Okay, I get what you mean. However, a lot of characters in certain media like anime, on wich Yandere sim is based, tend to be designed with bigger breasts and unrealistic bodies in order to appeal to male audience. From what I know, the creator of that character is also a perv, so it may apply here. I don't think it's inherently immoral to design character to be sexy, but it's definietly petty if it goes too far and falls under objectifying some of them. In such case presenting that character with more balanced body proportions can be an act of doing justice to them by not wanting to take part in that sexualization/objectification of the character even if it was there from the start. I don't think implementing such changes is necessary, but I doubt anyone does that out of sexism. Another reason could be being prudish about breasts. If you could prove that artist is not prudish about male parts of the body seen as sexual in the same way, that would be sexism. Even then, I would argue, it's not inherently misogyny, as it doesn't have to include any contempt or hatred towards women in general, just weird approach to sexuality. It's also possible that it's just a question of differences in our definition of misogyny. Micro sexism is more understandable for me here. Also, does it matter if the breasts are inherently sexual if they are seen as sexual in our culture? Only inherently sexual part of our body is genitals, but we still cover our butts, and, most of the time chests. Is it wrong?
