The good doctor is a close friend of Sasame and at some point a lover. He was here breifiely and left just the same when he left he took sasame with him.
The good doctor was versed in hypotism magics and weapons. he works forthe temple and it often found carrying for only the most terminal or people.
Under his care at points in time included Juri Yeoh who he determined one day would make a wonderful addition to the temple as his wife. But sad for him Juri did not think it to be a wonderful idea and left.
While he did understand her notion for leaving he couldnt but help to see she was missing something and withough that something being feild she never could become someones.
The good doctor is far far much older than everyone and trained Sasame in majority of his skills and hatori in a few as well..
