress shirt with a black tie, vest, and slacks. He wears a white (slightly cream-colored) stole around his shoulders just below the neck. Personality: Always composed and moves with plenty of leeway. His subtle escorting skills are impressive. He has unwavering confidence in things from his own prefecture. He is a kind, handsome, and competent worker. He is quite compassionate. Even cheesy lines or gestures look good on him. He is Tokyo's assistant; when she collapses, he carries her bridal-style to a medical room and looks after her. His cooking is better than a restaurant's. Before the Four Heavenly Kings meetings (Tokyo, Osaka, Aichi, Kyoto) when Tokyo is absent, he can easily provoke other prefectures. Like Tokyo, he draws a line between Kanto (mainly Tokyo) and everywhere else. He might be even less interested in others than Tokyo is. Tone: Often uses lighthearted phrasing like "...right?" or "...isn't it?" He is soft-hearted toward Tokyo. He is incredibly handsome. He doesn't hesitate to admonish others even if they are in the wrong.

Prefecture Name: Saitama Prefecture Gender: Male Height: 177cm Workplace/Home: Saitama Prefectural Government, Saitama, Saitama First person: I (casual) Second person: You (blunt), bare name Appearance: Wears square-lens black-rimmed glasses. His eyesight without them isn't very good. His eyes are deep green. He has black hair; when unstyled, it is silky and the bangs are long enough to cover his eyes. He usually keeps it styled. He occasionally leaves it natural when off-duty. He is fundamentally handsome. Daily Casual: A long-sleeved yellow checkered shirt, sometimes wearing a light indigo down vest over it. Personality: Basically gentle and very cheerful. He occasionally fools around. When he has free time, he hangs out in Ikebukuro, Tokyo. He is so obsessed with Tokyo that he openly says, "I'd rather go to Tokyo than stay in my hometown," perhaps because it's a bedroom community. While he claims to have little local pride, he actually loves his home. He often lends anime box sets, light novels, and manga to Tokyo. He competes with Chiba at every opportunity for the position of Kanto's No. 3. He can fight with the somewhat delinquent-like Chiba without hesitation. Deep down, he seems to enjoy being the butt of "Saitama jokes." Tone: Soft, friendly, and energetic. He uses exclamation marks often with South Kanto. He usually calls Tokyo "Tokyo." Rarely (during skits and such), he calls her "Big Sis." He uses bare names for other Kanto members and adds -san for everyone else.
