Satoru Nakae (中江 悟 Nakae Satoru) is a tertiary character featured in the fourth part of the JoJo's Bizarre Adventure series, Diamond is Unbreakable. During the investigation, Hayato Kawajiri witnessed him and his girlfriend Minako Okura getting killed by Yoshikage Kira.
Satoru is a tall 22 year old man of muscular build. He is a third-year student at S-City M Community College, sporting a buzz cut and his attire consists of a long sleeve, striped crop-top shirt, baggy pants, circular earrings and glasses (In the anime, the glasses are depicted with a green tint).
Satoru, much like his girlfriend, is seemingly quite rude and quick to make bold assumptions about others. He and his girlfriend, Minako Okura, are quick to assume Kira is a thief despite the latter merely pushing Minako's bag off his lap. They are also willing to quickly shift blame onto Kira for them bumping into him despite their carelessness being the cause. Despite this shared trait, they're both seen being intimate with each other in as a happy couple.
Satoru Nakae is introduced as a young man who is seen riding the train Kira takes home from work, being complained to by his girlfriend Minako Okura, about her supposedly overbearing father. At some point, she ran away from home and moved in with Satoru, but still kept in contact with her mother. As she told the story enthusiastically to her boyfriend, they were unaware that Kira was sitting next to them, trying to control his killer instincts. Bothered by her bag being on top of his leg, Kira pushed it away, and the couple accused him of trying to steal it.
As they got off the train, Satoru and Kira bumped into each other, knocking Kira's things to the ground. Satoru yelled at Kira again, and the couple mocked his "lame" nail clippers. Tired of the repeated confrontations, Kira followed the couple home.
Entering the apartment just as Satoru promised to buy her a new pair of earrings, Kira blew him up instantly with Killer Queen. Unable to resist his desires any longer, he forced Minako to cut his fingernails. Just before blowing her up, Kira took her boyfriend's ears and hung them on her own, telling her that her boyfriend had left some earrings behind for her. After killing Minako, Kira took her hand as his new "girlfriend" and planned to take it with him to Kosaku's house, but was forced to destroy the hand after seeing Hayato leaving the scene with a camera.
- “Well you do party too much. So I bet you and your dad had a big fight, huh?”
- “Is he a pickpocket? Or a perv trying to cop a feel? Want me to teach him a lesson? Hell, say the word and I'll kill him!”
- “Hey, that hurt! What the hell's your problem? Could you get off the train any slower?”
- “What the hell man?! This is my apartment!”
