Iris Zero/Headscratchers


 * I know  is Manipulative Bitch, but how the hell did she manage to traumatize people with Irises like "see what's for dinner"? It doesn't seem to be even close to a level of trauma one may get from seeing others' lies or even being able to guess "does this person is suited to be may boyfriend". It's hard to believe that kind of power to be a curse.
 * It's pretty simple - because of her past, and her iris, she got quite good at manipulating others' feelings over time. That means she doesn't need to convince them that using their irises is bad, she has to instead crash their minds to make them avert using it, either consciously or subconsciously. Which is easier than it sounds, considering that they're teenagers.
 * She also doesn't get everyone with the curse, merely that the ongoing Iris hunting is crushing the student body in general. Everyone's afraid they'll be next, and possibly that the curse might be infectious (note how Toru is treated, as if mere proximity can spread his "Zero" status). It's amazing how you can oppress a whole group by making an example of just a few prominent members. And if it was an Iris power (as most would immediately assume), then by the logic of Irises, it must be something that requires looking at someone, perhaps even meeting their gaze. So nobody wants to look at anyone else (how do you know the other person isn't the hunter? how do you know the victims can't spread it?) and any Irises that are based on reading other people become effectively negated even without the hunter's direct intervention.
 * Did Asahi feel anything concerning what she did to Toru? I'm sorry, but the severe lack of an apology from her just makes their reconciliation confusing to me. Why would, should, or how could he forgive her for ruining his life and how can she have such a severe lack of guilt about it? Their entire relationships as teens makes absolutely no sense to me.
 * Probably the big deciding factor is Sasamori. Toru couldn't really bring himself to say no to her even from the start - being around her lets him forget, if only for a moment, how much he's hated and how hard he had to work to attain a modicum of peace in his life. He can "forgive" Asahi for Sasamori's sake, and pack his resentment away enough even to fool himself and her Iris. And yet they really don't socialize at all unless someone else (usually Sasamori) is present, or else Asahi has a problem she wants Toru to solve. They're not really friends, which Asahi may be hinting at when she brings up all the tensions within the group. And can you imagine Toru actually accepting an apology if she came to him with one? More likely he'd deal with it like he deals with everything else: shut up, pretend it never happened, and walk away. It's the kind of "forgiveness" that comes from a tacit agreement not to talk about a problem anymore, without solving anything.
