Minoo Shidara

Minoo comes from Shikoku and has an accent. She can control a special kind of yokai caled Ogedou, which are Yokai imprisoned inside ornamental cubes (hers similar in appearance to hellhounds), she uses spell-songs to seal yokai, and she can sense Youki (Demonic energy), which led to her sensing Tora's energy around Ushio.

She came to Ushio's school seeking a lost Ogedou of her village from 50 years ago. At first she thought the lost Ogedou was Tora but found out it was possessing the school nurse and wished to possess Ushio so it could wield the Beast Spear through him. Minoo risked her life to prevent that, and even became friends with Ushio.
