While watching the news, Takemichi Hanagaki discovers that his middle school girlfriend, Hinata Tachibana, has been killed. The only girlfriend he ever had was murdered by a notorious gang known as the Tokyo Manji Gang. Living in a shabby apartment with thin walls, he faces constant humiliation from his boss who is six years younger than him. To make matters worse, he is still a virgin. At his lowest point in life, he suddenly finds himself transported back twelve years to his middle school days! In order to save Hinata and transform his own life, which has been marked by running away, the hopeless part-timer Takemichi must aim to become the leader of Kanto's most dangerous delinquent gang.
