Being unable to look on in silence, Tanjiro intervenes to speak on behalf of Kotetsu, however Muichiro refuses to listen.

he'd withhold food and water from you
if you failed to meet his demands!
ومنع عنّي الطّعام والشّراب
!كلّما فشلت في الارتقاء لمتطلّباته
bestraft er mich mit
Wasser- und Nahrungsentzug!
no te da ni agua ni comida.
je ne peux ni boire ni manger,
une torture !

non mi dava cibo e acqua,
e senza battere ciglio!
Se não conseguisse cumprir os 
objetivos, nada de comida e água.
он безжалостно
оставит меня без еды и воды.
