Cana finds Mavis's grave and reflects on her reasons for becoming an S-Class wizard: her father is revealed to be Gildarts, who is unaware of his relationship with her, leading the younger, timid Cana to decide to become an S-Class wizard and bolster her own confidence to reveal the truth to him. However, Cana realizes that she had also betrayed Lucy in her determination. Wracked with guilt, Cana takes the Fairy Glitter spell from the grave and uses an enchanted card leading her to Lucy as she and her friends are attacked by Bluenote. She tries to perform the spell on Bluenote, but fails. However, she is saved when Gildarts arrives and attacks Bluenote.

Gildarts fights Bluenote while Fried and Bickslow, who returned to Tenrou Island together with him, help Levy, Lisanna, and Pantherlily to fight Rustyrose. Meanwhile, Azuma reveals to Erza that he has used his magic, the Great Tree Arc, to absorb the magic-giving energy of the island's giant Tenrou Tree, destroying it and draining the strength of all the Fairy Tail members on the island except Erza.

Erza makes Azuma promise to return her guild's magical power if she defeats him. She herself is nearly defeated when Azuma uses the Tenrou Tree's magic, but receives her second wind upon hearing Jellal's voice and, drawing power from the tree's magic, cuts Azuma down

Azuma transforms into a tree as a result of overusing his Great Tree Ark, but makes good on his promise to Erza and returns the guild's magical power, giving Gildarts, Fried and Bickslow enough strength to defeat Bluenote and Rustyrose. Meanwhile, Ultear tells Gray that the only spell that can defeat Hades is Iced Shell. She then takes Zeref and returns to Meldy, revealing to her that she is actually trying to manipulate Gray into defeating Hades for her so she can keep Zeref for herself. However, Gray is unfooled by her deception and, catching onto her true motives, challenges her.
