A kind of devil race. Their entire body is covered in a metal shell, similar to an insectoid's exoskeleton. Basic characteristic of Metal Midians. This is both their main weapon and personal armor.

Aside from the Metallic Group of Midians, there seems to exist Uncertain Group (不定系) and Bird Group (鳥類系).

Since it symbolizes the Midian, there are some differences between individuals and it’s something each one of them holds great pride in. 


First mentioned in Day 157.
