Hot take regarding the Mari vs. Kei debacle:
Kei is right 100%.
To start off, does it not seem
surprising to you that sacrificing Kei was Mari's go-to strategy? Yes, there are all sorts of rationalizations for why that decision made sense given the specific situation. But does it not seem
oddly coincidental that the end result of Mari's panicked problem-solving was her using the person she's currently in conflict with as bait?
I don't think she did that to get Kei killed in some revenge plot, no. But it does mean that, when the tactic of distracting Oro with Kei occurred to her, she didn't immediately reject it as unacceptable and kept looking for alternatives, but instead decided that that was
good enough. And one step down that line of thought was a better, and more selfless, alternative: a wholesale lie.
Instead of leading Oro on a wild goose chase after a secret that actually existed, Mari could've instead invented some
complete bullshit and led him in circles while Hazou ran.
- What she was doing in that scene already relied on her ability to lie to Oro's face (regarding the IN), so her choices weren't restricted to secret capabilities we actually did possess.
- It would've placed more risk on her, as Oro might've later learned that the capability was made-up, but:
- If the lie was well-constructed, he wouldn't have figured it out in the moment, meaning that the day would've ended the same way (Hazou escapes, Mari gets Aura'd).
- Unless Mari actually thought that Oro eating Kei was acceptable, any next-day plan would've relied on not letting Oro get his hands on the "secret capability" anyway, so whether or not it was real shouldn't have mattered.
- I'm not saying Mari should've had to sacrifice herself, but if she had a choice between herself and Kei, and chose to sacrifice Kei... Well, I think it's understandable that Kei would dislike that.
Of course, in actuality Mari almost certainly didn't even think that far. But, again: she didn't think that far precisely because risking Kei felt acceptable to her, the way letting Oro take Hazou
wasn't acceptable.
I think Kei's construction of the situation is spot-on and her feelings are fully justified. There's nothing to "fix", because the current state of affairs is
correct.
