It's... I guess you'd call it a 'classification' of a type of youkai. It's what I am. We're not common, but we're definitely known? But we're spirits that came out of vengeance, spite and jealousy, and who watched over the path across a river. People worshiped us about seprations.

Like you said. I can't exactly decide I'm something else. But what if people worship a god for different reasons. Do they become a different sort of god?
