In a flashback, an eight-year-old Gray is found by Ur and Lyon as the sole survivor of one of Deliora's attacks. Seeking revenge against Deliora for killing his family, Gray becomes Ur's student in order to learn magic to defeat it. When Deliora reappears, Gray recklessly attempts to fight the demon and is easily overpowered. Ur arrives and casts the forbidden spell Iced Shell, which transforms her body into the ice that freezes Deliora. Although Ur explains that she will remain alive in this form, she has Gray inform Lyon that she has died so he will not waste his life trying to return her to normal, which sparks Lyon's resentment towards Gray. Back in the present, Gray engages Lyon again and prepares to use Iced Shell on his rival.
