Back to an info dump while the investigation takes FOREVER (spoilers if you're not caught up)
Lowkey love how Kazue's just repressing her negative thoughts/feelings, and how her breaking point was her hiding her rule so she'd die- bc lowkey she genuinely thought it'd be better that way.
Ironically enough, Tsuneo wouldn't have killed anyone even if she did tell him about her rule- don't get me wrong he'd absolutely offer and think about doing it constantly, but he wouldn't have gone through with any of it because he's already terrified she hates him for being Genocide Doll, the last thing he needs is another reason for her to dislike/fear him. If he and Jun knew, they'd just grow even more determined to find the Mastermind and have a whole side plot about that
Of course Kazue had no reason to think any of that would've happened, I mean she literally found out her best friend was a SERIAL KILLER just days/weeks after her half-brother was murdered, not to mention she's still under the impression that her family, friends, and fans outside the hotel are dead, but I mean
Doesn't change the fact that what she did was basically a suicide attempt (which would've succeeded had Koharu and Hitomi died just a ffeeww seconds later than their current Time of Deaths)
