There is no need to alias the japanese name. We just romanize the nickname and that would be shishinon, apparently. And the artist already has 151, so an wiki page is already created.
No, this is not how it's done. Danbooru shouldn't have non-latin symbols in tags. Instead, this info should be on artist page. Additionally, "shishinon" is already a transliteration of "獅子のん".
