JJK at least had a narrative that was cohesive up untill the sister school fights, after that most the story happens off Screen, and is then added back in through exposition, which is horrible writing, think of shibuya incident how that ended, it didn't, we don't see that end, we just have to fill in the pieces and then we're told through dialogue what happened that's bad really bad. It might look pretty, but a shit with glitter on it is still a shit.
The author of this article seems to be confused about pronouns, Imu is a her and if her isn't specified the default is he/him/his not they/them/their and certainly not theirs. This is basic grammar at secondary school level failed.
