Orange Fire

Orange Fire (オレンジファイア Orenji Faia) is a Fire Magic Spell.

Description
Stinky fire, created to deal with Natsu's flame eating abilities. The stench proved too much for Natsu due to his heightened sense of smell, causing him to think of Totomaru as having poor hygiene. In the anime, Totomaru stated that the scent came from a dirty mop submerged in expired milk.
