I'll kind of torn. I like this but nothing we've seen really shows their inner maturity.
I'm not talking about their reactions to getting abused. Anyone at any age wouldn't react well to that.
I'm talking about their learning. I would fail the balance book test/graceful walking since I'm a major klutz but learning in general shouldn't be too difficult, right? Like probably not genius level good but I would think they wouldn't lag behind that much.
Hmm. Maybe it's all those isekais that paint everyone as geniuses that's skewing my perspective but I would think since they had some learning in their previous life, they would be able to do fine.
Note: Just to make things clear I'm not talking about Ishina's evaluation of them. I'm basing this on what they themselves have said about lessons being hard.
