Mikihisa Komaki, like Dojo, is twenty-seven-years-old, is a member of the Library Task Force, and is ranked Library Officer Second Class. He is typically seen smiling or laughing at his coworkers, especially concerning the conversations between Kasahara and Dojo. He is also one of the instructors in the task force. He often gives advice to Dojo or Kasahara in regards to the relationship between them, whether it be on a personal or professional level. He is partly responsible to Kasahara being drafted into the task force. Komaki smiles a lot and is pretty handsome, resulting in a lot of girls liking him. He once said that he will live a 'straight' life and would never lie about things, as shown in his refusal on participating with Iku's plan to deceive her parents that she is not working in the defense force.
