Fairy Tail : Season 6

While relaxing in their new bathhouse, the Fairy Tail women get a surprising, and not entirely welcome, visitor. Later, Natsu and Gray specifically get a job request from Warrod Seeken, 4th-ranked member of one of the Ten Wizard Saints. But what mission could a wizard of his stature have in mind for Fairy Tail?

After arriving at the frozen Sun Village, the members of Fairy Tail try to figure out a way to defrost everything, but are interrupted by a trio of treasure hunters who may have the key to melting the otherwise indestructible ice... except they're only interested in taking the village's Eternal Flame for themselves.

Erza is confronted by Minerva, who doesn't mind that her opponent is in a weakened child form. Now Minerva belongs to a dark guild, Succubus Eye, and her partner faces off against Natsu, who has also been reverted to childlike form. And Sun Village with its giant residents is still supernaturally frozen over...

With Flare's heroic arrival at the village, the odds are a bit evened, so it's Lucy, Wendy, and Flare versus the three sexist treasure hunters of Sylph Labyrinth! Meanwhile, Natsu keeps following that mysterious voice, while Erza in child form gets a whupping from Minerva!

Gray's duel with Doriate is one-sided when his childlike form can't produce enough power to deal any damage. Meanwhile, the other members of Fairy Tail find the Eternal Flame... but it's frozen solid. Making matters worse, a ravenous giant monster appears...

As Natsu battles the formidable winged cyclops monster, Gray enacts his plan to melt the mountain of ice encasing the Eternal Flame... but does he end up extinguishing that along with it? Plus: the identity of the familiar voice that called out to Natsu, bringing him to the frozen Eternal Flame!

Natsu and the other Fairy Tail wizards help celebrate Flare's homecoming in the defrosted Sun Village. Meanwhile, Minerva returns to the Succubus Eye guild, only to find a member of Tartarus waiting for her. Later, the Fairy Tail wizards make it back to Warrod's house for rest, relaxation, and a revelation about his past!

The Magic Council is having a meeting about the mysteriously-disappearing dark guilds when they're attacked by a powerful force, the harbinger of the Tartarus threat that will derail Fairy Tail's recent relative peace and quiet.

The battle between Laxus and Tempesta ends with all the members of the Raijinshuu lying near death. Natsu and all the other Fairy Tail members want to avenge them, but Tartaros's whereabouts are unknown. Meanwhile, the demonic members of Tartaros begin to get intrigued with Fairy Tail...

Natsu foiled the initial attempt on Michello's life, but now he has to battle Jackal, one of the Nine Demon Gates, to keep the former Magic Council member safe. It's a hard fight, especially since Jackal has the power to make anything he touches (or that touches him) explode.

Natsu has a final showdown with Jackal, who turns himself into a human bomb at one point! Later, the other teams arrive too late, finding the other former members they're meant to protect already murdered by Tartaros...

While Franmalth attempts to absorb Natsu and Lucy's souls, Mirajane discovers the secret to the demons' immortality in Hell's Core, right before Seilah unleashes the restraints on her own power to take on Mira.
