In Persona 3 Reload, you'll be able to purchase various weapons from the Police Station in Paulownia Mall. As you progress through the story, you'll unlock a store called Mayoido Antiques. Here, you can use special materials found in Tartarus to craft exclusive weapons, armor, and accessories. Once you can go to Mayoido Antiques in your Persona 3 Reload playthrough, you'll start receiving Requests from Elizabeth asking you to bring specific weapons that can only be crafted. One of these is the Mikazuki Munechika, a Slash-based weapon for Junpei Iori.
