Higuchi Yuuya is a nineteen-year-old hacker/detective who works for the police. He played an important role in the HAL arc. Although he is far-sighted, he only wears his glasses when using the computer, letting them rest on his forehead the rest of the time. He considers himself responsible for his parents' deaths, because he used his hacking skills to shut down the online video game they were addicted to, which led to them killing themselves. During the HAL arc, he was infected with the Electronic Drug to become one of HAL's guardians, although the infection was only half complete, because he was wearing glasses at the time, with polarized lenses specially made to protect himself from it.

After the HAL arc, he was forced to watch shows on how to be polite drugged with the anti-virus for the Electronic Drug. Though, he still remembered how to make the Electronic Drug, and he comically used it on a supervisor who was overbearing on him, but this was found out and he was subjected to another session with the anti-virus, though for twice as long, to forget how to make it.
