First year student in Tokyo Denki University. Pro-active otaku, who's got a thing for both 2-D and 3-D girls. Talks quite a lot, and uses @ch (a spin-off of 2ch) terminology. Plenty of statements he makes could be taken as sexual harassment. He and Rintarou have known each other since high school. Usually turns down Rintarou's ridiculous requests as "annoying", but in truth gets them done in proper order. However, he trusts Rintarou as a friend. Has great confidence in his programming and hacking abilities (he doesn't mind being called a Super Hacker, but doesn't like it when people call him Super Haker). He's always in front of the computer.
Has the nickname "Daru" (ダル), abbreviated after his name.
