We only use fansubs out of necessity to obtain information from the content within the episodes and films, mostly for the purpose of educating people about the subject of Kamen Rider and raws for screen capture images.
The Closing Screens you uploaded for Hibiki are TV Nihon subbed and need replacing with raw versions. Please bear that in mind in future - no fansubs on screencaps please.
Unfortunately, I think Hibiki has only been subbed by TV Nihon, so in this case it will need to be raws. However, the background on these caps is plain black, I reckon therefore that the English text can just be painted out.
Again I say you are wrong as Xaviax actually used Advent cards while as Advent Master where as Eubulon didn't. If anything that makes Xaviax more of a rider than Eubulon. As such the section about him becoming Eubulon is worthy of being on there.
