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!
It's a no-holds-barred, 
last-man-standing battle.
.إنّها معركة بدون قيود، يفوز فيها آخر من يتبقّى واقفًا
Das heißt, alles ist erlaubt
und nur der Beste gewinnt.
Es donde todo se vale
y solo uno sobrevive.
Es un todos contra todos sin normas.
È uno scontro senza esclusione di colpi
in cui resta un solo vincitore.
É uma batalha que vale tudo,
até só sobrar um.
В ней всё можно,
она идёт до последнего выжившего.
