Objective: Defeat all Legionnaires and rescue Ryuji. This mission introduces more enemies and the '1 MORE!' system. You'll have Joker, Erina, and eventually Ryuji in your party. Focus on exploiting enemy weaknesses. Most early Legionnaires are weak to physical attacks or specific elemental Personas. Use Joker's Persona skills to target weaknesses, knocking down enemies to trigger '1 MORE!' actions. Once Ryuji joins, utilize his powerful physical attacks to finish off vulnerable foes. Remember to use cover effectively, as enemies will now attempt to flank you. Prioritize taking out ranged enemies first, as they can deal consistent damage from a distance. Keep your party members spread out to avoid area-of-effect attacks. The key to success here is chaining '1 MORE!' actions to clear the battlefield efficiently.
