Aoi has a telekinetic ability, which allows him to manipulate the speed of objects around him. While it proves to be useful for situations such as dodging bullets, it appears to have a time limit on the duration of use. To hide his identity as a spy, Aoi runs a photo studio together with Kazura. He has a lively, positive spirit, and a great sense of justice, but tends to act rashly in certain situations. He is proficient in Chinese, Russian, German and English and used to live in Europe for quite some time.
