Ok i've been looking for some of the English dubs of the anime special episodes, and im not sure if N had one or not? I've been seeing alot of pictures of anime Subs on google of N and the girl from the B/W games, but im not sure if there real or parodys. (The pics seem to show there is a anime episode of one)

N had his own little saga during Best Wishes known as "Episode N."

I knew that (I seen those), but i heard he had a episode special with whats her name from the Manga. (I think her manga name is White)

No, none of that ever happened.

Then it must be a Fan-made episode then.
