Jirou Haida is "Haida"'s younger brother and Retsuko's opponent in the election for the House of Representatives. He serves as an antagonist for Season 5 of Aggretsuko.

Appearance
Jirou's appearance is based on a spotted hyena. Jirou shares very similar looks with his brother as both having grayish brown fur and a black nose and ears. Unlike his brother he has a lighter grey muzzle and tufts of fur on the end of his cheeks. He also has a tuft of fur on the top of his head which, unlike the color of his body that is grayish brown is all gray. He has grayish-brown freckle like spots on his cheek and has tufts of fur in his ears.

Jirou has been seen wearing a navy suit with a white dress shirt. He also wears a navy tie and wears silver half rim glasses.

Personality
Compared to his older brother, Jirou is more self-assured and prideful, owing to being the more gifted child in his family. He is cunning, knowing how to play his brother like a fiddle, and also charismatic enough to win himself over for the masses. However, he does have his own standards, namely breaking away from Juzo after learning that Haida almost got hit by a car.
