Ichiro and the others head to Osaka Bay to dismantle the bombs at the theme park where TBH announces that they're holding an Underground Division Rap Battle. The crews split into three groups to cover three areas, then assassins appear to block their way!
The more they fight, 
the stronger we will become.
.كلّما تقاتلوا، صرنا نحن أقوى
Mientras más luchen,
más fuertes nos harán.
Plus ils se battront,
et plus nous deviendrons forts.
Quanto mais lutarem,
mais fortes ficaremos.
Чем больше они баттлят с другими,
тем сильнее становимся мы.
