My attempt at a Lora for Riju.
I think this one is pretty good, I haven't added anything for alternate outfits but feel free to give it a go.
Adding gerudo might help out sometimes with keeping the generation in character - but it seems to work without this tag as well.
If you're going for Riju exactly as she is from the games, just add something like cute or young and then BE SENSIBLE! That will put her much closer to her younger appearance like she is in the games.
