|Occupation||SOL Technologies Security Manager|
After Akira got demoted, Kitamura replaced his position as SOL Technologies Security Manager. He is in charge of the project to create an army of AI Duelists to protect LINK VRAINS from hackers. Kitamura grew frustrated, as Playmaker defeated the prototype AI. He ordered the other AI to attack him, but his employees explained the other AI was defeated by Blue Angel. Kitamura declared he would fire his employees, but was even more shocked there were other people at the data bank, namely Ghost Girl and the chief of SOL Technologies, Akira. Kitamura watched as Akira confronted Playmaker, bringing up the accident involving SOL Technologies ten years ago as they dueled. Intrigued by what he was hearing, but realizing that this was sensitive information, he ordered his employees to send the footage to his office to record and to turn off all the monitors, threatening to fire them if they didn't, and went to his office and to watch the footage alone. As the duel progressed and Akira proceeded to reveal his and Aoi's past, Kitamura briefly wondered what he was talking about when he brought up the possibility of Aoi getting kidnapped and what SOL Technologies had to do with it.
Kitamura watched the two Duel, and was surprised to hear Playmaker was a victim of the Hanoi Project. Kitamura was excited Akira was close to defeating Playmaker and thought he'd be able to threaten the SOL Technologies' superiors, forcing them to promote him. However, Playmaker defeated Akira, causing Kitamura to go berserk and yell in frustration, all of which his subordinates heard outside his office. Kitamura, who retained his position, was shocked that an eclipse occurred in LINK VRAINS. Thinking this was a virus or a bug, he gave orders to his employees to stop that, else he'd fire them.
He announced to the media his AI army was made to defeat The Knights of Hanoi. He had his employees take control of the AI, and believed he would even earn a promotion. Despite a number of Knights of Hanoi were defeated, the employees started reporting that the AI army was losing. Kitamura was shocked, and saw two elite Knights of Hanoi have defeated his army.
