I can see why you'd assume. Sadly, I've got to fit this one around canon. I'm trying to write something where canonical events happen but have a completely different meaning because there are more layers. Keeping Ouka alive is the only deviation from canon that will be difficult because things happen after she dies-- because she dies-- that I need to keep the same.

In canon, her death is useful to the villains. In this version, however, actually killing her would wreck the lead villain's long term plans. But, if people generally know she's alive, I have to make fairly major changes to canon and have to write those changes so that readers know what's going on.
