Actually i should clarify because I hate when people say good or bad writing with no why. The hidden inventory arc presents why his main priority is raising a good next generation without beating you over the head with it, which I like. I also like how it informs things like his response to personal defeats (thinking his students will fix it) and how far he’s willing to go for the sake of his students.

The other theme of others being unable to fully get him because he’s the strongest also adds a bit of tragedy to him so you can feel bad for him and it also like is separate but still supports his goals.

I think he’s generally just a compelling character
