Honestly, I don't really like Nana. Usually I like characters like this, but she kind of gets on my nerves. Sometimes she is like - oh no I'm so sad I killed him, but then she's the complete opposite - I'd be happy to kill you. Also she's portrayed to be this grand genius that can even pretend to mind read, but then she forgets to clean up evidence? Tbh I should probably just lower my standards, this is a pretty good manga.
