I can't remember who made it, but I think the dude's name starts with "Ficticious" and ends with "Animation".
XD! Okay but this is based off of ~GhosttheHedgehog12's [link] Slim MKII Sword. ^^ Btw, Happy birthday, Ghost!! Go wish him a happy birthday guys!! The Mecha Shadow model is by ~FicticiousAnimation. [link]
This download comes with four models. It has the red and bue PMX files, and the red and blue X files. If you know how to use accessories, I recommend using the X files. Trust me, trying to make a PMD move around perfectly with a hand is not fun. XD!
Made by FicticiousAnimation in Blender 2.63. Everything on this is custom.
You may edit this however you see fit. ^^ You must credit ~FicticiousAnimation though and you can definitely redistribute.
