Akira Shindo has been transferred to Fuga High School where she is almost raped by a group of young thugs. She meets Mahiru Suruga, a mysterious but beautiful girl with both arms in bandages. Mahiru is aloof and cold. Her motto is, "I will neither rely on others nor have anything to do with others." The two girls get caught up in a series of incidents at school and Mahiru, a strong fighter, always manages to sort them out. Mahiru starts to soften up, as she becomes friends with Akira, who loves to stick her nose into other people's business.
Mahiru's school life is turned upside-down as many people approach her. Kaede is a high school student training as a swordmaster under a senile old man, who turns out to be a real pervert and a fake. Mahiru's father also comes into the story and things get chaotic.
One day, Satoru Tsunami, a high school student and an aspiring reporter starts following Mahiru. He deeply respects Mahiru and considers her the strongest high school student and a rebel against adults. Why is Mahiru so strong? Satoru tries to find out her secret. Why has Mahiru shut herself out? What is going on inside Mahiru's mind?
Peridot is a very interesting manga, besides the fact that it isn't highly publicized. It is about the mysterious, Mahiru, who believes in not putting any more effort than needed into the things she does, or getting involved with anyone or anything that doesn't personally concern herself. Her viewpoints slowly change as she recollects her past while teaming up with two other (hot) high school girls; Akira and Kaede as they encounter scandals, and fight off bands of delinquents in and out of their school. The story line is split up into many different short stories, which follow the main characters as they
journey through their lives trying to make them a little less boring and pass the time between classes (which they don't attend ^^). The stories also introduce all of the characters within the plot, while revealing a little bit more about the mysterious Mahiru and her past as the story moves along. Mahiru and her crew go through their glory days of high school fighting off pervy old men, wanna be gangsters, delinquents, and people who just can't seem to grasp the concept that they will never win. Mahiru's group tries desperately (excluding Mahiru..) to shape their dull lives into ones filled with excitement everyday. The story is filled with many intense and high quality fighting scenes, which can be seen as early as the first chapter when the main character, Mahiru beats a group delinquents senseless after they tried to rape Akira the previous night. Anyone who loves reading Seinens about girls duking it out in martial arts and beating each other up (with some ecchi of course ^^) should most certainly give this read a shot.
