If I am playing a CYOA and the choice comes down to "Kill the girl and live" or "Let the protagonist die" then obviously she dies. You don't play a CYOA to kill off your protagonist. You take the hard rolls as they come.
I would like to point out that there might be exceptions (We're in the Nasuverse, there are exceptions to every rule).
However, as much as it pains me to say this, I would have to say agree. However, we will not have protags/protag candidates going out like punks. There will be last stands, tearful goodbyes, sheer epicness. At least, as much as can be had without breaking that ever-important Suspension of Disbelief.
By the way, this is my opinion regarding the death of any of these three, or any other major charaters, within this CYOA. If this was my general policy, there would be no way for me to enjoy Attack on Titan.
Lol, whiteknighting even Not!Sakura.
*Sarcasm mode* Bro, I have no clue what you're talking about. Just because we lack worms doesn't mean we can't have shrinking violet Sakura...
Seriously, though, there is more to her than the worm-rape. Enough for white-knighting? Debatable, but she has appeal all on her own. Don't make me give my take on the exact appeal. I don't want to risk starting a flame war before I've even hit 10 posts here.
To quote another member of the board, I don't want no trabble.
