Natsuhiko Koyama, is a student in Class 3-A in Kunugigaoka Junior High School and one of the Big Five. He is also the president of the Biology Club. Koyama is not different from the rest of the Five Virtuosos in terms of behavior and temperament. He, like most other people in the main campus, looks down on the E class and is constantly frustrated when beaten by them. He is an extremely intelligent person, and excels in science, despite being constantly beat out for the top spots. Memorization: He claims to have memorized every chemical formula in preparation for Kunugigaoka's exams. His abilities are lampshaded further in Koro-Q, where he claims to have memorized every monster listed in the monster encyclopedia.
Assassination Classroom
When a mysterious creature chops the moon down to a permanent crescent, the students of class 3-E of Kunugigaoka Middle School find themselves confronted with an enormous task: assassinate the creature responsible for the disaster before Earth suffers a similar fate. However, the monster, dubbed Koro-sensei (the indestructible teacher), is able to fly at speeds of up to Mach 20, which he demonstrates freely, leaving any attempt to subdue him in his extraterrestrial dust. Furthermore, the misfits of 3-E soon find that the strange, tentacled beast is more than just indomitable—he is the best teacher they have ever had! Adapted from the humorous hit manga by Yuusei Matsui, Ansatsu Kyoushitsu tells the story of these junior high pupils as they polish their assassination skills and grow in order to stand strong against the oppressive school system, their own life problems, and one day, Koro-sensei.
