Mitaka Arima, a great breaststuff who continues to be imprisoned by classmates of psychopaths

The students who attend the school in Tokyo are gentle and serious students. However, there was a problem with such 'mitaka.' It is that it is accompanied by the "Tochigi" of a bad student who is the son of the president of the school attending. Since Tochigi has a psychopathic aspect and does not know what he is thinking, "Mitaka" lived every day reluctantly to run away. A tragic, big-boobed girl who is constantly being deceived by incompetent crimes at home that has become disorderly. No. P for the Elderly
