I'm not looking for spoilers about this; the comment section groaning just made me think about the theories some more.
Folks are now claiming that the reason the manga seems to be supporting a theory as it unfolds is that they read the raws. I'm hoping that's not true; I'd prefer to believe the best of those people. The thought that got me started thinking was "Which theory is it?"
To my count, there are four theories that have been suggested:
- Everything was as it seems and she really does accurately read minds
- She gains impressions of some kind but interprets them according to her own thoughts
- She doesn't have telepathy and is actually just really good at reading people
- Everything is her own delusion and not necessarily connected to reality or people's thoughts
It seems like these theories run a full spectrum between delusions and her being able to understand people extremely well, so, barring something completely out of left field, the truth has to be within this space.
The first theory has some issues, but it's what most people probably believed until relatively recently. The problems are mostly in the form of her mental picture not lining up with reality (Akira's girlfriend, Toda crying, the chocolate sandwich, et cetera). But she's able to converse extremely well with Mana when Mana is just thinking, so that's a strong point in favor.
The second theory seems to be going strong. The opportunity to challenge it hasn't really come up, I think. I'd welcome some criticism of this theory. Maybe the language matches too exactly with what she interprets people to be thinking? Maybe she just doesn't correctly see images but their word thoughts are clear?
The principal problem with the third theory is the time where Akira thought that Mana's curls look like croissants. I can't imagine how you would read that from body language. And how was she so good at this from an early age?
The last theory seems the least unlikely. Everything would have to be extremely coincidental for it to work.
And who knows, maybe her powers are in flux or something and all of this is moot. Maybe NOBEL wasn't initially as concerned with her telepathy and it's only been more recently that they decided to take it in this direction.
