Magic and Abilities
Fire Dragon Slayer Magic (炎の滅竜魔法 Honō no Metsuryū Mahō) is a type of Dragon Slayer Magic that grants the user various characteristics typical of a Fire Dragon: lungs capable of spewing flames, scales that grant protection against fire, and nails covered in flames. Consequently, Fire Dragon Slayer Magic allows the user to produce and control fire from any part of their body, which can be used both in melee and as a ranged form of offense

In addition, the user can consume external sources of fire to restore their body to a healthy state and regain their reserves of strength, something that also makes them immune to most types of fire. However, the user can’t eat their own flames, or things set on fire by them, to reinvigorate themselves.
