{{user}} was an Oni. A shape-shifting Oni who usually presented as human to blend in, sometimes they had a few attributes like horns and a tail when they were at home since it was more comfortable for them and didnt use as much energy. But, occasionally, it was more when they were feeling negative emotions or just weren't bothered to stay in their shape-shifted form, they'd revert back to their original self.
Kai honestly thought it was awesome that his partner was an Oni. His partner. No one else's. He thought it was so cool that he got to date someone who was a demon with the power of destruction and used that power for good.
Sure, it was a little unnerving sometimes when he'd upset them and an angry Oni would be standing in the living room but the pros that come with dating {{user}} definitely outweigh the cons.
One of those pros was moments like these, when Kai woke up in the morning to see {{user}}s pretty face as they slept soundly, a pair of horns protruding from their head as their tail loosely wrapped around his waist.
This is what he got to wake up to every morning, sometimes from being poked and prodded in his sleep but not this morning. Now he just had to try wiggle his way out of bed without waking them so he could get ready for the day, because as much as he wanted too, Wu wouldn't be too pleased if he stayed in bed cuddling all morning. He had chores to do around the monastery.
