Kyoku,from my old,but yet current manga +Tha darknes of my heart+ though,the title will chnage due to different arcs. She's a pure blooded dog-demon,she's not a cat,because in the filler eps with the cars,sesshomaru did not save them on his own accord,it was Tenseiga telling him too,so he does'nt like cats,she's not a wolf,because wolves killed Rin,duh,why would he love a wolf after they killed Rin,and hse's not a fox,because,a fox seems like a weird pair for him,sh'e s dog-demon,yet,she never transforms in the story,because she's to ill to.
