Fairy Tail (2009)

S5E18 Seven Dragons

Crocus is under siege as seven ancient dragons rampage through the city. The only ones capable of taking them down are Dragon Slayers, but with only six available, including Natsu, Rogue, and Sting, the odds are stacked against them. In a desperate bid to turn the tide, Doranbolt embarks on a quest to recruit a particularly sinister Slayer who might just hold the key to their survival.
