I actually liked Agravity's chapter this week, a good bit better than the first, if not just because they've pretty much entirely moved away from the initial premise that seemed so off-putting to people. That being said, I do expect the mysterious being character is supposed to be some pseudo-antagonist, if not just in place to create at least some sense of conflict between four characters who normally get along well.
It also seems like it could be trying to foreshadow some space travel or at least interactions with other beings at some point, so we'll see.
P.S. the Yozakura Family hate hurts. I understand you see it as directionless because it's clearly supposed to be a romantic comedy, not a 250 chapter an arc battle series, but come on. Any one chapter singled out on its own isn't bad in my opinion, and as a whole, it's almost a good thing he isn't trying to use the entire family of characters every chapter. That would likely make each one even more shallow than if they didn't appear at all.
Also, I've been pretty keen on Mitama since the beginning, but chapter 6 I believe it was really got it going for me, and it has stayed consistently good, making it one of my earlier reads each week after CSM, BC, MHA, Yozakura, and One Piece.
