Hanagaki Takemichi is a worthless part-time worker who's down in the dumps. One day, he learns that his girlfriend from junior high school, Tachibana Hinata, was killed from being a victim of the conflict between the Tokyo Manji Gang. Takemichi is shocked by the sudden news but goes about his daily life when he is suddenly pushed off the station platform onto the railroad tracks. He is prepared to die as he sees the train coming right for him, but the next thing he knows, he's reliving his life from 12 years ago.
If any third-year tries to mess with us, 
we just need to namedrop Masaru-kun.
إن حاول أيّ من تلاميذ السنة الثالثة العبث
.معنا، فما علينا سوى ذكر اسم ماسارو-كن
Hm?
Se qualcuno del terzo anno prova a darci problemi,
ci basta dire che conosciamo Masaru.
Se alguém no terceiro ano se meter
conosco, só dizer o nome do Masaru.
Если будут задирать девятиклассники,
просто напомним им о Масару.
