It is a lecturer of the Great Nature University, and also the advisor of the “Discipline Committee Enforcement Squad.” Usually it is a very gentle model lecturer that is endeared and covected by the students. However, once one is found violating the School Rules, it will become a discipline demon and enforce the rules with a demonic look on its face. His catchphrase is "I am not a demon. First time, you'll get a warning. Second time, you'll get a fist. Third time--" However, because most violators learned their lesson after being caught the second time, nobody knows what will happen on the third time. It is reccommended if you don't want to turn into a hole in the wall, you live your student life moderately in accordance of the campus regulations.
