Fairy Tail: Final Series

Synopsis

Erza successfully obliterates Irene's meteor, while Wendy enchants Erza's sword with Dragon Slayer magic to injure Irene, but the two are unable to defeat her. As Irene prepares to kill Erza, she remembers her decision to spare her newborn daughter's life and leave her for adoption; realizing that she still loves Erza, Irene impales herself with her daughter's sword, leaving Erza to pay her respects to her mother. Meanwhile, Igneel instructs Natsu to survive by destroying one of the seeds in his body, which risks turning him into either a dragon or a demon; Natsu instead asserts his identity as a human and destroys both seeds. Natsu revives shortly before Universe One's effects wear off, reverting Fiore to its original shape and sending Fairy Tail's members back to Magnolia, where Natsu and his friends prepare to return to the guildhall.
