This one still have too much characteristics.
I suppose thats true for most yukkuri, but as not everyone is familiar with Kingdom Hearts and Riku's history, I wanted to give some of that and describe the major traits of the Riku Yukkuri. Trust me when I say I had way more I thought about adding. I'm one of those types who's big on describing things. Been thinking about writing my own stories soon too.

Really only the fallen should be worrisome. And while they might be able to draw some blood they're brighter than the average yukkuri in that they instinctively are cautious of humans and wouldn't attack them unless provoked.
