Here is the list and identification of the weaponry each person possesses. If you want a specifically enhanced or modified weapon contact preferably Syutaku who will legally craft you the weapon of choice as long as the attributes are not too extreme.

Demonic Howling Sword: Held by ShiDo Kayumi, this rare sword was found within the Caves of Darkness, where ShiDo had to fight off a lesser demon with his own specific genre of magical abilities and manifested elements. This sword is said to have been made from a variety of synthetics which could very well possess the soul of the lesser demon which was defeated. Its true supernal power is still under observation. The blade has the ability to absorb properties of a variety of energies and magic and/or convert such into the opposite of one's true purpose.

Garyoutensei: A weapon Constructed of Melee alloys that have elemental prowess that may be summoned through Syutaku. The elements of either Fire, Wind, or Electricity may be used through this sword when summoned…when used enough energy the power of all three elements may be used in complete harmony to inflict major damage.
