Kagesuge Mishima

Mishima is the commander of Stea's operations at the North Pole (mostly research surrounding the Kaballah and the Angels). He has fused himself with his O-Parts. In his most recent appearances, he appears to have become disillusioned with Miko's dreams, and helped Jio and company free Ruby's body from her containment chamber, although it may have just been an exchange since he took the Legendary O-Part.
