Recently I decided to go with changing my name to past clans I was in. The most recent being Ryuuko Meshikakae.
Ryuuko for this clan stood for the Dragon & Tiger
Meshikakae stands for a group that's for hire.
It was a Ninja clan based on the culture of ninjas, naturally Naruto at the time had heavy influence on the clan. It was a RP clan so we did quite a bit of roleplaying.
It's a fairly old one though.
If you have questions about it feel free to ask, I'll be choosing to change my name to another old clan I was in soon enough. I plan on going through several old clan names and go into a little bit about them, of course too. Some of them of course I was only a member of while others I was a clan leader. I happened to be one of the clan leaders of this one, but I didn't start it.
