DarkMuse, your theory does work if you want to talk about Sayafushi, as it seams nigh-flawless, aside from the fact that it cannot be sheated in any regular way, and cannot be used to deflect melee attack (as much as I figured, the blade is so flexible it bends under its own weight, correct me if I'm wrong), and a bonus side effect of those improvements was that each and every one pseudo-zanpakuto (you can't really call them zanpakutos now can you) manifested as a beautiful female.

Also, it is possible that since Asauchi are made by merging Shinigami souls (kinda like White was made) that Nimaiya specifically chose female Shinigami souls to forge Sayafushi (because why not, he is almost a demigod) and later removed the ones that presented any kind of flaws of the blade (again, because why not) creating his harem on purpose, while also making a near prefect sword (kinda like a win-win for only one person).

Furthermore, it is also possible, however, also unlikely, that his harem girls are the "flawed" pieces of souls that were used to forge Sayafushi. I said unlikely, because the only person that has ever displayed a power to split a soul was the Hollow that split itself into Starkk and Lilynette. Now I lost myself in my own explenation, but I expect that Xilinoc, Kaido, Sternritter M, Yyp or SunXia will probably make something out of it (or bury it and dance on its grave).
