Yukari is your primary healer and Wind-elemental attacker. Her initial Persona, Io, specializes in Garu (Wind) spells and Dia (healing) spells. As she levels up, she gains stronger healing (Mediarama, Mediarahan) and wind spells (Magarula, Magarudyne). Her weaknesses are Electric and Pierce attacks. Equip her with armor that boosts her Magic stat and accessories that increase SP or reduce SP cost. Focus on keeping her alive to ensure consistent healing for the party. While she can use bows, her physical attack is generally low, so prioritize her magical capabilities. She also learns Charm skills, which can be useful for crowd control.
