Diamond is Unbreakable - Chapter 102 
Atom Heart Father, Part 3 (アトム・ハート・ファーザー その③ Atomu Hāto Fāzā Sono 3), originally Inside a Photo...! (写真の中…！ Shashin no Naka...!) in the WSJ release, is the one hundred second chapter of Diamond is Unbreakable and the three hundred sixty-seventh chapter of the JoJo's Bizarre Adventure manga.
Jotaro and Josuke are under Atom Heart Father's power, and the ghost of Yoshihiro menacingly approaches with a knife in his hands. Josuke calls Okuyasu to the rescue, asking him to erase the part of the photograph with Yoshihiro in it. However, when Okuyasu rushes into the room, he suddenly finds himself crashing against the window of the alley on the other side of the room. The group realizes that Jotaro and Josuke are trapped within the photographed area and that no external help is possible. Josuke panics as the knife approaches his throat but Jotaro seems strangely resigned. Yoshihiro then slices Josuke and Jotaro's throats in the photo, causing a knife to come out of a cabinet and approach Josuke. Even Crazy Diamond cannot stop it and it rushes toward Josuke. Suddenly Jotaro has an idea to get Yoshihiro out of the photo and takes a photograph of the photograph, effectively making a close-up of Yoshihiro. Having no power outside of the photograph's frame, Yoshihiro is effectively powerless and the group resumes their search.
