chitocerium is Good Smile Company's original plastic model-kit line, a build-it-yourself series of mechanical girl figures set in the line's own science-fiction world rather than a licensed property. The kits assemble into poseable, armored characters from the line's invented cast, GSC's bid in the buildable bishoujo-kit space its rivals helped open. The result sits between a figure and a model, a character a builder finishes by hand.
