Can one ten yen coin change the course of events in the Ranma universe? You betcha!
Ranma has something Nabiki wants. 10 yen to be precise. But not just any old ten yen, a special one. How is it special? Well, Nabiki doesn't know but she's crazy to find out! How far will she go to find out, and how far will Ranma go in this game?
Ranma plays a joke/mind game on Nabiki, but the consequences reach further than he first imagined.
