Am I the only one who notices that the writing is no longer consistent after volume 5 Y2

The current volumes include random developments in the story so suddenly that I would not be surprised if anything happens in the next volumes, and there is no longer consistency in writing the characters, The characters fell out of her personality after the 5 volume

I know that Kinusaga has a history of spoiling his novels by resurrecting in the middle of the story, and I expected cote to be different considering that it is ln and not vn, which he used to work on.
