I'll be honest here - compared to most comments, I really lost the interest in this one over time. I still read it, but it felt like it was the strongest in its early chapters and then it just... whittled away? And it's not the issue with the format, I still love every chapter of Futaribeya, which is almost as long (longer by page count).
It's just that... all the tries to cram in some development felt really obvious and unnatural to me. Don't even know why, because it was pretty natural life events that "could" actually happen. Maybe Sakuma felt like a watching bystander as of late, even over the tries to give her her own plot? Maybe Wanko felt like she didn't ever change, because each her development was closed by the same celebration (which made it felt like the same old Wanko, even though the chapter was all about development)? I know these are partly stupid reasons, but it really made it felt like every advancement and development was crammed in, loudly announced and then it amounted to nothing... in the end they have a role as a seiyuu and a role as a writer, but didn't they do that at the start as well, just on smaller scale? Maybe the feeling of development it meant for them was somehow not transferred enough for me to understand it, dissolved by side events and side plots?
Don't know. But in the end, the later chapters were just a miss with me, sorry, Ikeda-sensei.
