A very well-written, rather epic story, and Krista really "gets" what makes Akane tick. If you took away the rage disorder the original was easily one of the most genuinely compassionate, idealistic, brave, helpful, and heroic characters in the series, so I think this story
summarised it pretty well.
Here the flip personality of a violent paranoic is toned down, but Akane usually managed to keep it under control when people relied on her, and has to given the serious situation. She also greatly patterns herself after Kasumi, so I thought the development made sense, and personally I much prefer reading about genuinely sympathetic characters.
Regarding her skill, she was stated outright as having more potential than Ranma, has now been given several extra years of training, and I don't remember her being a bully
about it, so it's mostly okay.
Possibly not enough humour thrown in for a Ranma story, but there were a few more serious manga arcs, and it doesn't enter Cerebus Syndrome
territory. It may not be an actual masterpiece, but still very good, and going by what I've seen over the years, most writers seem to enjoy it.
