Kuro no Onna Kyoushi (2012)

Takakura Yuko is an ordinary chemistry teacher at a famous government-run preparatory school by day. But at night, she is a super teacher who solves a variety of difficult problems rampant on the school grounds that require more than sound arguments, from bullying to illicit sexual relations, marijuana and hallucinatory herbs. Her approach is “an eye for an eye”. She is willing to break the law in order to solve issues, anddemand money from the people who seek help along with the classics teacher, Uchida Sumire and the art teacher, Fujii Aya whom she gets on famously with despite their different personalities and interests.
