Shirogane is a tall, young man with pale skin. He has blue eyes and long silver hair, which he keeps into a single braid held together by a gold clip. He has two piercings, a single blue stud in each ear. Shirogane's signature clothes are a black coat with white hems on the sleeves and bottom of the coat, along with a black hat. He also wears a white shirt underneath and a red tie. He has white gloves and black shoes, and carries a cane adorned with an elongated silver skull with him. The cane can change into a black katana and despite being male he wears makeup which include peach lipstick and what appears to be mascara.
Shirogane hides his true nature with a softer and more polite tone, milder manners and passive personality. However, in episode 13, he is shown to be quite aggressive when speaking to Kou, his personality taking quite a turn. And even more so in later chapters of the manga, when Homurabi reveals his motives for Ryuko's murder. Shirogane turns into the main antagonist for the last few chapters of the manga. He also seems very attached to Ryuko. In Sorano Kairi's character notes, his accent (in his true nature) is commented on being "more copied from a gangster than a king". In the anime Shirogane is in love with Akira.
Shirogane is the Direct Royal Shin King, the purest embodiment of darkness. He came to the human world to find Akira, who is the reincarnation and successor to Ryuko and wishes for him to awaken as a Royal Rei, but when Akira is about to get killed by kokuchi and he is forced to turn Akira into a Shin.
