So not even remotely true. Kais scenes were picked by Akira, this has been common knowledge since day one. The only reason it hasn't been usable on here is due to some fighting about it. Super anime is 100% canon whether you like it or not, and it makes enough references to Kai that it too is canon. The movies were retconned out of existence thanks to it. The manga is a side project that neither Akira, nor Toei have anything to do with, while Akira works closely alongside the anime script(http://www.techtimes.com/articles/12...cript-make.htm), while he has nothing to do with the manga whatsoever, making it 100% non-canon.
