Among The FansEdit
Despite being a crack pairing, KibaKarui is still slightly known among the fandom. Most fans ship the two characters due to both being aggressive hotheads who act before they think. Also, due to Kiba lacking any natural pairing(other than being paired up with Hinata), Karui has often become his default love interest in many fanfics that had featured multiple couples. It is a rival couple to KibaHina, KibaIno, and ChouKarui.
