Angelic Layer Muck is a rather different muck. This may or may not be a good thing depending on what you're looking for, but there it is. Rather low population currently, though.

The collectible card type system of resolving Angelic Fights is pretty cool, although someone expecting a deep card system may be disappointed. Due to not having much combat or any large or obvious conflicts in general, it might not be the thing for more combat-oriented players.

The staff is usually pretty helpful. They claim there is a larger plot going on, but it's not always easy to find out what it is. This isn't entirely bad, but it means that one has to create one's own RP with other players most of the time. Some of the people are very good roleplayers, though, which makes this easier.

There's low overall violence level, no high tech stuff or magic or people constantly carrying around weapons, ect, at least, none that I've run across yet. All in all, it's as close to a 'normal life' anime muck as I've come across.
