The Raikage

Weapon Name: Steel Magnolia
Type: Katana
Description: It helps me control lightning/electricity, as well as conduct it. I also use it to store electricity to release during a jutsu or a fight.
Advantages: My powers will not be as dependent on weather, as I will have a store of electricity with me as long as I have the sword. Few people will be able to use it besides me, as anyone who holds it will get shocked. (This is an advantage and a disadvantage at the same time.)
Disadvantages: Those who come into contact with it get shocked, including the user herself. During humid or wet weather, it is harder to control the release of electricity, and I may use the wrong technique, or fail to use one at all. When the blade is broken, all of the electricity it has stored is released, and EVERYONE at the place of the fight will be severely shocked and burned.
