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.
Let's say every time my fist meets 
your face, it's worth a hundred yen.
.لنقل أنّ كل مرة تلامس فيها قبضتي وجهك تساوي 100 ين
Ein Faustschlag ist 100 Yen wert.
Digamos que cada puñetazo
vale 100 yenes.
Digamos que cada puñetazo
vale 100 yenes.
Un poing dans ta gueule
pour 100 yens.
Diciamo che ogni pugno in faccia vale 100 yen.
Digamos que meu soco na sua cara
vale por 100 ienes.
Каждый удар в лицо будет стоить сто иен.
