Fire Magic: Spiral Flame 「炎魔法『螺旋焔』 Honō Mahō "Rasen Homura"」 is a Fire Magic spell.
With an open grimoire, the user generates flames from the palm of his hands. The flames come out in a spiraling motion, which creates a tornado-shaped blast of flames. In order to use it against his targets, the user simply holds his arms in the targets' directions. The flame's intensity is enough to incinerate completely anything in its path.
