He runs the Computer Research Society, a club that operates out of a room right next to the SOS Brigade's space. Nobody really calls him anything but "Computer Society President"—his actual name is a mystery, though the first syllable is apparently "ya."
The guy's got a legitimate grudge against Haruhi. She blackmailed his entire club into handing over their best computer and letting her wire their clubroom for internet access. He hasn't gotten over it, and he regularly checks the SOS Brigade's website to see if they're actually using that stolen machine.Despite the rough treatment, the Computer Society is serious about what they do. The President and his four club members developed their own sci-fi strategy game called The Day of Sagittarius III (no, there's no Day of Sagittarius I or II—they just liked how the III sounded). When he challenged the SOS Brigade to a match later on, he was playing for keeps: four of his club's laptops on the line, hoping to finally get his original computer back. His club even rigged the competition in their favor.
It didn't matter. Yuki reprogrammed the entire game mid-match and the Brigade crushed them. The President walked away down four more laptops, but here's the thing—he was actually happy about it. He'd just discovered a genuine computer genius who might actually join his club. The light novels suggest he might be nursing a quiet crush on Yuki too, though he'd probably never admit it.
