Height 164 cm (5'5") First-year student at Tokyo Denki University. Pro-active otaku, who's got a thing for both 2-D and 3-D girls. Plenty of statements he makes could be taken as sexual harassment. He and Rintarou have known each other since high school. He usually dismissed Rintarou's ridiculous requests as "annoying", but actually completes them well, and 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.
