Normally, even in those cases, some focus is put on the MC to make it feel more interesting. Making the MC completely uninteresting and dull is just bad writing. Which is what I meant when I said that even harem anime protagonists feel more interesting.

Even The Hobbit, which is the most recent example I can think of of what you're trying to say, put some focus on the MC at times. Of course, the books were still of much lesser quality than TLotR books and he still felt not very protagony as much as a secondary compared to everyone else, which is bad considering he's still technically the MC, but at least they tried.

With Ruby however, it's like they haven't. Like, she's only there for the same reason as the Grimm: to fill space.
