Tomohane, the youngest and weakest member of Kaoru Kawahira's inukami pack, stands 144 cm tall at age 11. Her specialized ability to track otherworldly entities first surfaced when she located a mujina hiding in Keita Kawahira's house; after capture, the mujina became her friend and pet. She displays strong admiration for Yoko, visibly excited upon asking if Yoko remembered her, though Yoko's teasing denial briefly upset her. Her chemistry and cooking skills emerged when she baked chocolate cupcakes for Yoko as revenge for Yoko defeating her pack in battle. Unbeknownst to others, she laced the cupcakes with laxatives, causing digestive issues for Keita after he consumed one during Yoko's absence.
