Lt. Col. Kojima is an EFF officer in charge of the Federation outpost in Asia investigating Ginias Sahalin's nearby base. He is a subordinate to Captain Isan Ryer. He is the 08th Mobile Suit Team's and their fellow squad's base commander. He is a calm and quiet person, content with being outside in the jungle rather than an air conditioned space colony. He turns against Shiro when it appears that Shiro is betraying the Federation but gives Shiro a mission to reestablish himself and trusts him after they succeed in finding and attacking the Shuttering Mountain Base. He cares for his soldiers, being upset with his superior officer Ryer for the way he treats them.
