Lesser Dad!What's so soft?Becomests soft!Becomests soft!Softe sushi!
An untranslatable pun based on Rouxls' faux archaic speech and where the breaks between words are. He's saying "yawarakainari" which could be "becomests soft" (yawarakai nari) or "soft inari" (yawaraka inari), with inari here meaning the type of sushi.soft inarizushisoft inarizushi
