Kitamura

He is the former boss of Akira Zaizen at SOL Technologies.
Kitamura appears to be a control freak who reacts to everything in a comical manner. This is seen many times when he was observing Playmaker and Blue Angel's duel against the prototype AI duelists. He is also shown to be harsh to his subordinates as he threatens to fire them or cut their salaries by 50% if they disobey him. Despite this, most of his subordinates don't fear him much.
