The new deca chapter is so good I don't know where to start.
I especially like how they treat Momoi as someone who acts as the leader of the group while still doing her antics.

You don't have to read the story, current event is just: spend AP > buy items.
Personally you should only read the story once you actually caught up.

To add to this, ch1ep1-12 of deca should be done between ch1 and ch2 of vol 2, the rest of the deca chapter/volume is canonically after vol F.
