While Kiba hasen't shown any interest in Tsubaki - beyond that of a comrade - I wouldn't say that the chance for the two of them becoming a couple is impossible. After all, Kiba has started to open up more to people and be less of an enigma laced with girl nip. That, and Rias has mentioned that she wants all of her servents to experience their own happiness in Volumes 5 & 6 of the Light Novels. Perhaps Kiba will take a note from Issei's personality and be more honest with his feelings to those around him. If he does, I can see Tsubaki and himself becoming an item, eventually. However, the subject is still up for debate. That being said, if you have an opinion to my own, I am listening.
