Haruna Kojima

Originally a mid-level manager (Kimura Takuya) with a promising future in a big corporation and loved by his subordinates, the life of this elite employee changes dramatically one day. Having for some reason attracted the attention of the senior management, he is framed for a crime which he knows nothing of and forced out of the workplace. Even after that, he is assailed by a series of surprises and in one day, he loses his house, wealth and handphone until he is without a cent to his name. At his wits end, he comes to a park where he encounters two children. Learning from them how to survive even if he does not have money, he somehow weathers this crisis and discovers the truly important and priceless things in life. The good thing about him is that his carefree personality amazingly does not shift. It is not resentment and bitterness that become his driving force, but the love and help of the people he meets that enables him to keep go forward step by step.

Two transfer students, Atsuko Maeda and Onizuka Daruma came at the all-girls school Majisuka Gakuen. In this school violence and fighting are common among the Yankee students. Noisy and trouble maker Daruma made a fuss as soon as she entered the school, win in her first fight but then was beaten easily by another gang shortly after. In contrary to Daruma's bold-but-powerless attitude, Maeda who is truthfully a strong girl despite of her silent nature found Daruma is beaten by Team Hormon before her. The word "Majisuka?" (means are you serious?) instantly awaken her true nature and made her won the battle against Daruma's attackers easily, thus made a big fuss at the school and the news even reached the strongest fighting group, Rappapa. Afterwards, Daruma acknowledged Maeda as her boss and as a result the friendship between the two girls began to grow along with their fights with fellow students at their school.
