YOU SAID:
Fire alone will save the clan
INTO JAPANESE
一人で火事が一族を救う
BACK INTO ENGLISH
Fire alone saves the family
INTO JAPANESE
火だけで家族を救う
BACK INTO ENGLISH
Save the family with fire alone
INTO JAPANESE
一人で火で家族を救う
BACK INTO ENGLISH
Save the family with fire alone
That didn't even make that much sense in English.
