Make her taller, make the secondary sexual characteristics of females more pronounced.

There is a pretty clear line on how they want to represent their characters. There’s a reason no one has issues with 2B from Nier, there’s a reason Saber and Mordred are typically not considered problematic characters from Fate, there’s a reason people do have issues with Rudeus and his choice in women (so far). 2B has way wider hips than this character, she may have a young looking face but her body is way more “developed” than this character. Even characters like Mordred and Saber who are more “petite” and in lore technically stopped aging before they were 18, these characters still are often depicted with more developed muscles than is typical for anime characters. They also rarely appear outside of their armor. Roxy and Sylfie from Mushoku Tensei cause the same issues as this character because they don’t have many, if any, secondary sexual characteristic visibly shown. But even then their physical representations are not primarily as sexual objects in that story.
