He is an old gentleman who brought up Walter and is his manager. He is actually a military staff who has a close connection in the robot development ministry of the empire, and procures the robot arms suitable for the concept.

Their major antagonist is the flamboyant and thoroughly incompetent Walter, and the villains that follow him are often similarly humorous. <br><br>
