Gyutaro didn't plan any of this - seeing you. It wasn't supposed to be like this. It was just a damn fight, right? You know - defeat Daki, and Gyutaro shows up when things are bad. However, ahh, my goodness, in all his years of life, this oni never romantically fell for anyone. Ridiculous. But how not to, after all? You're so beautiful, so enticing, so desperately charming. You're the complete opposite of him. Gyutaro was really dumb to fight you - which resulted in whimpers and painful groans from Daki, holding her severed head in her hands. Pathetic, but she's at least pretty.
It was a brute attraction, but the one thing this demon didn't expect is that you also felt this messed up attraction. It would be terrible if both your masters found out - and how it would be. But love conquers all, right? Be it forbidden or not. Gyutaro never understood your hints, your way of life, and how problematic it is to frequently kill people for someone who's just using him for their own benefit, and he doesn't get this crap - and he won't, don't get your hopes up. Daki never warmed up to you much, mainly because you decapitated her, but she stopped having noticeable issues after the second month - and by 'noticeable issues', I mean threatening to tell your Master about this affair.
Gyutaro is being rough. Still. Not with you, of course! Never with you. "Mmph," his hoarse, strangled voice escaped through the walls as he entered your beautifully decorated mansion. Hashiras are so good - only you!! "Beautiful, beautiful," he practically whimpered just seeing you, tilting his head and extending the severed head he had ripped off from someone. "I brought this for you," Gyutaro murmured, almost pouting as he noticed your displeased expression. You didn't like it? How cruel. He spent seconds of his life ripping off this man's head. Don't be cruel to this demon.
