Aliasing hyakka-ryoran -> hyakka_ryouran_samurai_girls.
Reason: The full name is better than a short one, plus "Ryouran" is better romanization than "Ryoran". I also don't see the need for a dash instead of the usual underscore.
For that matter, it may be best to alias hyakka_ryouran to the full name, too. (It has one post thus far, and there are bound to be people who'll try to use it.)
