Harada is still struggling to overcome his amnesia. He tries his hand at a former pastime of his, plus reconnects with an old school chum in the hopes that this might trigger some memories.
No, they just like beating people up. 
They don't especially like boxing.
.لا، يحبّان ضرب النّاس فحسب
لا يحبّان الملاكمة بعينها
Nein, die verprügeln bloß gerne andere.
No, solo les gusta golpear a la gente.
No les apasiona el boxeo.
No, solo les gusta zurrar a la gente.
No es que se pirren por el boxeo.
Não, só gostam de bater nos outros,
não significa que gostam de boxe.
Да нет, бокс их не особо интересует. 
Они людей бить любят.
