Well, the secret is out, I guess. I've been writing different versions of this story under different pen names. I didn't want to tell anyone because I don't need a bunch of people telling me the new version is much worse - I've gotten that reaction before to story rewrites.
But the other two versions of this story, also written by me, are:
The Kunoichi Three by Grimrose Eilwynn
The Kunoichi Diaries by MistressPsyckoBookwormFreak
The Kunoichi Diaries is my latest rewrite. If you like it less, don't bother telling me - I've sort of been expecting that reaction.
