Ranma leaves Nerima and joins a special police force. Special in that it's made up of psychos, fools, and nymphomaniacs all charged with protecting Tokyo from the supernatural and terrorist forces that plague its streets.

Ranma accidentally gets summoned to another dimension. His presence is quickly taken advantage of by certain entities. And there we have the beginning of a very long Journey. Arc 3, Chapter 12 and 13 up.
