Kantoku's true nature is that of a small shard-metal gear box about the size of a two marbles side by side. The shard metal that makes up the box is as translusent as slightly tented glass, while the gears inside are all microscopic and made of magem. The shard metal bends light some but while Kantoku's body can hide itself mostly the high metal content in the frame of the gear box makes it impossible for him to totally hide the gear box. But from a distance or standing still... it's hard to see.

Current Body:  Shape shifting magem clockwork bird golem
The body is made 100% out of Magem, magem-metal, and magem and magem-megal gears this allows some abilities other golems could not normaly have.

Capabilities:
High speed flight Omni-drive capable of shield projection

Knife missile drone feathers (not every one of them, lol)

Forms:

Interaction mode
A humanoid bird-man like shape with arms and wings on it's back, fairly standard. Designed for interacting with humanoids and things built for humanoids.

Stealth mode
Looks like the typical clockwork bird... only well made out of magem stuff.

High speed flight mode
Similar to stealth mode only more compact, and aerodynamic.
