Sasayaki

He once had only the purest of thoughts. As a graduate student he had dreams, aspirations, and a desire to learn all things archaeology. But all of that came to an end when his ideals and hopes collided with the harsh reality. His desire to get back at the women who demeaned him opened the door to the whispering devil that now keeps on stirring the darkness inside him. Meet the high school humiliation AVG, packed full of twisted madness! A literal hell on Earth--an all-girls school. Such a pity that, at the unwanted suggestion of a junior faculty member, he had to fill in for a professor there. Day after day, those pesky little bitches refuse to listen to anything that comes out of his mouth. But forget about the students; even the nagging teacher keeps on harassing him! No wonder the whisper in his head keeps asking for revenge. But will he succeed in fulfilling this burning desire, or will he die trying? Well, you never know until you try it. [Adapted from getchu]
