|Devil King Sword|
Devil King Sword (魔王剣 Maoken) The Devil King Sword is a fiendish weapon of incredible power forged by Kaguya and is the evil counterpart of the Supreme King Sword. It looks like a huge, double-edged longsword with a black blade and white borders. The handle is black and rectangular, and with a white tip. The hilt itself is composed by a round body shaped like a fiendish head (with the open mouth serving as a power gauge) and two horn-shaped arms protunding to the sides and adorned by what seems to be black fur. The blade of the weapon is slightly larger at the bottom and sports a hook near the hilt. This blade can turn the evil spirit of the user into energy blasts capable of erasing all life from the Earth. When fully unleashed the blade turns into black energy.
According to their power gauge, It has three attack forms:
the Crescent Slash (weakest attack)
the Half-Moon Slash
the Full-Moon Slash (strongest attack) which has the power to destroy one planet in an instant.
