Overseeing the Teiai corporate Twitter exposes Tonegawa to an account that seems to exist solely to hate on his company, triggering the middle manager's combative instincts. Meanwhile, Ootsuki's underground gambling games hit a snag when a rival foreman begins running his own entertainment scheme.
The underground prison. 
The absolute bottom of the barrel.
.سجن تحت الأرض 
.أسفل القاع
Das Untergrundgefängnis
tief unter der Erde …
La prisión subterránea.
Lo peor de lo peor.
La prisión subterránea.
Lo peor de lo peor.
Aux tréfonds de l’enfer,
au fond du fond !
La prigione sotterranea.
Il proverbiale fondo del barile.
A prisão subterrânea!
O fundo do poço!
Подземная тюрьма. 
Ниже опускаться некуда.
