There is nothing in the page of Extra Final Forms that states they are aways outside of series. Also, Sin Specter is analogous to Ghost's final form, Mugen Damashii. The thing is, these classifications are unofficial and made by viewers, and there hasn't been some sort of decison or official definition or guideline. The forms pages had been locked ever since I joined this wiki up until very recently and no one even knows how these things are determined anymore.
