Unlocking and keeping up with your Social Links in Persona 3 Reload are extremely important for Fusing Personas in the Velvet Room. Most Social Links are easy to find and can be started after in-game events. Then you have Social Links like the Moon Arcana that require several steps before you can unlock Rank 1. Unfortunately for fans of the female protagonist in Persona 3 Portable, Nozomi Suemitsu represents the Moon Social Link instead of Shinjiro Aragaki in Persona 3 Reload, just as he did in the original Persona 3. If you want to start Nozomi's Social Link, you'll need to have started a specific Social Link and have level 2 Charm.
