Absolutely, she is a great character writing wise, but I definitely wouldn't want anything to do with her until she gets help.I do not like Noriko. Gives me a bad vibe. Which to me, means the character has been well written. I like that I don't like her.
This game occupies way too much of my brain's idle processing, I love it.
That's the thing with crazy, you never know who all the crazy ones are. As for self harm, the biggest risk is actually Rin, Noriko is way too open with her apprehension toward sharing emotionally, but Rin has depression AND a history of self harm already. Ami would definitely go ballistic, possibly in a literal sense, and I feel Noriko would as well, igniting a love war between them. I could also see Noriko targeting player Sensei for social fuckery and/or elimination yandere style. He would more than likely blow up at her for fucking up his life and she would feel betrayed beyond any reconciliation and, if she really turns out to fit the yandere archetype, she'll eliminate him in a fit of 'if I can't have him, no one can.'Yea those are valid points i just tend prefer my crazy out where i can see it. With Noriko, the MC knows she is crazy and can at least try to avoid the crazy situations. But like you said when it comes to Ami, he is clueless and i dont think would see it coming. Also i feel Noriko would be a bigger risk of self harm instead of harming others, whereas Ami i think would go ballistic and certainly harm. Not saying it's impossible that Noriko would do something like that as well, just that i find it more likely with Ami. I do agree that Noriko would be more likely to fuck up MC life in other way, such as socially by telling people about the relationships as well though to try and force him out of those relationships
And with the Harem thing, If we are talking in game then yea i am cool with a Harem. When i say i would not want a harem i mean in real life. Games are an escape and chance to do these things without the real complications of them for. Same reason that i creampie and knock every single girl when possible in these games even though in real life i am not too fond of kids.
I'm not sure on a real life harem, it would be nice once out of the whole issue with favoritism, but it's kind of a social no no in certain areas. Not necessarily illegal, but socially unwelcome.
