World building or character development?

Dude, I get it. You're a OP fan, it's impossible for it to have problems. It's the best selling manga. Money = Quality

But not talking about personality change here. More like maturing and acting like an adult, gaining some human sense.

Not crying waterfalls and snotting up the place about shit when you're like 18-19 yrs old. But then again, OP has tons of adult characters crying like children. But it's all preference at the end of the day.

For reference - Let me make a comparison to your favourite character Naruto. That dude last cried on the 1st day he became 17, and hasn't even teared up since. Even when he was really sad, because unlike some characters, he wasn't a 13 year old boy anymore, and couldn't act like a idiot.

P.S. Most of Naruto's core personality didn't change either, but he did gain perspective on people and situations and his views matured is all.
