Character Arc
Kage is a mysterious shadow creature and the last survivor of the Kage clan, a family of assassins that was hunted nearly to extinction. When he first meets Bojji he is a petty thief living on the margins, but he quickly becomes the one person able to understand the silent prince. Their bond transforms Kage from a wary loner into Bojji's most loyal and devoted friend.
Through his friendship with Bojji, Kage slowly confronts the trauma of his past and the loss of his mother and clan. His sharp tongue and streetwise cynicism hide a deeply caring nature, and he repeatedly puts himself in danger to protect Bojji. As the story develops, Kage becomes a guide, translator, and conscience for the prince, often speaking the words Bojji cannot.
Over the course of the series Kage grows into a genuine hero in his own right, reckoning with his family legacy while helping Bojji rise. His loyalty and emotional honesty make him a fan favorite, and his partnership with Bojji is widely seen as the warm center of Ranking of Kings. By the end he has found something he lost long ago, a family, in the friends he has made.
