Successfully complete the game to unlock New Game+ mode. This mode allows you to carry over all skill cards, social stats, money, Persona compendium, weapons, armor, and other pieces of equipment to your next playthrough. However, character level, cooperation level, equipped Personas, consumable items (Valentine's Chocolates remain), and items except weapons, armor, and other pieces of equipment do not carry over to the next playthrough. Additionally, battling Caroline and Justine, fusing Satanael, and an extra difficulty mode are part of New Game+ mode.
