Metal Magic

Metal Magic (Metaru Majikku) is a basic but versatile Caster-type Magic that allows you to manipulate any metal existing around the area, or simply generate metals with magical energy for offensive and defensive purposes, such as hardening your skin into various metals with magical energy, allowing the user to easily endure high-powered attacks while also empowering the damage you deal to your opponents. Also, your metals aren't limited to you using only things such as iron or steel, so you can use any metal from gold, silver and bronze to copper, aluminum, and platinum. It is used by Kinzoku Smith.
