Fire Dragon King's Roar (炎竜王の咆哮 Enryūō no Hōkō) is a Fire Dragon Slayer Magic Spell.


The user produces a searing hot flame in their mouth before spewing it out in the direction they are facing. The unleashed flames engulf a large-scale area and, with their incredible heat, can not only scorch the earth beneath it but utterly vaporize it, leaving a U-shaped valley in its wake and taking out an entire battalion's worth of as much as exactly 973 soldiers.[1]
