Aliasing riasusikikawaii → riasushikikawaii
Reason: http://d.hatena.ne.jp/riasusikikawaii/ lists リアス式かわいい as the name, which is properly romanised as riasushikikawaii. Or we could go a step further and spell it rias-shiki_kawaii, to ease reading. Btw, JP Wikipedia says リアス式 is http://en.wikipedia.org/wiki/Ria, but I don't think that helps us any further in naming the artist.
