In the second series, known as Mission Two, there was a character named Touma. He was similar to Kei and Yuri in that he was a trouble consultant, but his specialty was computers and computer programs. Physically, he resembled an average computer geek, with glasses and a tall, slender build. Despite being easily distracted by minor details, which often resulted in him getting beaten up by Kei and Yuri, Touma had little experience with dating. One of the most memorable moments in the series came from his lack of romantic knowledge.
Touma's computer expertise was nearly unparalleled. As a college student, he wrote the code for Silica 2000, the mainframe of World's World's chief. For this accomplishment, he received an "A." However, when Silica 2000 was infected by a virus, Touma was called upon to eradicate it. Due to the danger posed by the creator of the virus, Kei and Yuri joined him on the mission. They stayed behind while Touma isolated the computer from the Joint Artificial Intelligence Criminal, or J.A.I.C.
