So I just wanted to see if you had any particular ideas/pairing for Ariel?
well he is a young master of his families main house, so I guess he could be a slave or his secret lover that no body knows about, and the other can be a human or a Celestial beast like Ariel. You can either make your character have the opposite personality from Ariel's. the partner could be like a young master that is a Yakuza outcast. You will have to choose what your character is going to be like since he will be a seme not a uke.
