Bear Doctor Damashigami is a Damashigami.
He wears a bear costume as a disguise, with a doctor uniform. His true form is a skeleton wearing hood.
When Rinne caught a cold from Rokumon, Sabato sent him with a nurse assistant to poison him, to make him live in Kyoukai and work as a Damashigami. They appear in Rinne’s room in the abandoned club building, claiming they came on behalf of his family to treat Rinne, but their motifs are discovered when the poison bottle is noticed and Tsubasa unzips him, and Rinne vanquishes them both.
