The richest girl in Shinchan is Ai Suotome. She's a five-year-old girl, Shinnosuke's classmate, and known for her wealthy family background.
Ai consistently flaunts her wealth, often looking down on her less well-off classmates. Her family's wealth is implied through various signs:
- Luxurious lifestyle: Ai lives in a large mansion, travels in a chauffeur-driven car, and enjoys many privileges.
- Expensive possessions: She often carries designer toys and wears extravagant clothes.
- Family background: Her father, Masao Suotome, is an architect, suggesting a high-income profession.
While other characters like Shinko, a classmate, and Kazama, a wealthy boy, are also mentioned, they lack the consistent portrayal of wealth as Ai does.
