A well known retired onmitsu and the lone grandfather of Jirou Azuma. Toshimasa Azuma even with his old age is still a very formidable onmitsu. Among the onmitsu that are a part of the Bureau Toshimasa may be the strongest of them all. After his grandson Jirou was growing up Toshimasa decided to retire and purely raise his grandson. He chose to do so as Jirou didnt have anyone else to take care of him. Toshimasa is rough on Jirou quite often but he cares deeply for his grandson. The last thing he wants is Jirou dying before he does so he can be overprotective if not a bit violent. Besides that Toshimasa is kind and somewhat young at heart.
