Sometimes I could really use a wiki description for some characters, like there are for most of the Vocaloids, but the wiki pages themselves or the comments aren't really practical.
On the top of my head right now I can only remember Nao, Visbou, Vistake and the other OS-tans, Saber Lily, Pangya characters, Queen's Blade characters. Basically any character that isn't from an easily "reachable" copyright, i.e. non-anime, non-manga, or less known or popular games. If I think you think of others you'd like please ask here.
A short, spoilerless, description of the character, it's personality and it's context in it's copyright and in fandom, if any, would suffice. Something like the Kaito article.
