PSImply Terrifying! Matsuzaki-sensei is the thirty-seventh chapter of Volume 4 of The Disastrous Life of Saiki K (Saiki Kusuo no Sai-nan) published in the 2nd of May 2013.
Matsuzaki was checking class 3 classroom and started confiscating the unnecessary things the students brought to class. After leaving, students mocker him and were constantly playing with his name. Later that day, Takahashi, Jaga and Shuuji stalked Matsuki and saw how the latter was having trouble with something and the three thought 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 took 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 fake 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 used his powers to make Matsuzaki find the three. 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 that they had misunderstood him, the three apologized to Matsuzaki and went home.
