The instructor is mentioned by Abu in conversation with Li Wen. Abu recalls that if it weren't for Li Wen fixing the signal device on the practical training mecha, he would have been kicked out by the instructor. This shows that the instructor is strict and has the authority to expel students for poor performance. The instructor is not seen directly but influences the backstory, highlighting Li Wen's technical skill and the high stakes of practical training. The instructor's standards are high, and he would have terminated Abu without Li Wen's help.
