He's made to look like samurai looking character. I were out of inspiration a long moment so in between I made a challenge for myself to build a moc from limited parts and I chose Lumi and Hamara. This guy is the result and I have no story for him =[
For start he's got 3 weapons: a double-edged blade and his left arm is a beam cannon with a stabbing spike added to it.
Luha is fairly unique case in my collection 1. for his custom thighs, which are not the usual hip and shoulder connectors. 2. his armor holds pads hanging over legs and piraka feet pad over left arm.
