I watched this anime film when I was young and would really like to watch it again, I will give you as much detail of the film as possible.
- The main character was a school girl who for some reason who really strong if she wore certain knickers (Not a hentai haha)
- It is set in a high school which was overrun by the students until the school hired a new principle who was really strong, he had a fight with the student and beat them all
- The main character had long blue hair, her bestfriend was a guy and her knickers were blue
- The principle was the villain, he ate fish bones, black hair and very big. When you first see him in the film, I think he is at the bus stop eating fish bones wearing a big coat and hat
- One of the scenes, the main characters bestfriend tries to fight the principle with a stick, he keeps hitting the stick at his pants (apparently the principle is stronger with these certain pants too, again not hentai) but for some reason everytime he hit one off, another one was there so he kept on doing it until there was a mountain of pants haha
- I watched this on video and before the year 2000, it was aged 15 or 18 but im sure 15
- I remember the main character was on the front of the case
- Another scene is when the principle enters a room and all the students try to ambush him but the principle beats them all
- The principle dies by falling off a lift fighting against the main character
That is all i can remember, hopefully this helps.
