Sheer Heart Attack, Part 2 / Heart Attack, Part 2.While Josuke and Okuyasu make their way to the scene, Kira appears before Koichi, knocking him out of Act 3's range and undoing the gravity on Sheer Heart Attack. Taking advantage of Act 3's limitations, Kira brutally beats Koichi, who uses the opportunity to learn Kira's real name. Just as Kira prepares to finish off Koichi using Killer Queen, Jotaro stops Kira and pummels him with Star Platinum. As Josuke arrives with Okuyasu to heal Jotaro and Koichi, Kira, having failed to pass himself off as an innocent bystander, chops off his own hand to set Sheer Heart Attack loose and escape. Using Crazy Diamond's ability to have Sheer Heart Attack reunite with Kira's hand and try to rejoin his body, Josuke and the others follow it to Salon Cinderella. They discover Kira has killed Aya after forcing her to replace his face with another person, allowing him to take on a new identity and hide once again.
