No...? why are we assuming stuff that based on nothing? they didn't abandon anything, the story will slowly progress and connect, and the connections and the bulid up are already there, this always has been ZZZ story telling style, just like Kusuriya no Hitorigoto story telling style
And TOPS literally got thire own teaser, the leaders got introduced, and Youkai is with them too
And S3 teaser is meant to show Roscaelifer, the city, it's culture
And speaking of TOPS, Phoenix appeared in S3 teaser, and she's part of Krampus, and Krampus is part of TOPS
I've said this multiple times, you guys need to be patient, the story didn't even start yet, the chapters didn't release, wait to see story unfold
