Ex-Gram

Ex-Gram was created by Kaoru Nagase by bestow to Francette, to defeat the Army of Arigo Empire . Kaoru gave a ceremonial after she got stab in the war and protecting Lord Roland.

Origin
As Kaoru estate of how was she able to create a sword?

This wasn't actually a sword. It was made of a special alloy one so tough it would it never break. The edge of the blade was sharpened on a molecular level, and it used the Bioelectricity of it's wielder as an energy source to vibrate the blade at incredibly high speed. In short it was a sort of "Vibro-blade."

But if you twisted hild you would find a Healing potion inside it was a container for a potion shaped to look like a sword.

Effect
The edge of the blade was sharpened to a fine point on a molecular level, and it used the bioelectricity of whoever gripped its hilt as an energy source to vibrate the blade at incredibly high speeds.

Variation
Sister Sword:


 * Just like with gram and ridill, Kaoru borrowed another name from one of the swords Sigurd had used. It was a legendary whose power had been split into four but the sharpness of its blade was more than of Legendary status, as Kaoru told them.
 * Exridill: similar to Exgram. Kaoru only lent the sword to Lord Roland for assisting it in battle. After the battle the sword was taken back by Kaoru.
 * Exhrotti: four swords similar to Exgram but without the ability to vibrate the blade at incredibly high speeds. The royal knight wielded the divine blade lent by Kaoru and fully given to them.
 * Exhovud: sword similar to Exgram but without the ability to vibrate the blade at incredibly high speeds. Given to Roland as he kept on bothering Kaoru to make him a sword.

Trivia

 * The name Ex-gram came up for naming the sword is the legendary sword Excaliber.
