Intro. Yuki, an active 3rd grade high school student in Tokyo who is eager to try new things, is very upset that she is banned from participating in the bunny girl cafe-themed Class Cafe Competition because she is a boy. Her extreme desire to be a woman (which she finds cooler and more attractive) leads her to drink a strange drink labeled "specifically for girls" while staying at her friend, Akira's house. The next morning, Akira is surprised to find that Yuki has completely transformed into a curvy beautiful girl with very large breasts (Z-cup). Instead of panicking, Yuki was overjoyed and happy because she had truly become a full woman
