She started to look the other way bcs of Michiru, she's feeling guilty for the people she killed since they're not all that bad. After she discovered that the government lied to her abt her parents death (which was her resolve to kill the talented) she's doing her best to atone her sins tho she knows that it's not something that can be atone so easily. In short, she doesn't have any reason to murder her classmates
because all she's done for a while is make surprise pikachu faces at everything, whereas before she was a lot more intimidating? calculating, nonchalant and even seemed less naive too.. being able to predict how her opponents will move next and show off her skill set (which is what I'm talking about) its a stark contrast to how she is now where there is very little opportunity to do that..
we dont really get to see her strengths anymore now thats shes quote on quote GOOD GUY. thats means... no evil smug smirking, no ruthlessness, no cold condescending appraisal of others, looking worried and unprepared 24/7, always being somehow caught off guard by the antagonist henchmen plans.
I feel like kyoya's already currently covering the role of good guy/detective, so where does she fit in now? it would be boring if she just became another detective, it wouldn't really make her stand out apart from him in a way she did before.
I'm sorry if I'm not explaining it very clearly, but it was something I was worried about very early on during the first hints of her redemption.. how she would be written after her change (I had no issue with her getting one..) that she would lose whatever made her interesting before by becoming more generic. the premise, and the moral ambiguity of the protagonist is what drew to this series in the first place..
I kind of hope she can stay more of an antihero (we dont get to see a lot of female characters like this) while kyoya is the more preachy good guy one but maybe thats just me (づ ̄ ³ ̄)づ
Since nana started as a killer in this series why did she become let's say soft? She should finish what she started or Imma come and finish her #-.-)
