Astor Inqerad

Astor Inqerad (白閃煉獄竜翔 （アシュトル・インケラード）, Ashutoru.Inkerādo, Flying White Flash Dragon from Purgatory) is the Extreme Magic of Kouen Ren's Djinn, Astaroth. When used, it creates a dragon made out of white flames, which comes from the Metal Vessel symbol. It incinerates everything within its path in an instant. Even after the attack ends, the flames of Astaroth are supposed to last for all eternity unless Kouen orders them to disappear or they got sucked by something from outside.
