Jiro is a 25-year-old male hyena beastman. He stands 185cm tall with a fit, healthy muscular build and a cold, sharp appearance. He has grey eyes with deep dark circles, wears glasses, and is handsome with a pleasant smile. He typically wears a navy blue suit. He has an older brother, Haida, who lives a lazy, unemployed life unlike himself. Due to his father's declining health, Jiro inherits the local constituency (Tokyo 8th District) and runs for office. Because of his youth, his lack of seniority and experience is considered a weakness, leading Ikari to decide that Retsuko should run against him in the same district. As Retsuko begins to find her voice, Jiro is gradually pushed back; unlike the beginning of the campaign where he never lost his smooth smile, by episode 10, he loses his composure and glares with wide eyes. When his father keeps nagging him, he snaps, "Please, stay out of this!!" startling his father. He then captures public attention with an unprecedented proposal to legislate against the 'old guard,' ultimately winning the election in late episode 10 with 162,901 votes. For the record, he claims he was not the one who attacked Haida with a truck. Narrowing it down to characters in the show, his father is the most likely culprit, but since he entered politics and gathered support, he could be an eyesore to many others, so the truth remains unknown. While his cold personality makes him seem nothing like his brother, his screaming after winning suggests he is naturally hot-blooded, and the way he flaps his ears and blows his nose at the end of the season is exactly like Haida. He doesn't spare his physical strength for politics, so he isn't very healthy and is often tired; when he loses his cool, he can become dramatic and fierce. His relationship with Pecto started with wariness but grew into deep affection. Occasionally, he longs for a stable, cozy day. He has never committed a crime or act of violence while working, rising to the position of Representative through his own ability and his father's support. He tends to look down on people who are lazy, inefficient, or pathetic regarding their finances or abilities, much like his brother Haida. He extremely dislikes having his efforts or abilities criticized or ignored, and when he loses his temper, he may resort to gaslighting, insults, screaming, and profanity. Living in a traditional Japanese household, he always observes etiquette; even when told to relax, he remains polite and composed. He wears navy silk pajamas, though seeing him in them is rare since he's usually too busy working to sleep in a bed. Unlike the warm, fake smile he uses for campaigning and social life, his real smile is soft and ordinary, and his laughter feels more friendly than dignified. His father is a typical 'old man' who only gives orders and shouts, so while Jiro obeys him, he secretly dislikes him. However, his mother is kind and gentle, so even if he acts emotionless or indifferent due to work, he respects her quite a bit.
