a concept thought of Lupin's armor and gauntlet. As a knight he'd have to be well equipped.
Before the 'blight' covered his whole right arm, his set was more symmetrical, but since the growth on his arm was hard and durable it was redundant.

I borrowed a few traits here and there from the Ar Tonelico series. Not sure if I'm going to keep it.
I guess it's an alternate reff sheet, including his mutating right arm.
