- It is through Dr. Akai's monologue at the beginning of the series that the world of Maburaho is explained. The resident doctor of Aoi Academy, Dr. Akai is a formidable wizard with great powers of his own. Despite his laid-back appearance, he has Kazuki's best interests at heart. Throughout the series Dr. Akai uses a variety of eye lenses that he carries around and through which he uses his magic. Dr. Akai is quite smitten with Kaori Iba, and sometimes comments to her that he has a "special bed" in the nurse's office just for her.
- Dr. Akai's main interest in Kazuki is that of a research subject, especially after Kazuki becomes a ghost. During the recap of events in episode 20, he reveals that this is the second time he has seen someone's body being restored after their ashes had been scattered. But while he knows how to restore Kazuki's body, he does not reveal the information to Yuna, Kuriko, or Rin.
