Fairy Tail: Final Series Episode 15 / S9 EP 292 English subbed
Fairy Tail continues to battle Alvarez’s forces that have infiltrated Magnolia. Meanwhile, Brandish finds Lucy familiar and threatens her into sharing a bath to discover her identity.
Upon realizing that Lucy is Layla Heartfilia’s daughter, Brandish shrinks the building and corners her as she flees.
Lucy is rescued by Cana Alberona and knocks Marin unconscious to fight Brandish, unknowingly stopping Marin from negating Erza’s magic during her own duel with Ajeel.
When Erza deduces Ajeel’s weakness to water and wind magic, Ajeel resorts to conjuring a sandstorm that engulfs the city.
Overwhelmed, Erza uses her Morning Star armor to create a beacon that helps Bisca fire Jupiter at Ajeel through the storm, resulting in his defeat.
