The president of the North High School's Computer Research Society and victim of Haruhi Suzumiya's schemes.
Nothing is known about the Computer Research Society President's past, including his actual name. His club is right next door to the SOS Brigade, which led to Haruhi's desire to swipe one of their computers. She did so by placing the president's hand on Mikuru'sbreast and taking photos, then blackmailing him, to his shame. The president attempted to win back the computer by challenging the SOS Brigade to a match via a computer game the club created, but the attempt failed thanks to Yuki's efforts.
His involvement with the SOS Brigade unfortunately led him to be temporarily trapped in a strange spacial plane, from which he was freed by the SOS Brigade. He is unaware of this.
Passionate about computers and probably one of Yuki's secret admirers, he holds a grudge against Haruhi for the loss of not only the computer she blackmailed out of him, but the four laptops the SOS Brigade won because of his computer game wager.
