Joshi gakuen: Warui asobi

Transfer student Henmi Ryoko enters a girls school and gets into a fight with the reigning girls-gang, attempting to become their new leader. Fitting to the english title "Dangerous Games" different challenges arise within the girlgang, they have connections to small-time yakuza and start a war against the school teachers.

The film is unique in regards to its main character the mysteriously gazing Ryoko which has a strong sense of duty but is also partly psychopath. She somehow resembles those female revenge characters like "Sasori Scorpion" but takes revenge not for herself but for others.

A nice movie in the tradition of school delinquent stories!
