I'm happy because Yukko is happy.
Not seeing Mikane nor the Sea Woman in this Epilogue is actually kinda fitting.
Not happy because Yukko is still hung up on Mikane and he doesn't deserve her. And Yujin is too good of a guy to get done like that.
This just feels like the author was trying to put of a "big message" about moving on or growing out of a small town but couldn't quite pull it off. (I think it was a story of Mikane falling in love/infatuation with a single mother. Dealing with her and her kid.) Also just never addressing the carnivores.
But, Happy for Chi-chan finally deciding to stop giving the Prof a choice in the matter of he gets to be happy or not. She hate his dad so this is like daddy-issues-ception but w/e. Plus more Mai-chan & Rei-kun.
So I'd give this a B- as a final chapter - we get more than just the textual wrap up at the wedding, get to see Yuukko's relationship progress, her family's restaurant continue. But the title character's wrap up completely left out.
But the whole ending is like a C-, maybe a D.
