@nutman451 my wording is probably wrong, I don't mean it to be a Important arc(it's not it's just fan service & small character development) what I mean was it's a breathing room arc, the arc suppose to down the tension to zero again, I mean yeah there is the iruma birthday & the shopping chapter but even in that chapter reader probably still remember the high tension before, this idol arc is supposed to zero out/nullify the tension entirely, and since the tension is already nullify with the Idol arc the next bomb the author drop would seem more exciting since the past few chapters was just some silly skit & pretty much the usual life. Also, I disagree with you on the Kerori character development was for the worse, In these past chapter Kerori got developed into an actual someone that has life outside of Iruma POV, it didn't super develop her but that peek into her life IMO is enough.
I do find it the arc not super interesting, but I disagree on antagonizing the arc
