Kimura serves as a designer within the Animal Design Department, tasked with creating diverse animal species. He possesses a very tall stature, a somewhat muscular build, short brown hair, and hazel eyes. His standard attire is semi-formal, typically featuring brown slacks, a green blazer, a white shirt, and formal shoes.

A defining obsession drives Kimura: creating animals that are tasty or edible. This culinary fixation is central to his design philosophy, heavily influencing his priorities. He frequently attempts to sample animals designed by colleagues, even those potentially toxic or dangerous. Despite this quirk, he consistently exhibits a jolly and enthusiastic demeanor towards his work.

Within the department, Kimura is recognized for his carefree attitude and rarely engages in arguments. He occasionally adopts a detective-like persona to investigate team mysteries. His professional approach emphasizes practicality and functionality in meeting design requirements, though the edible criterion remains paramount.

His most celebrated creation, considered his masterpiece, is the cow. Other notable designs attributed to him include the crab, sea cucumber, starfish, crayfish, elk, Iberian ribbed newt, zebra moray, and blowfish. He also contributed to conceptualizing an alien lifeform.

Kimura operates under the celestial theme name "Jupiter," aligning with the team's naming convention. His interactions with colleagues are generally harmonious, though occasional conflicts arise, particularly with Mercury, who disapproves of his habit of consuming experimental prototypes. These conflicts do not significantly disrupt the overall team dynamic.
