Natsu Dragneel & Gajeel Redfox vs. Tempester & Torafuzar

Natsu Dragneel & Gajeel Redfox vs. Tempesta & Torafusa is a fight fought between Dragon Slayer Mages of Fairy Tail, Natsu Dragneel and Gajeel Redfox, and Nine Demon Gates of Tartarus, Tempesta and Torafusa.

Prologue
Having defeated Jackal, Lucy finds herself in a danger from multiple Demons and thus, Natsu, Juvia, Gray and Gajeel rush to her aid against Tempesta, Keith, Silver and Torafusa. While Silver transports Gray to another location, Tempesta initiates his Curse, creating multiple tornados. However, this is proven to be ineffective against Gajeel, who rushes to attack the Demon, but is intercepted by Torafusa. The Fairies are seemingly at a disadvantage as Natsu is unable to strike Keith and all three Mages are then pushed down by their opponents' attacks. Not even this dampens their determination as Fairy Tail Mages get up, with the Demons stating that this is just a beginning.

Battle
The battle heats up, with Natsu dodging Tempesta's attack just to strike back, however, the Fire Dragon Slayer's attack is effortlessly blocked by the Demon. At the same time, Gajeel keeps exchanging blows with Torafusa, until he and Natsu attempt to grab their respective opponents and throw them against each other, but, with the use of his Curse, Tempesta stops this plan and Natsu and Gajeel are the ones to be thrown into a wall. Worried, Lucy attempts to help, but Natsu reassures her, telling her to rest. Both Natsu and Gajeel then simultaneously attack their opponents. However, Natsu's attacks do not seem to have much effect as Tempesta instantly retaliates, while Gajeel and Torafusa compliment each other for their prowess.

After Juvia defeats Keith, both sides decide it's time to get serious as Tempesta and Torafusa enter their Etherious forms, while Natsu and Gajeel activate their Lightning Flame Dragon Mode and Iron Shadow Dragon Mode respectively. The two Dragon Slayers briefly argue about who is stronger until they decide to make a bet - whoever defeats their enemy first will get a song from the loser. Determined to be winners, both Natsu and Gajeel strike the Demons simultaneously and then proceed to overpower them with a barrage of attacks, much to Torafusa's shock. His surprise soon changes into fear as Natsu casts Crimson Lotus: Exploding Lightning Blade against Tempesta while Gajeel blasts Torafusa away with his Iron Shadow Dragon's Roar. However, still determined to win their bet, Natsu and Gajeel proceed punching each other, shocking both the Demons as well as Lucy who has been watching the battle.

Aftermath
The Dragon Slayers continue to argue, much to Lucy's frustration who scolds them for that. As Natsu and Gajeel each claim that they will be the first to beat their opponents, Torafusa interrupts the quarrel, claiming that they will be the ones to win and unleashes Tenchi Kaimei, filling the area with black water. Gajeel soon finds out that the water is poisonous and with Lucy, Juvia and Natsu already unconscious, he faces Torafusa alone.
