All right, let's stop right there. You're making the classic mistake of conflating the moe art style with lolicon. There may be a lot of overlap, but they're not the same thing. The commonly agreed upon definition for a loli is a young girl at an early age of adolescence who has yet to develop the physical characteristics of an adult woman.

This character is canonically nineteen and her chest size clearly indicates that she is outside of the loli age range. The VN she comes from simply draws all of its characters in the exaggeratedly cute moe style, including her mother and the school nurse.
