Weapon: Two Swords.
Name:Akuma and Tenshi
Ability: The two swords are twins, an angel and a devil. The Devil sword, Akuma is made out of red and Black, the color of hell. It's power is it's strength, it strengthens Rai's strength and power, but it's true power its cursed. The Angel Sword, Tenshi, is made out of red and white, the color of heaven. It is fast and good to kill the death, it cannot harm human. If the two combined the user will suffer from too much use of power and may go wild, it is never a good thing to keep them together.
