"Sorry for troubling the other groups"
The "other groups" were garbage, the heck you apologizing for?
Anyway,
I can't say I understand why the author thought an actual burden of a character would be fun to read about? There's a reason VIP-missions in games are usually hated. Unless the stage is set up for her to overcome her trauma, then she's just there to be a cool trophy for the MC to powerup for, which is god awful.
