In this cavern, they discover the frozen demon Deliora along with three Mages: Sherry Blendy, Yuka Suzuki and Toby. Erza tells Gray to go while she, Lucy, and Happy hold them off. As shock turns to rage among the group, Erza demands to know what happened. After the first wave from enemy, Mavis sent a squad into southern front.
Also, he has a disturbing habit of unconsciously removing his clothes (including underwear) at inappropriate moments. 1.) Natsu Dragneel vs. Gray Fullbuster is a fight fought between the Fairy Tail Mages Natsu Dragneel and Gray Fullbuster. After the mission on Galuna Island, he gets a scar on his forehead above his left eye that is partially covered by his hair. Natsu further explains that the Mage was holding a skull-shaped flute, which Lucy recognizes as the Lullaby, a mass-murder curse that kills anyone who listens to its music. Gray realizes the unmistakable roar comes from the demon Deliora and decides to finish it off himself using Iced Shell. When Gray heard of Deliora's current location, he decided to challenge it, ignoring Ur and Lyon's warnings. Gray was present when Erza entered the guild, having been told by Cana that that day would be lucky for him, though he regarded it as one of the worst days of his life, having lost his wallet and fallen in ditches. Gray thinks it is an uncomfortable moment being alone with Erza since she just stands in armor and watches him. His pants are torn and patched and his arms and legs are wrapped in bandages.
Because of this, Gray challenges her multiple times but always loses, Wakaba teases Gray that he has a crush on her because he always picks a fight and became very persistent of it, angering him even more as he states that he can't accept her as his comrade. 400 years ago, Natsu was born as the younger brother of Zeref, however, he died at a young age alongside their parents, courtesy of a Dragon attack. At various points in time, he has challenged Erza, Laxus, Mirajane, and even Gildarts (in short, all of Fairy Tail's current S-Class Mages), to fight him, albeit, he was beaten every single time. She explained to Gray that Iced Shell was the only thing that would beat Deliora, and was surprised to know that Lyon had tried to do what she planned. Before meeting Natsu, it was revealed that some of their guildmates teased Gray for paying so much attention to Erza (as he liked to pick fights with her), and some even joked that Gray might've had a crush on her.
He suggested that they all eat it together, but was astonished when Natsu claimed the egg to be a dragon's egg as the marks on it were akin to those made by a dragon's claw. Lyon threatens to repeat the ritual again if he uses the spell. He adds that when morning comes, they return to their human forms, but there are those that are unfortunate and lose their minds. They are unknowingly accompanied by Juvia, who is stalking them. Jellal had been possessed by what he claimed to be the spirit of Zeref, and decided that the only way for them to attain true freedom was to complete the Tower of Heaven and revive Zeref. Following the one-time use of Igneel's power, the tattoo disappears and Natsu abandons the bandages. Replying that he had been listening to Juvia and Lyon, Erza tells him that he must have noticed Juvia's feelings for him by now. It is unclear if Erza has feelings for Gray as well, but she stops him from fighting and possibly hurting himself during the Phantom Lord battle because she believed there was no hope of winning. Gray Fullbuster(グレイ・フルバスター Gurei Furubasutā) is a Mage of the Fairy Tail Guild, wherein he is a member of Team Natsu. Gray's most prominent feature is his spiky black-colored hair. Gray listens as Invel reveals the true story of Zeref's demons and how Natsu is the strongest of them all as well as being Zeref's younger brother. Around this time, Fairy Tail's master Makarov brought Erza to see Porlyusica, who gave her an artificial eye to replace the one she lost. Gray comes to Happy's rescue just as another attack comes, and shouts at everyone that they have to rescue Erza no matter what because if they don't, they're going to lose Erza to Jellal, who will use her as a sacrifice for Zeref.
