[Kazuyoshi Usui's](https://anilist.co/character/17246/Kazuyoshi-Usui) younger brother.

Masafumi is a year younger than his brother. He is brilliant with computers, and possesses a very scientific mind. He created the speech synthesis software that Switch always uses.

 ~!He is the original source of the "Switch" nickname. The reason for his nickname was because he was called Usui-chii by his friends and it sounded like "Switch". Thus, it became his nickname.!~ 

 ~!He was killed by [Yukino](https://anilist.co/character/42890/Yukino-Hirai), who mistakenly believed that he and [Sawa](https://anilist.co/character/42408/Sawa-Yamauchi) were dating.!~

At Kaimei High School, the Living Assistance Club (aka the Sket Brigade) was organized to help students with problems big or small. Most of the time, though, they hang out in their club room, bored, with only a few trivial problems floating in every once in a while. In spite of this, they still throw all their energy into solving these worries.
