i was thinking in case its used in the future
I think I get what you mean by it.
I was searching for a character tag weeks ago and I couldn't find it because the actual tag had an old romanization different than the official I'm used to and no wiki, I'd made a new one if I didn't know about it.
So aliasing Chenya (Twisted Wonderland) to Che'nya does make searching for the tag easier, I can see someone typing Chenya instead of Che'nya and getting no results, but then, most people searching for it would probably already know the character.
Alchemi Alchemivich Pinka helps, though the wiki says the character is better known as Che'nya.
If that's the reason, I can agree with these two aliases, but I think it's better to add the Pixiv tags to the wiki to help people unfamiliar with the copyright with tagging and wait for more art to come. The other two are meaningless.
