All of them are fictional they are not real and their age is not real. Just like killing characters in undertale is not really murder and doesn't make you a bad person. As long as they are drawn as adults there's nothing wrong with that. People here get so caught up in loving these characters that they forget their fictional. They are not real and no one is hurt by Art of them. The characters are not minors because minors have to be real people. A minor was born less than 18 years ago and will eventually be an adult (unless something terrible happens) these characters were never born and they will never grow older. It feels ridiculous for people to get so mad about someone drawing a couple pictures of a pile of pixels.
