I speak for us all, when I say... "AHHHHHHHHGGGGHHHHHHHHH!"
I guess the post-haniel fame arc is not getting resolved. Cosplay is just a hobby. With your hubby? My hope for the next chapter is a time skip montage of all the things they do together on their bucket lists, then a Hina Doll Wedding.
This was always a "Learn how to be in a relationship with the lessons of cosplay" story. Each cosplay represented a specific theme, and Waka/Mari grew a little bit with each lesson. Slippery girls was about sacrificing yourself for others, and making sure to communicate. Black Lobelia was about dealing with Jealousy. Veronica was about setting boundaries. Succubus was about restraint and temptation. Arisa/Bunny girl was about getting help when you make mistakes. Rei/Council Host was about how asking for help is not a burden, and learning to love yourself. Coffin about examining and challenging your fears. And Haniel topped it off with a story about taking a risk for love, even when your love seems deadly and impossible.
I liked how each cosplay had a story within the story that mirrored those themes. I'm sad that Fukuda didn't want to tell story about "Now that we're in a relationship, how do we make it work?" But I think I'm ultimately ok with it ending here. We got a lot of great arcs. Especially Rei and Haniel.
I also think it's likely that Fukuda self-axed. Based on the inconsistent release schedule, I expect she was burning out, had health problems, or was running out of ideas/motivation. Ya did good work, Fukuda-Sensei.
