Summary
Kazuyoshi Usui, known by his alias Switch, serves as the intellectual backbone and secretary for the Sket Dan. Although he frequently denies it, he is an otaku with encyclopedic knowledge of every student at Kaimei High School. While he projects a serious demeanor, his behavior often reveals a more playful side. Usui holds a firm belief in science, a conviction that fuels his rivalry with the occult enthusiast Yuuki Reiko. A distinctive trait of his is that he communicates exclusively through a computer, a quirk likely stemming from psychological trauma.
