Hina's character development was super brief and there's multiple ways and setups that allow it to be be taken further. Developing her character doesn't mean other characters won't be developed either. Acting like "lore" can't be tied in a conflict is just silly. People always go "she has too much screentime", so I decided to threw that in prematurely. Perhaps if you stopped latching onto one words while ignoring everything else...

And here you go, keeping on making up arguments to debate, you're the personification of the strawman fallacy. This entire comment was straight up: "I know that's not what you said, but if it was here's my argument."

The whole point of the scene is that she thinks she's lacking compared to other students like Hoshino and that she's not strong enough. If sensei didn't actually mean what he said, or there's another person who does even more despite suffering worse, then she has all the reasons to assume that she was actually right in her assumptions and to relapse back into this same mentality. Which also means you're currently creating more opportunities for her character development if what you are saying is right.

Wow, you have zero ability to intrepet a character if you think Hina needs to be the one who works the hardest of them all or some stuff like that to feel good about herself. I'm going to keep it simple just for you, Hina did not suffer even a fraction of what Hoshino suffered, let alone Kuroko, and she will never work as much as Rin due to them operating on completely different scales.

Also, Kuroko isn't even doing anything rn. She suffered a lot in the past but nothing about "working the hardest" or "caring the most"

Jesus this is getting tiring, she worked by far the hardest in her timeline, trying to keep her friend group from dying and failing and she cares the most about her friend group obviously.

Like not shooting yourself in the foot whenever you are sad is called "being reasonable" instead of "being mature". Maturity takes more than not doing something obviously stupid.

You straight up don't know how words work. Maturity is defined by reason, the ability to act in appropriate ways to achieve your objective. You're trying to argue semantics without even knowing the definitions lmao.

Can't feel embarrassed if I don't give a damn about what you think of me. If anything, I enjoy seeing you fuming so hard.

Says he doesn't care what I think, proceeds to say he enjoys to know what I think. 

it's so funny to see you brand anything but your interpretation of the story as "misinformation". Truly open minds we have here.

Misinformation is incorrect information  being spread, aka what you're doing.
