Isn't him the guy with the Fox Mask?
Yes Yusuke is the guy with the fox mask. The inconsistency I'm pointing at is in the anime cutscene where we see the codenames on Sakura's phone(hacker squid girl) we can read Inari https://en.wikipedia.org/wiki/Inari_Ōkami. Which doesn't fit really with anyone but Yusuke yet in the promo art you can kind of make out "Fox" in the background of his face.
The rest of the codenames on the promo art line up with the ones we see on Sakua's phone.
But like I said the change might just be a design related reason or some some Japanese shenanigans where it's written Inari but you're supposed to read it as Fox(although it would be a bit weird since stuff like that is usually done with Kanji might just be I haven't read enough to encounter it on katakana) or who knows.
