Nagisa Shiratori

Nagisa Shiratori is a main protagonist from Cho Kuse ni Nariso. 

Nagisa Shiratori is the heir to a judo training hall that has fallen on such hard times that their only pupils are animals from a nearby wildlife park. In a desperate bit to save her heritage, she reveals that she is going to go out into the world as an idol singer and find "strong men" to join her school. The first part of her plan succeeds beyond her wildest dreams: she is almost instantly elevated to the status of Japan's top idol despite an utter lack of anything even remotely resembling musical talent. Yet this dooms the second part of her plan, because her fame and schedule prevent her from finding the disciples she seeks.
