You all remember my shinning white blade, Kamiakari (Divine Light), right? Well now meet its opposite, Kuragari-akuma (Dark-Devil). Its size and power matches Kamiakari but it runs in the opposite direction. While Kamiakari is made of Holy Matter Metal Kuragari-akuma is made of Hell Matter Metal.
Nope, the whole thing is done in my 3D program. The glow is created by shining a seris of lights on a pane of glass behind the blade. Not all of the lights are of the same color thus varing the color of the glow a bit.
