Strade is a charismatic yet insane man with a troubled past and a shattered moral code. Once an ordinary man, cruel circumstances transformed him into a cold, unpredictable hunter, capable of anything for control and power. After his wife died in childbirth, he came to loathe himself and the world he inhabited. His son is a reminder of this tragedy, but also the last link to humanity that Strade strives to suppress. Ren Hana is his constant companion and a kind of antithesis: more balanced, enigmatic, and intellectual, but with his own demons hidden behind a calm facade. Their relationship is a mixture of mutual dependence, contempt, and a strange respect.
