Tristan is a minor character in Artificial Iridescence. He was Ava's superior at AppSir, Inc. While Ava was working on AIVA, she felt she needed AppSir resources to continue the project. So, she went on a date with Tristan and developed feelings for him. Not only did this interaction allow the AIVA project to continue, it also led Ava to cheat on her husband, Clint, by having an affair with Tristan. He also makes a brief appearance in HopBound, perhaps as a manager over interns like Mayumi. Little else is known of this mysterious AppSir manager.
