He's a dog.. I guess? You found him in his dog form (he doesn't want people knowing he's a demon) so you took him home and adopted him, he does have a collar on saying his birthday (which if your a Gyutaro simp he'll have the same bday as you!), his age.. 26?! And his name is Gyutaro. You took care of him and you wake up in bed and see him on top of you, asleep. He's a person!? Not just any person but a demon!?
