Diamond is Unbreakable - Chapter 87 
Yukako Yamagishi Dreams of Cinderella, Part 5 (岸由花子はシンデレラに憧れる その⑤ Yamagishi Yukako wa Shinderera ni Akogareru Sono 5), originally Annihilated Parts! (消滅した部品！ Shōmetsushita Buhin!) in the WSJ release, is the eighty-seventh chapter of Diamond is Unbreakable and the three hundred fifty-second chapter of the JoJo's Bizarre Adventure manga.
Several days later at school, Koichi reveals that he kissed Yukako to the bewildered Josuke and Okuyasu. Josuke tells Koichi that it is okay if he's willing, but Koichi then tells them that Yukako has been avoiding him ever since, not answering to phone calls and visits. Okuyasu and Josuke find that behavior strange, even for Yukako, but say that they can't help in this situation and that Koichi has to figure it out for himself. Later, Koichi sees a familiar silhouette in the streets and calls for the woman he recognizes as Yukako, but that woman turns back and reveals an ugly face completely different from Yukako's.
Apologizing for the mistake, Koichi leaves. However, the woman was really Yukako, who changes her mind and tries to call for him. Yukako barges into the Cinderella beauty salon and begins to attack Aya, ordering her to fix her face. However, Aya tells that no matter what Yukako does to her, she cannot change her face. As Yukako's fate breaks down, her body begins to as well. Suddenly Koichi enters the salon and asks for Yukako, who tries to tell him off, but he has recognized Yukako's forceful personality.
