This series is great but I keep thinking, what was the chance for Seiran to survive if she just told Mimi to heal her...
Yes, probably. At the same time, I feel it's perfectly in character and makes sense that she wouldn't. It feels, for lack of a better term, perfectly appropriate, that it was exactly like her to act as she did. The whole way in which the story unfolded feels very fitting and right, for lack of better terms. Besides, I feel that nothing else would've had the same impact.
In any case, this series hits in a manner very few, if any, ever have. It's so hard to read at times, but I can never resist reading it, I constantly find myself drawn to it, it's just so good. I agree with the fellow above, this is going to kill me at some point.
