From the Tenchu game series. I actually thought it was an anime at first. Not familiar with it at all. I feel like I've heard of the series before, but it would have been in passing. Regardless, it was still a really fun project to take on.

Legs were from a Hand Ninja, completely resculpted. Boots, knees, upper legs, and feet. Left hand from Cyclops. Sculpted up the chainmail, bracers, belt, full torso, and strap for the sheath. Sword and sheath were from Marauder. Head was from a BossFight male blank with the mask and hair sculpted on. Full repaint, and all done!
