So the end is finally here
Honestly while there were a lot of plotlines the mangaka probably wanted to explore they still managed to do a good job with the time they had
Duty bound ogre slayer descendants who cant change their position and outlook
Ogres who were locked away far too long to even go back to the days of old
and Monsters who never change
All the supernatural in this manga are still playing their old roles even in modern day
and then we have Naori who can probably see the complete picture if she calms down more
Relationship labels are just a means to an end here
it doesn't really matter what you think the characters identify as ultimately it can either end with them dating officially or just doubling down on the "relationship that is special only to them"
I personally just want to see them 2 together forever
