Matsuzaki (松崎, まつざき) is the school's gym teacher and guidance counselor. Kusuo introduces him in terms of "good cop bad cop" and that he'd be the bad cop. He is feared and hated by the students. Kusuo thinks that Matsuzaki-sensei isn't that bad and is actually a good ally for weak willed students like him.
Matsuzaki always wears a PE jersey and carries a wooden sword with him in school. He sports a beard which is constantly being shaved.
Matsuzaki is serious and curious PE coach who absolutely follows the rules. He confiscated things that his students brought.
Like Nendo Riki, Matsuzaki is also an idiot when Riki tell that Takahashi has a hair root virus.
According to Kusuo, he would be independent ally to him.
He has a soft side when he doesn't mind of his student to take a job such as taking time to repair items he confiscated if damaged, when receiving a false love letter from a student he thought it inappropriate for a teacher to have that sort of relationship with students, but still waited for hours just so he could let them down gently.
Matsuzaki was first seen holding a clothing inspection on the students outside the school and then later getting into a fight with Kongou, a deliquent. He was then about to be beaten up by Kongou when Hatakeyama-sensei stepped in and defeated Kougou, saving him.
He later shows up checking Kusuo's classroom and started confiscating the unnecessary things students had brought to class. After leaving, it was shown how the students both feared him and hated him by constantly playing with his name. Later that day, Takahashi and his friends saw how Matsuzaki was complaining that "it was hard" and concluded that he was playing the game he recently confiscated from them. Takahashi, one of the victims who had brought a rare Gorillabbit, tagged along with his other two friends and thought of a way to get their revenge at Matsuzaki. Kusuo who had overheard this decided at first to ignore them but then his interest was piqued and went to take a look at how it will happen. The plan was to make Matsuzaki on the school for hours using the love letter that Takahashi himself made. Matsuzaki toook the bait and was standing in front of the school for nearly 2 hours. This made Kusuo feel the need to help him since he had been helped by Matsuzaki before. Kusuo transformed into a girl and went as the girl known as Kusuko. Takahashi and his friends was shocked to see a cute girl appearing since the letter was supposed to be a dummy and then thought there might be a coincidence to it. Matsuzaki then rejected Kusuko saying he shouldn't play favoritism towards his students so he can't answer her feelings. Kusuko then went on his way near where Takahashi and the others were hiding and Matsuzaki found them. They were about to ran away when Matsuzaki stopped them saying how he was trying to fix the Gorillabbit he tore and it was hard to sew. Realizing them were misunderstanding him, the three apologized to Matsuzaki and went home.
