Synopsis
Inside the temple, everyone hears the deafening roar of the beast concluding that it has been revived. Erza Scarlet, Lucy Heartfilia and Happy together inside the temple see the Moon Drip light and Titania guesses that the creature may not be fully revived yet. With this hope, they hurry to interrupt the ritual.

Natsu continues his battle against Zalty. The latter explains to Salamander his Arc of Time Magic properties. Natsu asks Zalty if he can actually use this Magic on humans to which Zalty replies not on all creature for instance, Deliora. The dragon slayer asks Zalty his true motives and, the latter reveals that he wants to manipulate Deliora. He says he wants power and Natsu says his power is his comrades. An enraged Natsu charges on Zalty and finally, he punches Zalty with his Fire Dragon's Iron Fist, sending his opponent flying.

At the top of the temple, Erza attacks Toby and stops the Moon Drip ritual. Toby tells the group that it is too late now, the ritual has been completed. Below, Deliora has been fully released from the ice case.

A bewildered Natsu tells Gray to help him take down the beast and Lyon crawls saying it is his duty to kill Deliora and surpass Ur. Gray however, says he surely won't be able to do it due to his current state. Lyon remembers how he found Ur; he asked for the strongest Mage and, then asked Ur to take him as her pupil. He also remembers being slapped by Ur as he asks is he not enough for the replacement of her late daughter to which Ur replies she never considered him as a replacement but a beloved pupil. Lyon struggles to get back on his feet, determined to defeat the evil creature but suddenly, Gray knocks him to the ground.

Gray adopts the Iced Shell stance and says it is the only way to stop Deliora now. Lyon says he will again melt the ice and, challenge the beast. Natsu however, does not share the same opinion and says he will defeat Deliora, and stands in the way of Gray. Natsu says he already told Gray not to use this spell before and that he will not give up. Surprisingly, the beast starts to crumble with everyone surprised. Lyon says that the Deliora was long dead due to the ice subverted Deliora. He also says that he is no match to Ur with Natsu commenting on the awesomeness of their teacher. Gray remembers Ur telling him she will seal his darkness and Gray cries, and expresses his gratitude to Ur.

The ice-water streams away in the sea where, Ur continues to live. She will always keep watch over her two disciples forever.

Aftermath
Team Natsu celebrates the completion of their S-Class mission. Erza however, interrupts the celebration saying the quest is not yet over. They still have to find out why the villagers were turned into demons which proves to be tough.
