Shirogane

白銀

He appears to be 25 years old. His birthdate and blood type are unknown. He stands 181 cm tall (approx. 5'9") and weighs 59 kg (approx. 130 lbs).
Dressed in his signature black coat and top hat, with long, silvery hair, Shirogane is a mysterious figure who appears before Akira and draws him into the conflict between the shadow world and the human world. He carries a cane that, apparently, can be charged with spiritual energy to repel Kokuchi.
Shirogane conceals his true personality. His manner of speaking shifts to one that is sharply tongueed. His typically calm, smiling demeanor turns colder and more aggressive. This alter ego is shown in the anime during a rooftop conversation with Kou. In the manga, after switching personalities, his cane transforms into a katana, allowing him to slice off Nanaya's arm. In the anime, Shirogane seems to harbor a romantic interest in Akira, though this is not evident (and possibly non-existent) in the manga.
