Ryouga is Ranma Saotome's eternal rival and a friend to him, the only one he has outright stated to truly consider as such, arguably the tritagonist, and one of the most powerful fighters in the series. Ryouga's most notable characteristic is that, like his parents (and even his entire family), he has no sense of direction whatsoever. He is unable to go the right way, often sticking to the letter of any directions given to him, regardless of whether the path eventually turns. He has an inability to understand even the simplest of directions or draw any legible maps, once running the wrong way at the start of a three-legged race or getting lost in Shampoo's house for hours; looking for the exit. He cannot even follow someone pointing in the correct direction.
