Class 3-3 is a class at Yamaku Academy comprised of third year students. It is the class Hisao joins upon transferring. The class is taught by the science teacher Akio Mutou.

Trivia
The first time Hisao enters the class and takes a quick peak at his new classmates, he mentions that there is a girl who seems to be missing the thumb of her right hand, but none of the descriptions mentioned above match this.
Out of the main girls, Hisao is never mentioned to socialize with his other classmates, just occasional greetings. The only exception is Miki Miura, whom he seems to befriend a bit during Hanako's Route. For some of them, he admits to never have crossed a single word with them, just like the case with Takashi Maeda, who he sees in the Art Club and recognizes as a member of his class, but doesn't even mention his name.
