Fairy Tail

After retreating from their first clash with Phantom Lord, the members of Fairy Tail try to formulate a counterattack while their Master is being treated by his friend, Porlyusica. However, Phantom Lord decides to bring the war to Fairy Tail when their Super Mage Giant Phantom MK II machine arrives in Magnolia and begins to attack the guild with the Magical Convergent Cannon: Jupiter. The guild manages to survive the attack when Erza blocks the blast, though she loses consciousness from extreme magical exertion, leaving her guildmates to fight the rival guild as they charge the cannon to attack with Jupiter once more.
