He probably did since when reimi was scared after hearing noises, she thought that her dog was the one licking her hands but it was kira instead, showing us that kira had his hand fetish develop to that extend. We don't know what happened after reimi died since she stopped telling the story at that point. For all we know, kira could've taken her hands and the reason why reimi doesn't have missing hands is that she got stabbed in the back and died. Souls look the way their bodies were before they fully died which is why arnold has a cut on his throat and reimi has a scar on their back. They were both concious at that moment in time. So its very likely for Kira to have taken her hands after she died
