>>3709014That's just one character that's part of a phrase. A colloquial translation of 「相変わらず良いニオイしやがる・・・グヘヘ」 would be something like "fuck yeah, smells good as ever... guhehe" and more literally "as usual, fucking smells good... guhehe". Tomoko is speaking in a crass/cool way like a character in manga.
