Each weapon had its energy, but usually, it couldn't be used, so the energy just increased the overall strength of the weapon and nothing more. However, if it was a weapon with a mind like Gladius or Vexa, they had their own energy that they could use if they wanted or give it to their owner to help them, it all depended on the situation.

Whoooooooooosh.

'Hahaha, normally my energy is always mixed with yours, but now I have a unique opportunity to show my pure energy!' Gladius exclaimed with an excited expression as large amounts of darkness emerged from the runes on his blade.

Previously Gladius had only a fraction of the power, so this was the first time he had used his energy since recovering and awakening his memory.
