DEBUG BUILD! Also, it says all teachers went through extensive self defense training after an incident in 1989 (if you listen to the mysterious tapes you'd actually figure what that incident was). We can therefore assume that if you play in 1980's mode (if and when it becomes available) it would actually be easier to attack teachers.

Anyway Yanderedev's stated that in the future they will not be invincible, just very difficult to defeat. You'd probably have to max-out your physical training and/or be in the martial arts club.
