3x17 - Fairy Tail

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.
