The L5R design of Tia/Hina, was something I wanted to play with for this, I had this originally slated for Haunted when I drew it, I think? But I keep moving things around, refitting where things work as I sketch stuff, just to find a place for things.
The wings and antlers were sketched swiftly when I originally did this, but on looking back I decided it'd be an interesting take on things to keep them that way and roll a more demonic variant of Tia out. They wouldn't be canonically like that for her L5R model, but as a shugenja, there's nothing saying she couldn't magically make herself look that way just to be spooky while she's out somewhere being sneaky-stabby. So... it's just for the look. Not changing her wings and antlers.
