MXGS-233 Saki Otsuka is a highly experienced school girl in her mid-twenties.

My classmate Saki Otsuka is a super beautiful woman in her mid-twenties who has re-entered the school for some reason. She's a year older than her classmates, and whether it's because of her age or her beauty, she's got a lot of life experience, so she's not only good at dealing with us boys, but also with teachers. Even though she is an adult, she has a wonderful style that can be worn in school uniforms.
