Guys, the Eievui in the poster was for the broadcast segments that are shown after the episode. Please don't go on unnecessary tangents over things that you don't pay close attention to because chances are, you might not have the slightest clue what you're talking about until actual hints are revealed. Nothing has been hinted yet at whether he'll actually catch this Eievui, and it's already appeared in the series.

If it does appear in the main episodes themselves, then yes, you might have a clue...but nothing's been confirmed about that yet either.
