A spunky high school student girl named Ryoko and her friends form a special club that specializes in helping people and resolving issues for their classemates using some odd but working tactics to do the job. The club that they all work in is called Otogi Bank. Ryoko one day goes onto a mission and finds that she is in for something. During a fight, something happens that Ryoko will not soon forget, but the question is... what happened? She does not quite know, but she will be finding her way to that answer after seeing and hearing some things. Then, after all of it... she finds something important that will change her life, for once ... she will meet someone special. Someone special, she doesn't quite understand at first, but on the way, its just a mystery.
