YOU SAID:
I will eat your face now
INTO JAPANESE
今からあなたの顔を食べます
BACK INTO ENGLISH
I will eat your face from now on
INTO JAPANESE
これからあなたの顔を食べます
BACK INTO ENGLISH
I'm going to eat your face
INTO JAPANESE
私はあなたの顔を食べるつもりです
BACK INTO ENGLISH
I'm going to eat your face
That didn't even make that much sense in English.
